1 Introduction
The HP StorageWorks virtual library system (VLS) family consists of RAID disk-based SAN backup
devices that emulate physical tape libraries, allowing you to perform disk-to-virtual tape (disk-to-disk)
backups using your existing backup applications. The VLS family includes different series of models
that vary in storage capacity and performance.
The VLS emulates a variety of physical tape libraries, including the tape drives and cartridges inside
the libraries. You determine the number and types of tape libraries a VLS emulates, and the number
and types of tape drives and cartridges included in each tape library to meet the needs of your
environment. You configure the size of the virtual cartridges in your VLS, which provides even more
flexibility.
The VLS automigration features allow you to establish data pools to create and manage mirror (echo
copy) or snapshot (smart copy) replication of data for additional protection against data loss.
Deduplication provides the functionality in which only a single copy of a data block is stored on a
device. Duplicate information is removed, thereby reducing the amount of storage used by a given
data block.
The VLS accommodates mixed IT platform and backup application environments, allowing all your
servers and backup applications to access the virtual media simultaneously. You can specify which
servers are allowed to access each virtual library and tape drive you configure. You can change the
default LUNs assigned to the virtual library and tape drives for each host as needed to accommodate
different operating system requirements and restrictions.
Data stored on a VLS is easily cloned to physical tape for off-site disaster protection or long-term
archival using a backup application.
This section describes the HP StorageWorks 300 and 12000 Gateway virtual library system models.
VLS12000 Gateway Components
A VLS12000 Gateway consists of at least two nodes (one primary node and between one and seven
secondary nodes) and dual LAN switches for internal inter-node connections. See the drawing of
racked nodes below. In addition, each VLS12000 gateway node contains hardware data compression,
dual processors, one 4 Gb quad port Fibre Channel HBAs, two 2048 MB memory modules, and two
60 GB SATA hard drives.
NOTE:
A VLS12000 node can be used as a secondary node (an upgrade) on a VLS300 system. In order to
do so, the VLS12000 node is set to compatibility mode (to disable hardware compression) when your
service representative installs the node.
No external storage is included with the VLS12000; instead, the gateway uses external storage in
existing arrays.

Ethernet Switch 2810–24G (1 Gb)1
Ethernet Switch 2510–24 (100 Mb)2
Node 0, primary node3
Node 1, secondary node4
The two nodes include a base license to configure up to 25 LUNs, ten LUNs per gateway node plus
five 2 TB upgrade licenses, which gives the gateway up to 50 TB capacity.
Up to six nodes can be added to a gateway for a total of eight nodes in a single gateway. Each
additional node adds licenses for up to ten more LUNs and increases maximum external capacity by
up to 20 TB. Capacity can also be increased by purchasing capacity expansion licenses, each of
which adds licensing for one additional external array LUN and increases maximum external capacity
by up to 2 TB.
Adding nodes and licenses increases the gateway storage capacity as shown in Table 1. Adding
nodes also increases the performance. See the HP StorageWorks VLS12000 Virtual Library System
Quickspec on the HP web site (http://h18006.www1.hp.com/storage/disk_storage/disk_to_disk/
vls/vls_gateway/index.html) for performance data.

2 Hardware Installation
This section details the steps to install the VLS hardware from installation preparation to final cabling.
Preparing for the Installation
Prepare the EVA for the VLS12000 Gateway
Arrays that will be connected to the VLS Gateway must already be setup with the appropriate
configuration as described in the solutions guide, including:
• Command View EVA is installed, at firmware revision 5100 or later, and functioning properly.
• There are either two external Fibre Channel switches/fabrics or two zones on an external Fibre
Channel switch/fabric so that there are two (high availability) data pathways from the VLS Gateway
to the EVA.
• All of the VRaid LUNs required for the VLS have been created on the EVA according to the design
guidelines (for example, each LUN is roughly the same size—2 TB is preferred. The LUNs can not
be read-only. RAID 5 is recommended. Path failover is balanced across both EVA controllers).
NOTE:
Minimum capacity for EVA LUNs is 100 GB. Ensure all EVA LUNs attached to the Gateway meet
this requirement.
If this has not been done, refer to the solutions guide for instructions.
Tools for Installation
• Two people
• #1 and #2 Phillips screwdriver
• Box cutting knife
CAUTION:
Do not use any power tools. They could strip or damage connections.
Taking ESD Precautions
To prevent damaging the system, be aware of the precautions you need to follow when setting up
the system or handling parts. A discharge of static electricity from a finger or other conductor may
damage system boards or other static-sensitive devices. This type of damage may reduce the life
expectancy of the device.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 17
Page 18
To prevent electrostatic damage:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or assembly.
Grounding Methods to Prevent Electrostatic Discharge
Several methods are used for grounding. Use one or more of the following methods when handling
or installing electrostatic-sensitive parts:
• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis.
Wrist straps are flexible straps with a minimum of 1 megaohm ±10 percent resistance in the
ground cords. To provide proper ground, wear the strap snug against the skin.
• Use heel straps, toe straps, or boot straps at standing workstations.
Wear the straps on both feet when standing on conductive floors or dissipating floor mats.
• Use conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized reseller
install the part.
For more information on static electricity or assistance with product installation, contact your authorized
reseller.
Unpacking
Place the shipping carton as close to the installation site as possible. Before unpacking the VLS, inspect
the shipping carton for damage that may have occurred during shipment. If you detect any damage,
notify the carrier and HP before unpacking the unit.
Removing the Packing Materials
To unpack the VLS:
1. Open the top of the shipping cartons.
2. Carefully lift the units out of the boxes and remove the packing materials.
3. Place the units on a stable work surface.
NOTE:
Inspect the units for any damage that may have occurred during shipment. If damage is
detected, contact your authorized service representative.
4. Remove the accessory kits and documentation from the shipping cartons. Set them aside for later
use.
5. Place shipping materials back into the shipping cartons.
6. Set the shipping cartons aside for later use.

The rack resource kit ships with all HP or Compaq branded 9000, 10000, and H9 series racks. A
summary of the content of each resource follows:
• Custom Builder is a web-based service for configuring one or many racks. Rack configurations
can be created using:
• A simple, guided interface
• Build-it-yourself model
• The Installing Rack Products video provides a visual overview of operations required for configuring
a rack with rack-mountable components. It also provides the following important configuration
steps:
• Planning the site
• Installing rack servers and rack options
• Cabling servers in a rack
• Coupling multiple racks
• The Rack Products Documentation CD enables you to view, search, and print documentation for
HP and Compaq branded racks and rack options. It also helps you set up and optimize a rack in
a manner that best fits your environment.
Rack Requirements
HP supports the HP System E racks and the HP 10000 Series racks for use with VLS systems. Other
racks might also be suitable, but have not been tested with the VLS.

Hardware Installation32
Page 33
3 Multi-node Setup
This section explains how to configure the identities of each node after the VLS12000 Gateway is
physically installed.
Configuring Primary Node 0
To configure the primary node:
1. On the primary node, connect to the serial port or use the keyboard and mouse ports to connect
to a console.
2. Power on the primary node.
After several minutes, a menu will appear on your monitor asking whether the node is a primary
(master, m) or secondary (slave, s) node.
3. Enter m. The node will then run cable checks and configuration checks.
4. After the checks are complete the node will reboot automatically. Wait for the primary node to
fully boot.
Rebooting is complete when you receive the “Initializing node#” and then “Initializing for node#
completed.” messages in the systems notifications (if you have DHCP enabled) of Command View
VLS or when you see the login prompt on the terminal.
5. Set the IP address and other public network configurations on the VLS. Refer to Setting the Network
Settings for instructions.
Configuring the Secondary Nodes 1 through 7
To configure the secondary nodes (nodes 1 through 7):
1. On the secondary node, connect to the serial port or use the keyboard and mouse ports to connect
to a console.
2. Power on the primary node and all previously installed secondary nodes of the VLS.
3. Power on the secondary node being added to the VLS.
After several minutes, a menu will appear on your monitor asking whether the node is a primary
(master, m) or secondary (slave, s) node.
4. Enter s.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 33
Page 34
5. At the prompt, enter the node number (next sequential node number).
The node will then run cable checks and configuration checks, display the world wide part number
(WWPN), then reboot automatically.
NOTE:
If you are performing a "hot add" of a secondary node, you can present the LUNs at this
time. See “Presenting the LUNs” on page 35.
6. Once the new secondary node has finished rebooting, log on to Command View VLS and log
in as the administrator. See “Opening a Command View VLS Session from a Web
Browser” on page 105.
7. Select the System tab.
8. Select Nodes from the navigation pane.
9. Select Add Node from the task bar in the main window. This will bring up the Add Node Wizard.
10. Verify that the node name in the Node Name field is the next available number that you configured
previously. For example, the primary node, previously configured as Node 0, is identified as
Node 0 in the list of nodes on the navigation pane. The first secondary node added should be
Node 1. The next secondary node added should be Node 2.
11. Select Finish to add the node.
12. Repeat these steps to add nodes until all of the nodes are listed in the navigation pane.
NOTE:
Node numbering must be sequential with no gaps. Gaps in ID numbering will prevent the VLS from
recognizing any nodes with an ID after the gap. For example, if node numbering is 0, 1, 2, 4, 5, the
VLS will not recognize nodes 4 and 5.
NOTE:
When a VLS12000 node is used as a secondary node on a VLS300, the secondary node is installed
in compatibility mode.
Multi-node Setup34

4 Storage Configuration
This section describes how to configure the storage after the nodes have been configured.
Establishing Communication Between the VLS12000 Gateway
and the EVA
This section describes how to establish communication between the VLS12000 Gateway and the EVA
by adding hosts and ports to the EVA and then presenting the LUNs.
Verifying Array Zoning
Verify that you have configured the zoning between the EVA ports and all storage ports on all the
nodes of your VLS Gateway. For example, storage ports 2 and 3 on each node should connect to
different SAN zones/fabrics; EVA controllers should also be connected to both zones/fabrics. If you
have not done so, refer to the HP StorageWorks VLS and D2D Solutions Guide to do so now.
Presenting the LUNs
NOTE:
If you have noted the list of WWPNs while performing the multi-node setup (see “Configuring the
Secondary Nodes 1 through 7” on page 33), go directly to step 2 of the procedure below.

3. Present the LUNs:
CAUTION:
Present only the disks that you wish to use with the VLS Gateway because existing data will
be destroyed during storage pool configuration.
a. In Command View EVA, in the Storage tab navigation tree, select the EVA for the VLS
Gateway storage system, Virtual Disks, the disk name that you want to present, then ACTIVE
under that disk.
b. Select the Presentation tab.
c. Ensure that Write Protect is set to No.
d. Ensure that the Preferred path/mode is set to either Path A-Failover only or Path B-Failover
only (Figure 10).
NOTE:
Set the Preferred path/mode for half of the disks to Path A-Failover only, and to
Path B-Failover only for the other half of the disks. This balances the data traffic across
both A and B controllers. For more information on data traffic balancing, see “Array
Dual Pathing” on page 141.

e. Click on Present, then select the VLS Gateway host (just created) on the Present Vdisk screen
on the status pane.
f. Click on Present Vdisk.
g. The Operation Succeeded message displays on the status pane. Click OK.
h. Repeat these steps for each disk to present to the VLS.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 39
Page 40
NOTE:
If needed, these disks can be unpresented. See Deleting Array LUNs. If you unpresent
a LUN, you must then reconfigure the LUN numbering for all LUNs on the VLS Gateway
that follow the unpresented LUN in sequential numbering.
Managing VLS12000 Gateway Capacity
There are several ways to manage the capacity of your Gateway system:
• Add external LUNs to the VLS Gateway configuration. See Discovering Array LUNs.
• Delete external LUNs from the VLS Gateway configuration. See Deleting Array LUNs.
• Create storage pools. See Configuring Storage Pools.
• Destroy storage pools. See Deleting Array LUNs
• Enable device-side data compression when creating new tape drives. See “Creating Tape
Drives” on page 132
Discovering Array LUNs
1. Discover the LUNs, either by rebooting the entire VLS Gateway or:
a. Open a Command View VLS session and log in as the administrator. See “Opening a
Command View VLS Session from a Web Browser” on page 105.
b. In the Storage tab navigation tree, select Storage LUNs.
c. Select Discover Unconfigured Storage from the task bar. This causes the VLS to recognize
all presented LUNs and return the following message: # storage lun(s) discovered.
# storage lun(s) deleted. At this point, the LUNs are still unconfigured.
Storage Configuration40
Page 41
2. Verify that the LUNs are properly assigned and that there are two data paths for each LUN.
a. Open a Command View VLS session and log in as the administrator. See “Opening a
Command View VLS Session from a Web Browser” on page 105.
b. In the Storage tab navigation tree, select Storage LUNs.
c. Under All, select All Nodes in the Nodes dialog box, then click View to display Storage LUN
Details and Storage LUN Details Per Node (Figure 11).
Figure 11 Storage LUNs details window
.
d. Ensure that all LUNs are listed under each node, and that each has a preferred and secondary
path.
NOTE:
If a LUN is not recognized by each node, the LUN is unusable. Present the LUN to any
node that does not yet recognize the LUN.
3. Resolve any errors, if necessary.
If there is a license violation, you can still view all the LUNs. Either install more licenses or remove
the LUNs that do not belong. This will eliminate the violation. See Deleting Array LUNs.
Deleting Array LUNs
CAUTION:
Deleting an EVA LUN that is part of an existing storage pool will result in the loss of all cartridge data
for that storage pool.
To remove a LUN from the device:
1. Unpresent the LUN to the VLS (see instructions below) or delete the LUN from the external array.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 41
Page 42
2. Restart emulations or reboot the device (see “Restarting VLS Device Emulations” on page 144 or
“Rebooting the System” on page 100).
3. Discover unconfigured storage (see Discovering Array LUNs). This deletes the removed LUNs
from the configuration.
To unpresent a LUN:
1. In Command View EVA, Storage tab navigation tree, select the EVA for the VLS Gateway storage
system, Virtual Disks, the disk name that you want to present, then ACTIVE under that disk.
2. Select the Presentation tab for the ACTIVE Vdisk.
3. Click on the Unpresent button.
4. Select the disk to remove from the host (Figure 12).
Figure 12 Unpresent Host(s) window
.
5. Click on Unpresent host(s).
6. Click OK from the confirmation dialog box.
7. Click OK under Operation Succeeded in the status pane.
8. If there is a break in numbering of the remaining LUNs, LUN numbers after the break must be
reconfigured. See “Multi-node Setup” on page 33 for detailed instructions.
CAUTION:
LUN numbering must be sequential with no gaps. Gaps in LUN numbering will prevent the VLS
Gateway from recognizing any nodes with any LUNs after the gap. For example, if LUN
numbering is 0, 1, 2, 4, 5, the VLS Gateway will not recognize LUNs 4 and 5.
Configuring Storage Pools
VLS automatically creates one storage pool. HP recommends that a single storage pool is used even
for multiple arrays. However, if additional pools are needed, you must create them. To do so:
Storage Configuration42
Page 43
NOTE:
The VLS Gateway can have either one storage pool for all LUNs, or one storage pool for each array.
Refer to the solutions guide for details.
1. Create a storage pool(s):
a. Open a Command View VLS session and log in as the administrator. See “Opening a
Command View VLS Session from a Web Browser” on page 105.
b. In the Storage tab navigation tree, select Storage Pools.
c. From the task bar, select Create Storage Pool. The Create Storage Pool Wizard is displayed.
d. Click Finish. CREATE STORAGE POOL COMPLETED is displayed.
e. Click Return.
f. If you are creating a separate storage pool for each array, repeat this process for each
storage pool.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 43
Page 44
2. Add the array LUNs to the storage pool(s).
a. Open a Command View VLS session and log in as the administrator. See “Opening a
Command View VLS Session from a Web Browser” on page 105.
b. In the Storage tab navigation tree, under Storage Pools, select a storage pool.
c. From the task bar, select Add External LUN. The Add External LUN Wizard is displayed.
NOTE:
This task does not appear if there are no licenses available.
d. From the list of available unconfigured LUNs, select the LUNs to add to the pool. (By default,
all LUNs are selected.)
NOTE:
View the World Wide Unique Lun ID on the storage LUN list (on the System screen) to
identify which LUNs are associated with each array.
e. Use the Format check box to indicate whether the selected LUNs are initialized (formatted)
when added to the pool.
NOTE:
Do not format the LUNs when manually creating previously existing pools after
performing a disaster recovery of the primary node. If you do not format the LUN, all
cartridge data in that pool is retained.
f. Click Finish to add the LUNs to the pool.
The pool is now ready to have cartridges created.
NOTE:
If you created storage pools on a LUN that already contained cartridges, update the Allocated Capacity
numbers. To do this, select Cartridges from the system navigation tree, then select View for the All
listing.
Destroying Storage Pools
Command View VLS allows you to destroy a specific storage pool or all storage pools.
NOTE:
If there are cartridges in the pool or pools when they are destroyed, emulations will restart. To avoid
this restart, delete all cartridges from the pool prior to deleting the pool. (see “Destroying
Cartridges” on page 138).
To delete a single storage pool:
Storage Configuration44
Page 45
1. Open a Command View VLS session and log in as the administrator. See “Opening a Command
View VLS Session from a Web Browser” on page 105.
2. In the Storage tab navigation tree, select the pool to delete (listed under Storage Pools).
3. From the task bar, select Destroy Storage Pool. The Confirm Destroy <storagepool name> window
is displayed (Figure 13).
Figure 13 Confirm Destroy Storage Pool window
.
4. Select Next to destroy the pool.
A second page of the Confirm Destroy <storagepool name> screen is displayed, containing the
following text: WARNING: Existing data in StoragePool # will be destroyed and cannot be re-
covered. This step cannot be reversed.
5. Select Finish to display the screen confirming that the storage pool has been destroyed.
6. Select Finish again to return to the system screen.
You can now either use the LUNs previously assigned to the destroyed pool in other pools, or
they can be deleted.
To delete all storage pools:
1. Open a Command View VLS session and log in as the administrator. See “Opening a Command
View VLS Session from a Web Browser” on page 105.
2. In the Storage tab navigation tree, select Storage Pools.
3. If you wish to destroy all storage pools, from the task bar, select Destroy All Storage Pools. The
Confirm Destroy All Storage Pools screen is displayed.
4. Select Next to destroy the pools.
Either recreate storage pools using the LUNs previously assigned to the destroyed pool(s), or
delete them.
Installing Additional Licenses
Your VLS system may require any of the following licenses:
• Capacity — when you have added capacity to the system's base capacity.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 45
Page 46
A VLS capacity license must be installed on the VLS when storage exceeds the base license.
If you are in a license violation state, all VLS read/write operations are disabled until either sufficient
licenses are installed to support the storage, or the excess storage is removed. When you have
cleared a license violation by installing an upgrade capacity license, the VLS read/write operations
are automatically enabled without requiring a reboot.
Unconfigured VLS12000 Gateway array LUNs are counted by the system; therefore, they can
contribute to license violations.
• Deduplication — when you have upgraded to firmware version 3.1.x or higher to use the dedu-
plication feature.
A VLS deduplication license must be installed on the VLS before you can use the deduplication
feature. The number of deduplication licenses must match or exceed the number of capacity licenses
installed. After you install the deduplication licenses, the VLS system automatically enables the
deduplication feature for all supported backup types.
• Replication — when you have upgraded to firmware version 3.2.x or higher to use the deduplic-
ation-enabled replication feature.
A VLS replication license must be installed on the VLS before you can use deduplication-enabled
replication. Without the license, you may replicate backups across the SAN or LAN/WAN.
However, you need the replication license to replicate backups that have been deduplicated.
Deduplication-enabled replication requires one license per node on the target site.
Follow these steps to install capacity, deduplication, and replication licenses:
1. Use Command View VLS to obtain the VLS system serial number from the Identity tab.
2. Locate the paper or email entitlement certificate for the licenses you purchased. (You selected the
delivery method during the ordering process.)
HP recommends purchasing electronic certificates over physical certificates for faster delivery
and the convenience of not having to manage (either file away or throw away) confidential paper
certificates.
3. Log on to http://www.webware.hp.com.
4. Select Generate Licenses.
5. Sign in. If you are a new user, follow the on-screen instructions.
6. Enter the order number from the entitlement certificate.
7. Enter the VLS serial number. You will receive a license key immediately onscreen and via email.
8. Copy the license key.
9. Complete the installation in Command View TL. See the HP OpenView Command View for TL
User Guide for instructions.

5 Automigration/Replication
Instead of the preferred method of copying virtual media to physical media via the backup application,
another option is to perform transparent tape migration via the VLS device using automigration.
Automigration describes the feature in which the Virtual Library System acts as a tape copy engine
that transfers data from virtual cartridges on disk to a physical tape library connected to the VLS
device. The VLS automigration feature supports two different schemes:
• Echo copy automatically synchronizes the physical cartridges to matching virtual cartridges (with
the same barcodes) based on user-defined policies, and is totally transparent to the backup application.
• Using smart copy, the automigration process is under the control of the backup application,
managed via the VLS SMI-S interface. This requires the backup application to support the HP smart
copy interface.
You can also copy virtual media using replication. Replication provides automigration from the source
VLS across the LAN/WAN to a remote virtual destination library. See “Replication
Concepts” on page 49.
This section describes automigration topics from overall automigration concepts to specific operations
you can perform on your system.
NOTE:
Throughout the automigration windows, a
to the source library through the SAN and uses the automigration feature. A
to a remote destination library that is connected to the source through the LAN/WAN and uses the
replication feature.
NOTE:
When a list of slots is displayed, the message, “[#] items found, displaying 1 to 20.” appears. If there
are more than 20 items found, scroll through them using the arrows pointing right and left at the far
right-hand side at the top of the list. Also, in some cases, only available slots or only slots containing
tapes appear in the list.
NOTE:
For each procedure described in this chapter, at least one means of access to the relevant screen or
menu is specified. However, links are often provided in the main window that can be used as a
shortcut to other windows or menus.

Understanding Automigration Concepts
Before using automigration, review the information in this section. This will allow you to create copy
pools and automigration policies appropriate to meet your storage needs.
Echo Copy Concepts
Echo copy acts as a transparent disk cache to the physical library, so that the backup application
writes to virtual cartridges in the virtual library. Automigration then automatically schedules the copies
from virtual cartridges to physical cartridges with matching barcodes, based on the automigration
policies the user establishes.
Echo copy is managed through the automigration software, not the backup application. For that
reason:
• The destination library is not visible to the backup application, so it does not need licensing.
• Copy traffic is no longer routed through the SAN.
• All destination tapes created by echo copy are in the native tape format, so they can be restored
directly from any tape drive or library that is visible to the backup application.
When determining whether to use echo copy pools, remember:
• The backup application will not be aware of any copy failures.
• Any mistakes in destination library media management will also affect the virtual cartridges. For
example, if new tapes are not loaded into the destination library, the physical copy will not exist.
• The destination library can only be used for copy operations.
• Echo copy is a full tape copy, rather than an incremental change copy, so it can be an inefficient
use of media if you are using non-appending copy pools in your backup jobs.
An echo copy pool is used to define which destination library slots are to be echoed into a specified
virtual library. Automigration then monitors the echo copy pool slots to detect cartridge loads/ejects
in the destination library, and automatically synchronizes the virtual cartridges to the destination
cartridges, creating the matching virtual cartridges as needed.
This means that when new destination tapes are loaded, automigration will automatically scan them
(read the backup application headers) and then automatically create matching virtual cartridges in
the virtual library specified for that echo copy pool.
NOTE:
The automatic scanning of new cartridges can take a long time if all the tape drives in the destination
library are busy with higher priority operations such as copies. Therefore, it is best to load new tapes
when copies are not running.
Data written to echoed virtual cartridges will be automatically copied onto matching destination tapes
based on the echo copy policy. An echo copy policy defines for each source virtual library the copy
window (start and end times), the copy on eject option, and the time in days for expiration after eject.
If destination tapes are ejected, the matching virtual tapes are automatically moved to the firesafe
and are deleted at the policy-defined expiration time. This ensures the device does not fill up its disk
space with older cartridges. See “Creating an Echo Copy Pool” on page 55 to create a policy. If
virtual tapes are ejected by a backup application, the matching destination tapes are also automatically
ejected into the destination library mailslot when the copy operation is complete. When an echo copy
is ejected (mailslot eject box is checked), the echo copy is performed, then the eject is carried out.
This results in the echo copy being placed in the device's firesafe and maintained according to the
Automigration/Replication48
Page 49
established policy. If a destination tape was ejected while a copy was pending, then notifications in
the VLS GUI will inform the user that they have interrupted the copy process.
Smart Copy Concepts
Smart copy allows the backup application to trigger copies from virtual cartridges to destination
cartridges, and the VLS then performs that copy inside the device. The backup application can only
use this feature if it supports the HP smart copy mechanism (via SMI-S v1.3 or later copy services).
Keep in mind the following when determining whether to use smart copy pools:
• The destination library is not visible to the backup application.
• Copy traffic is no longer routed through the SAN.
• All destination tapes created by smart copy are in the native tape format, so they can be restored
directly from any tape drive or library that is visible to the backup application.
• Because the copy jobs are initiated from the backup application, the backup application will be
aware of any copy failures.
• The destination library can only be used for copy operations.
A smart copy pool is used to define which destination library slots are available as SMI-S copy targets
for a specified source virtual library. Smart copy pools automatically detect all tapes in the destination
library slots that are assigned to that pool. Destination tapes are unrelated to virtual cartridges – that
is, they have different barcodes and headers. Smart copy jobs are initiated by the backup application
using SMI-S V1.3 software, and the VLS then performs the specified copy (for example from a virtual
cartridge to a destination cartridge, or from a destination cartridge back to a virtual cartridge, etc.).
The backup application tracks the virtual cartridges and the destination cartridges separately since
they have different barcodes and potentially different contents.
NOTE:
When smart copy jobs are triggered, they can override (reschedule) lower priority jobs, such as echo
copy jobs, up to the maximum number of tape drives allocated to their smart copy pool. If you configure
both smart copy pools and echo copy pools on the same VLS, it is advised that some destination
library tape drives remain unallocated to smart copy pools so that echo copy operations can still
continue while smart copy is active.
Replication Concepts
Replication provides automigration via LAN/WAN between two VLS devices. Because replication is
a feature of automigration and uses the same Echo Copy policies that allow flexible cartridge/slot
based configuration, any number of different replication configurations can be supported. You establish
a replication policy and echo copy pools using Command View VLS in the same way you set up
automigration with a destination library on the SAN.
NOTE:
The replication feature cannot use smart copy, only echo copy.
During replication, the source VLS copies data to the echo copy pools on a replication library that is
on the source. During the user-defined availability window, this replication library migrates data to
the destination library, known as the LAN/WAN replication target.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 49
Page 50
The following are two of many possible replication configurations:
• Data center to data center
Designate one VLS as the source and a second VLS as the destination. Configure the destination
VLS to present a LAN/WAN replication target that is visible to the source VLS. The source VLS
performs normal backups during the regular backup window, and during the availability window
the source virtual cartridges automatically migrate to matching virtual cartridges on the destination
VLS. The same configuration is also used in the other direction so there is a backup library and a
LAN/WAN replication target library on both devices.
• Branch office to a main data center
Divide a single destination target into multiple slot ranges to allow a many-to-one configuration
without needing a separate replication library for each branch office. In this way, the VLS replication can scale to hundreds of branch offices all replicating to a single large device.
Replication can be configured to operate in one of two modes:
• Deduplication-enabled replication — the virtual cartridge on the source VLS is deduplicated against
the virtual cartridge on the target VLS. In this manner, only data that has changed is transmitted
over the network to the target VLS. This mode requires that deduplication is licensed and enabled
on both the source and the target VLS.
• Whole cartridge replication — the entire virtual cartridge is copied from the source VLS to the
target VLS.
NOTE:
All of the information on automigration also applies to replication except where specifically dealing
with physical tapes (e.g., ejecting media) and where noted. Otherwise, where the information refers
to physical cartridges, for replication assume virtual cartridges instead.
NOTE:
Replication is deduplication-enabled if you have purchased the appropriate replication and
deduplication licenses, and your backup ISVs and data types are supported for deduplication. Check
the
Accelerated deduplication ISV support matrix
system supports deduplication.
Tape Initialization
When you first configure deduplication-enabled replication on your VLS and set up an echo copy
pool to a LAN/WAN destination, the first round of data migration is not deduplicated because there
is not yet a set of backups on the target VLS to deduplicate against. Because the first full set of backups
can be very large, the VLS system includes a tape initialization process. You can transport the first
full set of backups to the target VLS using physical tapes rather than the network. This tape initialization
process is optional and must be enabled by the administrator when creating the echo copy pool.
The tape initialization process works, very generally, like this:
1. Set up the LAN/WAN replication target on the remote site
2. Set up an echo copy pool on the source site
3. Run a standard deduplication backup on the source site
4. Export the full backup to physical tapes
at http://www.hp.com/go/ebs/ to see if your
Automigration/Replication50
Page 51
5. Transfer the physical tapes to the remote site
6. Import data from the tapes onto the remote LAN/WAN replication target
Once the tape initialization process is complete, the automatic migration of deduplicated data from
the source site to the target site over the LAN/WAN begins. See “Exporting Data to Physical tapes
for Tape Initialization” on page 78 and “Importing Data from Physical Tapes for Tape
Initialization” on page 79 for the specific procedures.
Connecting a Destination Library
Automigration requires one or more dedicated destination libraries to be connected to the VLS device.
Supported Destination Library Configurations
Automigration is supported on:
• HP MSL series tape libraries
• HP EML series tape libraries or library partitions
• HP ESL E-series tape libraries or library partitions
• HP VLS virtual libraries
Using automigration, you can share a single destination library across multiple virtual libraries
(maximum of 20 drives on the physical libraries), or configure multiple destination libraries to be used
in a single virtual library.
CAUTION:
Automigration only supports destination libraries that have homogeneous drive types; for example,
all drives are LTO-2. A mixture of drive types in the destination library, such as LTO-3 and LTO-2, is
not supported.
NOTE:
Automigration allows you to use a VLS as a destination library. Because of this feature, it can also
be used as a device-to-device local replication scheme.
Connecting a Destination Library to the VLS12000 Gateway
To connect the destination library to a Gateway device:
1. Connect your destination library to the VLS Gateway by connecting the library into the existing
SAN zone that contains the arrays for this device.
2. Reboot the VLS. Upon reboot, the device detects the newly connected destination library.
Managing and Unmanaging a Destination Library
To manage a library is to enable automigration by connecting the source library to a destination
library that is already on the VLS. Until you manage the destination library, it cannot communicate
with the source. The process for managing destination libraries is different for SAN libraries than for
HP StorageWorks 12000 Gateway Virtual Library System User Guide 51
Page 52
LAN/WAN libraries. See “Managing a SAN Library” on page or “Managing a LAN/WAN Replication
Library” on page .
An unmanaged library is a library that is not recognized by and using automigration or replication.
The process for unmanaging destination libraries is the same for both SAN and LAN/WAN libraries.
See “Unmanaging a SAN or LAN/WAN Library” on page 53.
Managing a SAN Library
To manage a SAN library:
1. Open the Automigration/Replication tab.
2. From the task bar, select Manage SAN Automigration Library.
The screen displays all eligible libraries. Libraries that appear on the list but are greyed out either
have no drives or have multiple drive types and therefore cannot be managed. Also, if there are
no unmanaged drives, the system will return the message, “There are no unmanaged libraries.”
3. If the library you wish to manage is not already selected, select it now.
NOTE:
You can only select one library to manage at a time. To manage additional libraries, repeat
the procedure for each library to add.
4. Select Submit.
The Destination Library Details screen displays, with the message, “The library, [library name],
was managed successfully.”
You can now create pools for the library and manage your data on the library using automigration.
You can also unmanage the library at any time. See “Unmanaging a SAN or LAN/WAN
Library” on page 53 for instructions.
Managing a LAN/WAN Replication Library
To manage a LAN/WAN replication target:
1. Select the Automigration/Replication tab.
The Summary for All Managed Destination Libraries screen displays.
2. Select Manage LAN/WAN Replication Library from the task bar.
3. Enter the name or IP address of the host containing the LAN/WAN replication target you just
created.
4. Select Submit.
5. On the next screen, select the LAN/WAN replication target to manage.
6. Enter the password you created for that target.
7. Select Submit.
The LAN/WAN replication target is now associated with the source.
You must re-manage a LAN/WAN replication target if you change the password for security reasons.
To re-manage a LAN/WAN replication target:
Automigration/Replication52
Page 53
1. Select the Automigration/Replication tab.
2. Expand Destination Libraries in the navigation tree.
3. Select the library of interest to open the Destination Library Details screen.
4. From the task bar, select Re-manage LAN/WAN Replication Target.
5. Enter the host name of the LAN/WAN replication target only if the LAN/WAN replication target's
host name has changed.
6. Enter the LAN/WAN replication target password.
7. Select Submit.
The LAN/WAN replication target is now re-managed with the source using the new password.
You can now create pools for the library and manage your data on the library using replication.
You can also unmanage the library at any time. See “Unmanaging a SAN or LAN/WAN
Library” on page 53 for instructions.
Unmanaging a SAN or LAN/WAN Library
Use one of the following two ways to unmanage a library:
Unmanage a library from the Destination Library Details window.
1. From the navigation tree, select the specific library to unmanage.
NOTE:
You can only select one library to unmanage at a time. To unmanage additional libraries,
repeat the procedure for each library to unmanage.
2. Select Unmanage from the task bar.
3. Select OK from the dialog box.
The Destination Libraries window displays and provides the message, “The library, [library name],
was unmanaged successfully.”
Unmanage the library from the Destination Libraries window.
1. Select Destination Libraries from the navigation tree.
2. From the task bar, select Unmanage Library.
The Unmanage Destination Library screen displays, showing all managed libraries. If there are
no managed libraries, the system will return the message: “There are no managed libraries”.
3. If the library you wish to unmanage is not already selected, select it now.
NOTE:
You can only select one library to unmanage at a time. To unmanage additional libraries,
repeat the procedure for each library to unmanage.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 53
Page 54
4. Select Submit.
The Destination Library Details screen displays, with the message, “The library, [library name],
was unmanaged successfully.”
Echo Copy Pool Operations
Echo copy acts as a transparent disk cache to the physical library, so that the backup application
writes to virtual cartridges in the virtual library. Automigration then automatically schedules the copies
from virtual cartridges to their matching physical cartridges (with the same barcodes) based on the
automigration policies.
For creating echo copies, automigration supports the following backup software on the physical
libraries:
• CA ARCserve Backup
• Commvault Galaxy
• HP DataProtector
• HP DataProtector Express
• Legato Networker
• Tivoli Storage Manager
• Veritas Net Backup
• Veritas Backup Exec
CAUTION:
Automigration does not support tar formatting. A tar file will not load if the first file on the tape is
larger than 1 MB unless you perform a Load for Restore. HP strongly recommends against using
automigration with tar-based backup software.
After connecting your destination library to the VLS and adding it as a Managed Library, follow these
steps to operate echo copy:
1. Identify the Virtual Library you will associate with this managed library.
2. Create an echo copy pool between the virtual library and this managed library.
Any cartridges loaded (or already present) in the managed library will be automatically detected,
and matching virtual cartridges will be automatically created in the associated virtual library.
NOTE:
The automatic scanning of new cartridges can take a long time if all the tape drives in the
destination library are busy with higher priority operations such as copies. For this reason,
it is best to load new tapes when copies are not running.
3. Check for the auto-created virtual cartridges in the virtual library. On the Automigration/Replication
tab, expand Source Cartridges in the navigation tree and then select the library of interest. The
screen displays the cartridges created by automigration.
4. Any data written to the automigration virtual cartridges will be automatically mirrored onto the
matching destination tapes based on the automigration policy settings. Monitor the status of the
mirror by using a Command View VLS Console and viewing the destination tapes in Slots in the
expanded list under Destination Library.
Automigration/Replication54
Page 55
5. In order to restore from a destination cartridge, either load it into a physical drive that is visible
to the backup application, or perform a Load for Restore. Load for Restore copies the destination
tape back into the virtual cartridge so that the backup application can then restore from the virtual
cartridge.
Creating an Echo Copy Pool
Echo copy pools are created from physical library slots after a destination tape library is added to
the VLS automigration configuration. Each echo copy pool defines:
• The single destination library
• The single source virtual library
• The slot range
• The echo copy pool policy
Each virtual library has a SAN policy, and those used as a replication library will also have a
LAN/WAN policy. These policies are set up during the creation procedure.
To create an echo copy pool:
1. On the Automigration/Replication tab, expand Destination Libraries on the navigation tree so
that you can see all the related items.
2. Expand the destination library for which you want to create a pool.
3. Select Copy Pools on the navigation tree.
4. From the task bar, select Create Echo Copy Pool.
The CREATE ECHO COPY POOL screen displays.
5. Enter a start slot number and an end slot number for the copy pool from within the available slot
range shown.

Initialization” on page 50.)
10. Select Next Step to set the policies.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 55
Page 56
11. Type the desired policy settings in the corresponding fields. The policy settings differ for SAN
libraries and LAN/WAN libraries, and are as follows:
SAN libraries:
• Retention days – the number of days information is kept in the firesafe before it is deleted.
The default is two days.
• Sizing factor – the percentage of space, compared to the actual size of a disk, allocated on
the virtual tape for the copy job. For example, if the sizing factor is set to 90% and the
physical tape is 100 GB, the allocated space for the virtual tape will be 90 GB.
NOTE:
The sizing factor is crucial to creating the right size virtual tapes. When determining the sizing
factor of the virtual tapes, keep in mind the following:
• The sizing factor should be based on the size of the physical tape or the tape type if
possible. Common tape types and their sizes are: LTO-1 – 100 GB, LTO-2 — 200 GB,
LTO-3 — 400 GB, LTO-4 — 800 GB, DLT-IV — 80 GB, DLT-VS1 — 160 GB, SDLT-I —
320 GB, SDLT-II — 600 GB.
• HP recommends against setting the sizing factor too high (for example 110%). Although
the virtual copy can be made, if the drive compression is too low the data might not fit
back onto the physical tape.
• The sizing factor applies to all operations except Load for Restore, in which case the sizing
factor is ignored and the virtual copy is exactly the size of the physical cartridge.
• In general, the virtual cartridge is approximately 90% of the actual cartridge size. Base
the size of the copy on the eventual maximum size of the actual cartridge that is to be
copied.
• Source cartridge size limit — the size of all newly created source cartridges, regardless of
the physical cartridge size, on VLS systems with deduplication enabled. The default size is
200 GB; the maximum size is 300 GB.
Certain operations, such as loading physical cartridges into a copy pool with pre-existing
source cartridges, will require you to accept resizing the existing cartridges if they exceed
the size limit set here. In this case, a warning message indicates the number of cartridges to
be resized if you proceed. If you opt to continue and resize the source cartridges, no data
will be lost; you can still access data beyond the end of the newly set capacity limit.
The Sizing Factor also controls the size of the source cartridge. The system will size the source
cartridge using the Source cartridge size limit or the sizing factor, whichever value is the
smallest.
• Echo Copy on Source Cartridge Eject – When the backup application ejects an out of sync
virtual cartridge, the matching destination cartridge will not be ejected until the copy is complete. When the copy on eject option is not checked, then the time to complete the copy and
eject the destination cartridge will depend on your start time and window size. When this
option is checked, then the copy will be started as soon as possible (depending on available
drives) regardless of start time and window size. Then the destination cartridge will be ejected.
• Send notification if cartridge not migrated in — the copy pool threshold. The system will send
a notification if this many hours have passed and the cartridges have not migrated.
• Start mirror of Out of Synch cartridges — When a cartridge goes into the ‘Out of Sync’ state,
you can schedule the mirror operation to begin only at the start of the policy window, or to
wait for the specified number of hours to pass after it enters the ‘Out of Sync’ state (provided
the time is within the policy window). The default is to schedule mirror jobs immediately upon
entering the ‘Out of Sync’ state provided the current time is within the policy window. Set this
Automigration/Replication56
Page 57
value to a number greater than zero to prevent aborted or multiple mirror operations on a
cartridge where the backup application mounts the cartridge, writes to it, unmounts the cartridge, and then repeats this cycle multiple times during a backup window.
• At End of the Policy Window – what happens to active jobs when the policy window is over.
The options are Allow Active Jobs to Complete, Cancel Active Jobs, and Cancel Active Jobs
if Less Than 0% complete. If you select the last option, enter the percentage completion in the
field.
LAN/WAN libraries:
• Priority — the priority this echo copy pool takes over other copy pools during the backup
window.
• Deduplication Timeout (only if you selected deduplicated replication on the previous screen)
— if the cartridge fails to deduplicate within the timeout limit you set, the entire cartridge is
copied over in non-deduplicated mode.
• Send notification if cartridge not replicated in — the copy pool threshold. The system will send
a notification if this many hours have passed and the cartridges have not replicated.
• Start mirror of Out of Synch cartridges — see above for LAN libraries.
• At End of the Policy Window – see above for LAN libraries.
12. Select Next.
13. Beneath the policy settings you just entered, enter the details of the window duration:
• Start Day – the day of the week on which the echo copy job begins. HP recommends that
copies are scheduled on a different day and/or time window from other backup activities.
• Start Time – the time at which the echo copy job begins. HP recommends that copies are
scheduled within a different time window from other backup activities.
• Window Duration – the number of hours available during which the echo copy job can take
place. If the migration does not take place during this window, the job is maintained in the
queue until the next start time.
For SAN destinations, HP recommends that you schedule mirror copies on a different day/time
window than backup activities. For LAN/WAN destinations, HP recommends that you allow
mirror copies to run 24 hours a day unless there is a need to restrict the use of LAN/WAN
bandwidth during certain periods of the day.
14. Select Add.
The window refreshes, and the availability window you just added is moved to the Current
Availability Windows section of the screen.
Repeat steps 12 through 14 for as many availability windows as you need.
15. If you need to delete an availability window you just created, select Delete corresponding to that
window.
16. Select Submit.
If the pool was successfully created, the Copy Pools screen displays, along with the message,
“The echo copy pool [echo copy pool name] was successfully created.”
If the pool was not created, the CREATE NEW ECHO COPY POOLS screen refreshes and provides
an error message at the bottom of the screen. Failure to create the pool most often occurs because
the slot numbers chosen are outside the available slot range. “The start slot is not in a free range
of slots” displays if only the start slot or both the start and end slots are out of range. “The end
slot is not in a free range of slots” displays if only the end slot is out of range.
17. If the new pool is not created due to a slot range error, repeat this procedure and select slots
within an available range.

Creating Virtual Tapes
Virtual tapes are created automatically when:
• A pool is created that includes physical tapes.
• A Load Media for Restore, Load Blank Media, or Load Media for Overwrite is performed.
• A tape is moved into an echo copy pool by some means other than automigration.
NOTE:
The tape is only created if a header exists and is legible by the system.
Restoring from a SAN Physical Cartridge
If the destination tape is still loaded in the destination library, then its matching virtual cartridge will
still be present in the virtual library. In this case, you can simply restore from the virtual cartridge using
the backup application.
If the destination tape has been ejected from the destination library, you must use one of the following
options:
1. If the automigration virtual cartridge still exists in the firesafe (for example, if the policy-defined
retention period has not expired), use Command View VLS to manually move the cartridge back
into the virtual library. You can then restore from the virtual cartridge using the backup application,
and then move the cartridge back to the firesafe.
2. If the automigration virtual cartridge has been deleted from the firesafe, retrieve the physical
cartridge by one of the following methods:
• Load the physical cartridge into any compatible physical drive or library that is visible to the
backup application and restore from that tape using the backup application.
• Load the physical cartridge into the destination library and perform a Load Media for Restore,
which copies the entire destination tape back into a virtual cartridge. You can then restore
from the virtual cartridge using the backup application.
To perform Load Media for Restore:
1. Select the Automigration/Replication tab.
2. In the navigation tree, expand Destination Libraries and then the library of interest.
3. Select Mailslot to display the list of mailslots on that library.
4. From the task bar, select Load Media for Restore to open the Load Media for Restore screen.
5. From the drop-down box, select the copy pool you want to load the media into. You can choose
among the echo copy pools.
6. For all mailslots, the destination slots are automatically populated with the first available slots.
To keep the automatic assignment, skip to Step 10. To assign the destination slots manually,
continue to the next step.
If the Destination Slot Number for each mailslot displays “None,” the copy pool you selected is
full. Select another copy pool and the Destination Slot Number column will show the automatic
assignment.
7. Click Clear All to clear the automatic assignments.
Automigration/Replication58

9. Hover over each Select Slot link until you have selected a destination slot for each mailslot.
10. Click Next Step. A confirmation screen displays.
11. Click Load. The Media Move History screen displays the current status of the move. The possible
status messages are Moving, Waiting, Successful, and Failed.
If the status of the move is still Moving or Waiting, you can click Cancel to stop the move.
Automigration will then automatically create a matching blank virtual cartridge in the source
virtual library defined for this echo copy pool if one does not already exist.
CAUTION:
Any tape moved into an echo copy pool in this way will be considered blank even if it contains data.
Loading Media into an Echo Copy Pool for Overwrite
To load an expired tape (a tape that was previously backed-up to and is being reused) from a mailslot
on a destination library into an echo copy pool, use Load Media for Overwrite. From Command View
VLS:
1. Select the Automigration/Replication tab.
2. In the navigation tree, expand Destination Libraries and then the library of interest.
3. Select Mailslot to display the list of mailslots on that library.
4. From the task bar, select Load Media for Overwrite to open the Load Media for Overwrite screen.
5. From the drop-down box, select the copy pool you want to load the media into.
6. For all mailslots, the destination slots are automatically populated with the first available slots.
To keep the automatic assignment, skip to Step 10. To assign the destination slots manually,
continue to the next step.
If the Destination Slot Number for each mailslot displays “None,” the copy pool you selected is
full. Select another copy pool and the Destination Slot Number column will show the automatic
assignment.
7. Click Clear All to clear the automatic assignments.
8. Hover over the first Select Slot link to display a pop-up box of the available destination slots.
Select a slot number from the box.
After you select a slot from the available destination slots, that slot no longer appears in the
pop-up box.
Automigration/Replication60
Page 61
9. Hover over each Select Slot link until you have selected a destination slot for each mailslot.
10. Click Next Step. A confirmation screen displays.
11. Click Load.
The Media Move History screen displays the current status of the move. The possible status
messages are Moving, Waiting, Successful, and Failed.
If the status of the move is still Waiting, you can click Cancel to stop the move.
Automigration will then automatically scan the header from the loaded tape when a drive becomes
available. The amount of time this takes varies depending on how busy the destination library
is. After scanning the tape header, it will automatically create a matching virtual cartridge (if one
does not already exist) in the source virtual library defined for this echo copy pool that is blank
except for the header written at the beginning of the tape.
NOTE:
Because no data has been stored, you cannot restore from this virtual tape.
Restarting a Broken Mirror
The “mirror broken” state can occur when there is not enough room on the virtual tape to create the
copy, there are no available slots to create the copy, the library cannot read the header of the physical
tape, the library cannot determine that a tape without a header is blank, or the library cannot
successfully write the header to the virtual tape.
When a physical cartridge in a destination library is in this state, you must restart the broken mirror
for the automigration to continue. The Restart Broken Mirror task triggers a job to run which clears
out the problem.
1. From the task bar, select Restart Broken Mirror. The Restart Broken Mirror screen opens and
displays all cartridges with the Mirror Broken status.
2. Select the cartridges you want to restart.
3. Select Submit. The Result screen indicates that the operation was successful. The cartridge is now
in the UpToDate status.
Viewing Cartridges in Automigration Source Libraries
When a tape is still present in the destination library, you can view the matching automigration virtual
cartridge in the associated source virtual library. To view cartridges in the source libraries:
1. On the Automigration/Replication tab, select Source Cartridges from the navigation tree.
2. The right hand pane then shows all the automigration virtual cartridges (alphabetically by bar
code) in the source libraries and information including the cartridge state, last written date,
destination library, and destination slot.
Viewing Automigration Cartridges in the Firesafe
When a cartridge is ejected from the destination library, its matching virtual cartridge is automatically
ejected out of the virtual library and moved into the device's firesafe. The firesafe acts as a virtual
offline location for the automigration virtual cartridges. Once they are in the firesafe, the automigration
HP StorageWorks 12000 Gateway Virtual Library System User Guide 61
Page 62
virtual cartridges are retained according to their automigration policies, which define how many days
the virtual cartridges remain in the firesafe before being automatically deleted.
NOTE:
From the Automigration/Replication tab of Command View VLS, the firesafe in the window shows
items placed in the firesafe by automigration only; items placed in the firesafe from different functions
of the VLS are not shown here.
To view cartridges in the firesafe, from the Automigration/Replication tab, select Firesafe from the
navigation tree. For mirror copies, the firesafe date is the date of the most recent copy.
When the physical tape is moved back into the physical library, the corresponding virtual tape is
immediately moved from the firesafe back to the appropriate location (based on the location of the
physical tape). The physical tape is not read upon load and is not synchronized to the virtual tape.
Therefore, if you have modified the physical tape while it was outside of the library, then it is now
out-of-sync with the virtual tape in the firesafe. If you want to keep these modifications to the physical
tape, you will need to ensure that the data is copied to the virtual tape. Either manually delete the
virtual tape from the firesafe or perform a Load Media for Restore. This forces the system to read the
physical tape upon load and causes automigration to create a new virtual copy. See “Restoring from
a SAN Physical Cartridge” on page 58.
Smart Copy Pool Operations
Smart copy allows the backup application to trigger copies from virtual cartridges to destination
cartridges, and the VLS then performs that copy inside the device. The backup application can only
use this feature if it supports the HP smart copy mechanism (via SMI-S v1.3 or later copy services).
Editing SMI-S Settings
SMI-S is the communications mechanism between the backup application and smart copy. If your
backup application supports smart copy, you will need to link your backup application to the device
SMI-S interface. This may require you to modify the device SMI-S security. See “SMI-S
Support” on page 153 for SMI-S information.
Creating a Smart Copy Pool
Smart copy pools are created from physical library slots after a destination tape library is added to
the VLS automigration configuration. Each smart copy pool defines:
• The single destination library
• The single source virtual library
• The slot range
• The pool mode – echo copy or smart copy
• The number of drives allocated to the pool (for smart copy only)
To create a smart copy pool:
1. Select the Automigration/Replication tab and expand the task bar of the navigation tree so that
you can see all the items listed under Destination Libraries.
2. Select Copy Pools on a destination library for which you want to create a pool.
Automigration/Replication62

3. From the task bar, select Create Smart Copy Pool.
The CREATE NEW SMART COPY POOL screen displays.
4. Select a start slot and an end slot for the copy pool from within the available slot range.
5. Select the number of drives to create within the pool. The number of available drives is displayed
just above the empty field.
6. Select the source library from the Local Library list.
7. Select Submit.
If the pool was successfully created, the Copy Pools screen displays, along with the message,
“The smart copy pool [smart copy pool name] was successfully created.”
If the pool was not created, the CREATE NEW SMART COPY POOLS screen refreshes and provides
an error message at the bottom of the screen. Failure to create the pool most often occurs because
the slot numbers chosen are outside the available slot range. “The start slot is not in a free range
of slots” displays if only the start slot or both the start and end slots are out of range. “The end
slot is not in a free range of slots” displays if only the end slot is out of range.
8. If the new pool is not created due to a slot range error, repeat this procedure and select slots
within an available range.
Changing the Number of Drives in a Smart Copy Pool
When there are not enough drives in a smart copy pool, add more. To change the number of drives
in a smart copy pool:
1. Select the Automigration/Replication tab and expand the task bar of the navigation tree.

3. From the SMART COPY POOLS table, select the copy pool of interest.
4. Select Change Drives from the task bar to open the CHANGE DRIVES FOR SMART COPY POOL
window.
5. Type the number of drives to assign to the smart copy pool in the appropriate field.
6. Select Submit.
The Copy Pools window displays, along with the message, “The number of drives for the smart
copy pool, [copy pool name], was successfully changed.”
Loading Blank Media into a Smart Copy Pool
To move a blank tape (or a tape that should be considered blank) from a MailSlot on a destination
library into a smart copy pool, use Load Blank Media.
1. From the navigation tree under the appropriate destination library, select MailSlot to display the
list of mailslots on that destination library.
2. From the task bar, select Load Blank Media.
3. From the LOAD BLANK MEDIA screen, select the source slot.

Changing the Slot Mapping for a SAN Library
Slot mapping refers to the assignment of physical slots in a library to correspond to a specific virtual
copy pool. Mapping occurs as a copy pool is created; however, mapping can be changed at any
time. Reasons to change the slot mapping include the need for a group of slots to expand to match
the corresponding virtual copy pool, the need to shrink an existing pool to make more room for a
growing pool, and the need to rearrange the mapping so that the pools correspond to a consecutive
set of slots.
To remove the slot mapping of any copy pool:
1. Select Slots in the appropriate library from the navigation tree.
2. In the Copy Pool column, select any instance of the appropriate pool.
The SMART COPY POOL DETAILS or ECHO COPY POOL DETAILS screen displays.
3. Select Delete in the taskbar.
4. Select OK from the dialog box.
The copy pool details screen refreshes and the message, “The slot map was successfully deleted
from [copy pool name]” displays.
NOTE:
If a tape is in a newly unmapped section of a library, the tape will be moved to the firesafe.
If the tape has not expired and been deleted from the firesafe, upon remapping of the
section, the tape will move back and be removed from the firesafe.
To add slot mapping to any copy pool which does not have slots mapped:
1. Under Destination Libraries, select Copy Pools from the navigator pane.
2. Select the appropriate copy pool to display the copy pool details screen.
3. From the task bar, select Edit Slot Maps.

and displays “The start and end slot define an invalid range.”
6. If the slot map is not changed due to a slot range error, repeat this procedure and select slots
within an available range.
Changing the Slot Mapping for a LAN/WAN Library
Slot mapping in the case of replication refers to the assignment of virtual slots in a library to correspond
to a specific LAN/WAN replication target. Mapping occurs as a LAN/WAN replication target is
created; however, mapping can be changed at any time. Reasons to change the slot mapping include
the need for a group of slots to expand the number of slots on the LAN/WAN replication target, the
need to shrink an existing LAN/WAN replication target, and the desire to rearrange the mapping
so that the LAN/WAN replication targets correspond to a consecutive set of slots.
To remove the slot mapping of any copy pool:
1. Select the Automigration/Replication tab.
2. Expand LAN/WAN Replication Libraries in the navigation tree, and then expand the appropriate

SAN Destination Library Operations
This section describe all of the SAN destination library operations available to the user.
Monitoring Destination Library Status
This section describes how to locate the Command View VLS automigration status messages of a
destination library. This applies to both SAN automigration libraries and LAN/WAN replication
libraries.
VLS hardware, environmental, and virtual device (library, tape drive, cartridge) status is constantly
monitored by the VLS software and displayed on the VLS web user interface, Command View VLS.
A notification alert is generated by the VLS software when a hardware or environmental failure is
detected or predicted. VLS notification alerts are displayed on the Notifications screen of Command
View VLS, and can also be sent as mail to the addresses you specify and/or as SNMP traps to the
management consoles you specify. Status is also provided, where appropriate, on some screens under
the Automigration/Replication tab.
To monitor the automigration status of a destination library:
1. Select the Automigration/Replication tab.
2. In the navigation tree, select the destination library to view. This opens the Destination Library
Details screen.
This screen displays the state of the destination library. For SAN automigration libraries the
options are Good, Degraded, Critical, Failed, or Missing; for LAN/WAN replication libraries
the options are Connected, Configuration Out of Sync, and Unreachable. The screen also provides
the name and model of the library, number of simultaneous transfers, number of slots, management
URL, and availability.
3. Expand the destination library in the navigation tree to access more specific information.
Cartridge Status and Slot Details
To view the status of the destination library's slots, expand the library in the navigation tree and select
Slots.
The Summary for Slots screen displays the drive name, barcode, cartridge status, local library, copy
pool, and last mirrored date for each slot number in use. Select a barcode from the list to see more
details on the job history and status for that barcode.
Quickly locate slots of interest using the Advanced Search. See “Advanced Search for
Slots” on page 71.
You can also select Slots State Summary from the navigation tree to see which of all the possible
statuses have slots in that status; if a status is not listed, there are no slots currently in that status. The
number of slots in each status is displayed. Select a status to see a list of the specific slots in that status.
The Cartridge Status column of the Summary for Slots screen is particularly useful with echo copy
because the backup application is not aware of any copy failures. The status of the physical cartridges
in the destination library will be one of the following:

LAN/WAN Destination Library Operations
The following sections describe the destination library operations for LAN/WAN libraries available
to the user.
Several operations also apply to SAN destination libraries and are explained in SAN Destination
Library Operations:
• “Monitoring Destination Library Status” on page 68
• “Placing a Library Offline or Online” on page 72
• “Forcing a Replication Job” on page 72
Exporting Data to Physical tapes for Tape Initialization
NOTE:
Before beginning the export process, verify that the physical tape library exporting the data uses the
same number of barcode characters as the physical tape library that will import the data. If the
barcodes do not match exactly, the import process will not work. See your tape library user manuals
for information on checking and configuring the number of barcode characters used.
1. Create a LAN/WAN replication target on the remote site. See “Creating a LAN/WAN Replication
Target” on page 80.
2. Create a virtual library on the source site. See “Creating a Virtual Library” on page 130.
3. On the source site, create an echo copy pool on the newly created LAN/WAN replication target.
See “Creating an Echo Copy Pool” on page 55. Be sure to check the “Initialize via Tape Transport”
box.
4. From the Copy Pools screen, select the newly created copy pool to open the Echo Copy Pool
Details screen. Note that the state of the copy pool is “Awaiting Initialization.”
5. Allow your regularly scheduled full backups to complete. Cartridges that need to be transported
via physical tape become “Out of sync.”
6. From the task bar, select Initiate Tape Transport. The Create Tape Export Pool screen opens.
7. From the SAN Automigration Library list, select the physical library from which you want to copy
the tapes.
8. Enter a Start and End Slot from the available slot range.
9. Select Submit. The status of the copy pool changes to “Exporting.”
10. From the navigation tree, select Import/Export Pools, and then select the newly created export
pool to see the Tape Export Pool Details screen.
The data from the selected library slots is copying to the physical tapes. When the data has
finished exporting to the tapes, the status of the copy pool changes to “Importing.” The screen
prompts you to load empty tapes and unload full tapes as needed.
11. Once the export is finished, select Import Handling Instructions from the task bar. This produces
information needed for the data import process. Print this information and ship it to the remote
location with the physical tapes.
Automigration/Replication78
Page 79
Stopping a Tape Export
1. On the navigation tree, expand Destination Libraries and select Import/Export Pools to open the
list of all import and export pools.
2. Select the export pool you wish to stop to open the Tape Export Pool Details screen.
3. From the task bar, select Stop Tape Export.
The export process stops immediately and all echo copy pool cartridges move to the “Out of
sync” state.
4. From the Echo Copy Pool Details screen, you can:
• Select Initiate Tape Transport in the task bar to restart the export.
• Select Cancel Tape Transport in the task bar to cancel the process and place the echo copy
pool into the “Ready” state.
Importing Data from Physical Tapes for Tape Initialization
1. Complete the export process. See “Exporting Data to Physical tapes for Tape
Initialization” on page 78.
2. On the target site, open the Automigration/Replication tab and select Import Tapes from the
navigation tree.
3. Select the export pool you want to import.
4. From the Local Library list, select the physical library from which to copy the tapes.
5. Enter the start and end slots from the available slot range.
6. Select Submit.
7. Select Import/Export Pools from the navigation tree, then select the newly created import pool
to see the Tape Import Pool Details screen.
The screen prompts you to load full tapes and unload finished tapes as needed. If a physical
tape is damaged or otherwise unavailable, you can select Skip for that tape and transmit the
data over the LAN/WAN after the import process completes.
8. After the import process completes:
• The tape import pool is automatically destroyed on the target site
• The tape export pool is automatically destroyed on the source site
• The echo copy pool on the source will change to the “Ready” state and deduplication-enabled
replication over the LAN/WAN will begin at the next screen
Forcing Non-Deduplicated Replication
For systems using replication with deduplication, the Non Deduplicated Copy task allows you to
schedule a replication job that forces the whole cartridge (non-deduplicated data) to replicate
immediately regardless of whether or not the cartridge is within the policy window. You can only
perform this task when the cartridge is holding in the Backup Postprocessing state.
In Command View VLS:
1. On the Automigration/Replication tab, expand the destination library in the navigation tree and
select Slots to open the Summary for Slots screen.
2. Select Non Deduplicated Copy from the task bar.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 79
Page 80
3. On the Non Deduplicated Copy screen, select the slots you want to replicate.
4. Select Submit.
The system immediately registers the selected cartridges into the queue to replicate the whole
cartridge when resources are available regardless of the policy windows.
NOTE:
The whole cartridge copy of the data will not deduplicate. This data will consume additional space
on the target VLS until the cartridge is overwritten with new data by the backup application.
Pausing, Resuming, and Canceling Replication Jobs
Each replication job is actually split into smaller jobs: Mirror Preprocessing (preparing to move data),
Mirror (moving the data), and Mirror Postprocessing (clean-up process). This saves resources because
each job type uses only the resources it needs instead of reserving resources for the entire job. (Whole
cartridge replication is not divided into smaller jobs.) The source VLS displays the Mirror Preprocessing
and Mirror jobs, while the target VLS displays the Mirror and Mirror Postprocessing jobs.
From Command View VLS, select the Automigration/Replication tab, then select Job Reporting in the
navigation tree. This opens the Current Status screen where you can control the jobs.
On the source VLS, you can pause Mirror and Restore jobs and resume them at a later time, for
example when there are more resources available. At any point during the job, click the Pause Job
icon ( ) in the Action column. The job pauses, and the Pause Job icon is replaced by the Resume Job
icon ( ). When you are ready, click the Resume Job icon and the job will continue where it left off.
You can cancel all job types at any point by clicking the Cancel Job icon ( ) in the Action column.
NOTE:
When a replication library goes offline, all active mirror jobs pause. When the replication library
comes back online, all paused jobs resume.
LAN/WAN Replication Target Operations
The following sections describe the operations for LAN/WAN replication target.
Creating a LAN/WAN Replication Target
The first step in configuring replication is the creation of the LAN/WAN replication target. Do this
via Command View VLS on the destination VLS. Any virtual library (or slot range within a virtual
library) can be configured to act as a LAN/WAN replication target.
1. In Command View VLS, select the Automigration/Replication tab.
2. Expand LAN/WAN Replication Targets in the navigation tree.
Automigration/Replication80
Page 81
3. If the library on which you want to add a LAN/WAN replication target appears in the list, select
that library. The Summary for all LAN/WAN Replication Targets screen displays all LAN/WAN
replication targets created for that library.
If the library does not appear in the navigation tree, it means that the library does not yet have
any LAN/WAN replication targets on it. Select LAN/WAN Replication Targets in the navigation
tree instead. The Summary for All LAN/WAN Replication Targets screen displays all LAN/WAN
replication targets created for all libraries.
4. Select Create LAN/WAN Replication Target from the task bar to open the Create LAN/WAN
Replication Target screen.
5. Enter a name for the LAN/WAN replication target.
6. If you did not select your library from the navigation tree, select the library on which you want
to add the target from the Local Library menu.
The Available Slot Ranges section indicates the slots that are available on the library you just
selected.
NOTE:
If you selected your library from the navigation tree, this pull-down field does not appear
because you have already selected the appropriate library.
7. Enter a start slot and an end slot for the copy pool from within the available ranges.
8. Enter the number of maximum simultaneous transfers permitted.
This allows you to limit the replication activity on that target. This field defaults to the maximum
number of transfers allowed by the VLS.
9. Select a Compress option from the pull-down field.
The options are Global Setting, Yes (compression is on), and No (compression is off). See “Setting
the Global LAN/WAN Replication Target Configuration Settings” on page 82 to set the global
default.
10. Enter a registration password, and then retype it in the next field.
11. Select Add Availability Windows to open a new screen.
This takes you to a new screen.
12. In the Add Availability Window section of the screen, select the day and enter the time the
replication process should begin.
13. Enter the allowable duration of the replication jobs in hours and minutes.
Replication jobs can only begin during the availability window. When the availability window
ends, any replication jobs currently in progress will continue until they complete. No replication
jobs can begin until the next availability window opens.
14. Select Add.
The window refreshes, and the availability window you just added is moved to the Current
Availability Windows section of the screen.
Repeat steps 12 through 14 for as many availability windows as you need.
15. Select Submit.
The screen returns to the selected library's list of LAN/WAN replication targets.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 81
Page 82
16. Assign the LAN/WAN replication target to the source library. See “Managing a LAN/WAN
Replication Library” on page 52.
NOTE:
When you configure a virtual library as a LAN/WAN replication target with Echo Copy, you may
also need to hide it (e.g., using LUN masking or port mapping/zoning) from the front-end SAN in
the case where the same backup application instance sees both the source and destination VLS devices.
(The backup application must not see the same tape barcode in two places at the same time.) See
“LUN Mapping (v3.x)” on page 123 for details.
Viewing the Replication Target Slot Details
On the navigation tree, select Slots from the expanded replication target list to view the replication
target slots. The screen displays the barcode and last successful echo copy for each slot.
The last successful echo copy is intended to notify you of problems with the echo copy, but is not
necessarily related to the Cartridge Status or Last Mirrored fields on the Summary for Slots or Summary
for Cartridges screens. The state can be “unknown” when only the header transferred to the tape,
when nothing transferred to the tape, during the transfer of data, or when a data transfer has failed.
Setting the Global LAN/WAN Replication Target Configuration Settings
1. Select the Automigration/Replication tab.
2. Select Global LAN/WAN Replication Target Settings from the navigation tree.
3. In the Maximum MB/s per Active LAN/WAN Replication Transfer field, leave it set to Unlimited
or select the empty field and enter the total number of transfers that you will allow at one time.
4. From the Default Compression Setting for LAN/WAN Replication Targets menu, select whether
the compression for LAN/WAN replication targets is on (Yes) or off (No) by default.
5. Enter a new port number for unencrypted data transfer only if you need to change it from the
default.
Your firewall may require that the data transfer use a different port number.
6. Select Submit.
Editing a LAN/WAN Replication Target
To edit the LAN/WAN replication target settings:
1. Select the Automigration/Replication tab.

Availability Windows section of the screen.
4. To add a availability window, enter the information in the Add Availability Window section of
the screen, and then select Add.
Repeat this step for as many availability windows as you need.
NOTE:
When adding multiple availability windows, you must select Add for each new availability
window or the system will not record it.
5. Select Submit.
Deleting a LAN/WAN Replication Target
1. Select the Automigration/Replication tab.
2. Expand LAN/WAN Replication Targets on the navigation tree.
3. Select the LAN/WAN replication target you wish to delete.
4. On the LAN/WAN Replication Target Details screen, select Delete on the task bar.
5. Select OK from the dialog box.
The LAN/WAN Replication Targets screen displays with the deleted target removed from the list.
Changing the LAN/WAN Replication Target Password
You may need to change the LAN/WAN replication target's password in the event of a security
breach. The following steps will stop all communication between the source and the target, and then
re-establish secure communication.
1. Change the password on the LAN/WAN replication target.
See “Editing a LAN/WAN Replication Target” on page 82 to reach the Edit LAN/WAN Replication
Target Settings screen. Enter a new password for the target.
2. Change the LAN/WAN replication target's password on the source to the new password.
See “Managing a LAN/WAN Replication Library” on page 52 to reach the Re-manage LAN/WAN
Library screen. Enter the same password you just created for the target.
Clearing the Source VLS from the LAN/WAN Replication Target
You may want to clear the connection between a source library and its LAN/WAN replication target
in order to use the target with a different source library. The target library maintains all of its default
settings in the change.
On the destination library:
1. Select the Automigration/Replication tab.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 83
Page 84
2. Expand LAN/WAN Replication Targets on the navigation tree.

task bar.
5. The screen refreshes, and a message indicates that the connection has been cleared.
6. Connect the target with a different source library. See “Managing a LAN/WAN Replication
Library” on page 52.
NOTE:
Clearing the connection leaves both the source and destination libraries intact. This is different from
unmanaging a library, where the source library is deleted.
Automigration/Replication Reporting
The VLS stores job status and history for all automigration and replication jobs, allowing reports to
be generated and displayed online or exported in a comma-separated values (CSV) file format. You
can customize and view job status and history reports for the VLS automigration feature in Command
View VLS.
Cartridge Status
The Summary of All Cartridges Managed by Automigration/Replication screen provides a quick view
of the status of all cartridges that are managed by automigration/replication. Each managed cartridge
is counted among only one of the listed categories with the exception of the first category which can
contain cartridges listed elsewhere.
Echo Copy Pool Summary:
• Not migrated in Copy Pools threshold limit — contains cartridges that have not successfully mirrored
within the time threshold set for the echo copy pool (assigned in the policy when the echo copy
pool is created). A successful mirror is a cartridge that transitions from the “Backup Postprocessing”
state to the “Up to Date” state with several intermediate states. A notification is sent once a day
that identifies the number of cartridges that have not successfully mirrored within the threshold
time.
Cartridges in this category can also be listed in the following categories: Mirror Failed, Pending,
Mirror Active, In Use/Deduplicating, and Waiting for Policy Window. This category displays a
green (no cartridges in this category) or red (one or more cartridges in this category) icon.
• Mirror failed — corrective action needed — contains cartridges for which the copy to the mirror
has failed. This category displays a green (no cartridges in this category) or red (one or more
cartridges in this category ) icon.
• In Use/Deduplicating — contains cartridges that are currently being used by the system.
• Pending — contains cartridges that are ready for copy but have not started, for example, because
the system does not have enough resources available or because they are waiting for the dependent
cartridges to replicate.
• Paused — contains cartridges that have been paused.
• Waiting for policy window — contains cartridges that are waiting for the policy window to open
for replication to begin.
• Mirror Active — contains cartridges that are currently copying to the destination library.
Automigration/Replication84
Page 85
• Mirror Complete — contains cartridges that have completed copying to the destination library.
• Waiting for first backup — contains cartridges that do not yet have a stored backup.
• Initializing — contains cartridges that are currently initializing.
Target Copy Pool Summary:
• Mirror Active — contains cartridges that are currently copying to the mirror.
• Mirror Complete — contains cartridges that have completed copying to the mirror.
Use the Group By menu to filter the cartridge list, or click a particular category to view the summary
list of cartridges that it contains.
Cartridge Summary
Selecting a particular category from the Cartridge Status screen opens the Summary of <category>
Cartridges screen. The summary screen displays the cartridge barcodes and other information such
as the local library and destination library for each cartridge.
There are a number of tasks available in the task bar of the cartridge summary screens, and the tasks
displayed depend on the Cartridge Status category in which the cartridges belong.
• Copy Now — see “Forcing a Replication Job” on page 72.
• Non Deduplicated Copy — see “Copying the Whole Cartridge Outside of the Policy Win-
dow” on page 79.
• Refresh — refreshes the current screen.
• Restart Broken Mirror — see “Restarting a Broken Mirror” on page 61.
• Restore Media — see “Restoring from a LAN/WAN Virtual Cartridge” on page 59.
• Pause Job — pause one or more Mirror jobs. See “Pausing, Resuming, and Canceling Replication
Jobs” on page 80.
• Cancel Job — cancel one or more Mirror jobs. See “Pausing, Resuming, and Canceling Replication
Jobs” on page 80.
• Resume Job — resume one or more paused Mirror jobs. See “Pausing, Resuming, and Canceling
Replication Jobs” on page 80.
From the summary screen you can also click a specific barcode or an echo copy pool to see the
details of that selection.
Cartridge Details
View the details of a particular cartridge by clicking the barcode from the cartridge summary screen.
The details include the last time the cartridge was in the In Sync state, the current physical and logical
size, and the job history.
Some Cartridge Status categories provide a section of Additional Details on the cartridge details
screens. The additional details depend on the category. For example, cartridges in the Pending
category display a list of dependent cartridges while cartridges in the Out of Sync category display
whether or not the cartridge is ready to replicate.
You can export the details displayed on the screen to a text file by selecting Export Cartridge Details
in the task bar.
You can view the activity log of the cartridge, which lists the important events, operations, and state
transitions, by selecting View Log in the task bar. The list displays the most recent activity first. To
download the entire log file, select Export Log File from the task bar.

6 Deduplication
Deduplication is the functionality in which only a single copy of a data block is stored on a device.
Duplicate information is removed, allowing you to store more data in a given amount of space and
restore data using lower bandwidth links. The HP StorageWorks virtual library system uses Accelerated
deduplication.
NOTE:
The deduplication feature is only available on systems running VLS software version 3.0 or higher.
This section describes deduplication including getting deduplication running on your system, configuring
deduplication, and viewing reports.
NOTE:
See the
HP StorageWorks VLS and D2D Solutions Guide
for more detailed information.
How It Works
HP Accelerated deduplication compares the most recent version of a backup to the previous version
using object-level differencing code. It places pointers in the earlier version that identify duplicated
content in the new version. Deduplication then eliminates the redundant data in the earlier version
while retaining the complete, new version. You can improve deduplication performance simply by
adding additional nodes.
NOTE:
Deduplication takes place after the data has been processed to the backup tapes. Therefore, any data
backed up to compression-enabled virtual tape drives (both software and hardware compression) is
compressed before it is deduplicated.
The following is an overview of the deduplication process. See the HP StorageWorks VLS and D2D
Solutions Guide for more detailed information.
1. When a backup runs, a data grooming exercise is performed on the fly. Using meta-data attached
by the backup application, data grooming maps the content or “objects” of the backup, and
assembles a content database. This process has minimal performance impact.
2. After the scheduled backups have completed, the content database is used to “delta-difference”
(compare) objects in current and previous backups from the same hosts. There are different levels
of comparison. For example, files may be compared using a strong hashing function, while other
objects may be compared at a byte level.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 91
Page 92
3. When duplicate data is found in an older backup, it is replaced by a pointer to the most recent
copy of the same data. Because the most recent backup is a full version, you achieve the fastest
possible restores.
4. Users can enable an optional, secondary integrity check of data – a byte-for-byte comparison
between the deduplicated version with pointers and its original version. With this option, the
original backup is only replaced upon successful completion of the comparison.
5. Space reclamation occurs when duplicate data from previous backups is removed from the disk.
This can take some time, but results in previously consumed capacity being returned to a free
pool on the device.
Getting Deduplication Running on the VLS
This section explains how to get deduplication running on your VLS system including some
considerations for setting up the system, installing the firmware, and installing the deduplication
licenses.
Considerations
To make the most of the deduplication benefits, review these considerations before setting it up on
your VLS system:
• Virtual cartridge sizing — The system cannot deduplicate versions of a backup that are on the
same cartridge; the versions are not deduplicated until a new version is written to a different virtual
cartridge. Therefore, you want the cartridges to be sized big enough to contain an entire backup
job and to prevent too many backup jobs from piling up on the same cartridge, but small enough
that you are not wasting overall cartridge space.
• Additional nodes — For systems with long backup windows, you may want to include additional
nodes to speed up the post-processing deduplication.
• Additional capacity — Because you must store two full backups before the delta-differencing begins,
you may want to include additional disk capacity at least the size of the sum of the backups.
Installing the Firmware
The deduplication feature requires an upgrade to the VLS firmware version 3.0 or higher. Download
the VLS Firmware and Quick Restore CD Image appropriate for your VLS system from the HP website,
and burn it to a DVD (or CD). Then follow the instructions for using the Quick Restore DVD.
1. Save your configuration settings. See “Saving Configuration Settings” on page 146.
2. Download the VLS Firmware and Quick Restore CD Image appropriate for your VLS system from
the HP website.
3. Burn the image to CD to create your own Quick Restore DVD.
4. Follow the “Recovering from Operating System Failure” on page 209 procedure for re-installing
the operating system, including the instructions specific to restoring primary nodes.
NOTE:
You must install the Quick Restore DVD on each node of the VLS.
Deduplication92
Page 93
Installing the Deduplication Licenses
The deduplication feature is a licensed option. The number of deduplication licenses must match or
exceed the number of capacity licenses (based on LTU) on the VLS device. See “Installing Additional
Licenses” on page 45 for installation instructions.
After installing the required deduplication licenses, the VLS automatically reboots. When the system
is back up, it first checks the standard capacity licenses and then the deduplication licenses. Once
the deduplication licenses are verified, the deduplication feature is automatically enabled for all
supported backup types.
No further setup is required. When the next backup begins, the deduplication process begins mapping
the content of that backup. After the second backup, the system delta-differences (compares) the two
backups and the deduplication proceeds.
You may choose to disable some backup types; see “Configuring Deduplication Options” on page
93 for details.
Configuring Deduplication Options
You can include or exclude specific backups or types of backup (e.g., server type) from the
deduplication process and choose the deduplication algorithm used.
NOTE:
These options are not available until you have installed the appropriate number of deduplication
licenses.
1. Select the System tab.
2. Expand Chassis on the navigation tree.
3. Expand Deduplication on the navigation tree.
4. Select Configuration from the navigation tree.
The Configuration screen displays. See Figure 14.
Figure 14 Configuring deduplication options
.
5. Select the data types to change.
HP StorageWorks 12000 Gateway Virtual Library System User Guide 93
Page 94
6. Select the new policy state or deduplication algorithm from the appropriate list.
By default, deduplication is enabled for all data types that support it.
By default, file servers will back up using a file-level differencing algorithm. Because in some
cases this algorithm may be less space efficient (e.g., if the file server is full of very small files),
there is a backup-level algorithm. Note that database data defaults to the backup-level differencing
algorithm.
7. Select GO next to the pull-down field you changed.
The screen refreshes and updates the information.
8. Select Enable/Disable Enhanced Data Integrity Check in the task bar to toggle this option.
The integrity check runs a second pass verification over the data after deduplication to ensure
that the deduplicated tape matches the original version it will replace. This is disabled by default
because of its significant impact on performance.
NOTE:
You can set the state and backup algorithm at the individual backup job level. On the Configuration
screen, select a specific data type to display all the backup jobs of that type, then follow steps 6 and
7 above.
Editing the Data Protector Configuration
Data Protector adds one suffix to the backup job names of full backups and a different suffix to the
backup job names of incremental backups. Because the job names are not identical, full backups will
not deduplicate against incremental backups. However, you can set up deduplication to strip off the
suffixes so the two types of jobs will deduplicate.
From Command View VLS:
1. Select the System tab.
2. In the navigation tree, select Chassis. The chassis details screen opens
3. Under the Maintenance Tasks list, select System Maintenance.
4. From the task bar, select Edit Data Protector Configuration.
5. Enter the suffix of the full backup job names in the text box.
6. Select Submit. The suffix appears in a list beneath the text box.
7. Enter the suffix of the incremental backup job names in the text box.
8. Select Submit. The suffix is added to the list on the screen.
9. Repeat this procedure for all of the suffixes you want deduplication to ignore.
10. When you have added all of the necessary suffixes, select Return.
Viewing Deduplication Statistics and Reports
In Command View VLS, you can view statistics on the deduplication process by summary, backup
report, cartridge report, or system capacity.
Deduplication94
Page 95
Deduplication Summary
The Deduplication Summary displays a graph depicting the storage savings achieved with data that
has been fully deduplicated.
1. Select the System tab.
2. Select Chassis on the navigation tree to expand it.
3. Select Deduplication.
The deduplication summary displays.
In the graph displayed, the original data is the uncompressed physical size of all user data that
has fully deduplicated; the deduplicated data is the actual physical storage space consumed by
the original data after it has been both compressed (if enabled) and fully deduplicated.
Deduplication Backup Report
The backup report provides information on the deduplication of your backup jobs.
1. Select Backup Report from the navigation tree or from the task bar of the Deduplication Summary
screen.
The backup report options display.
2. Unselect any agents, backup types, or states you want to exclude from the report. By default, all
supported and enabled backup jobs are selected and display in the report.
3. Select View Backups.
The screen displays a list of backup jobs meeting the set criteria and includes the following
information:
• State — the state of the backup job (see below)
• Backup Name
• Policy
• Type
• Logical Size — the size of the backup data sent to the VLS (before deduplication and com-
pression)
• Physical Size Estimate — the disk space currently used to store the compressed backup, which
varies over time as deduplication processes the backup and reclaims redundant disk space
• Dedupe Ratio Estimate — the estimated deduplication ratio (based on the Logical Size divided
by Physical Size Estimate)
4. From the results list, select a backup name to see the backup statistics for that particular job.
The backup information includes a graph depicting the original data size (shown as zero prior
to the deduplication), the deduplicated size, and the unprocessed data. In the Cartridge Details,
select a barcode to see its cartridge report.
The deduplication reports show the following states:
Waiting for Next Backup — the backup has nothing to difference against and is therefore waiting
for a new backup. Incr/diff backups difference against the new full backup, not the old full backup.
Delta-diff in Process — the backup has identified another version of itself to difference against
and is now running differencing to identify the duplicate data between the two versions. With
HP StorageWorks 12000 Gateway Virtual Library System User Guide 95
Page 96
multi-stream backups, this process may take multiple tries (going back to "Waiting for Next Backup"
state each time) until the differencing locates the correct stream.
Pending Reclamation — the differencing is complete (duplicate data has been identified) and
space reclamation is now waiting for full cartridges before it can begin.
Partially Reclaimed — in a backup job that spanned multiple cartridges, the full cartridges have
been space reclaimed but the last tape in the spanned set (which is partially full) is waiting until that
tape is full before it can reclaim space.
Dedupe Complete — deduplication, including all space reclamation, is complete for this backup
job.
No Match Found — indicates backups that cannot be deduplicated because they were unable
to match with their previous version due to large-scale modification.
In the detailed Backup and Cartridge reports, the Dedupe Ratio Estimate represents the overall
compression ratio (including both deduplication and compression) of that backup/cartridge based
on the amount of logical backup data stored versus the amount of physical disk space used. If the
backup job status is “Waiting for next backup,” “Delta-diff in Progress,” or “Pending Reclamation,”
the ratio will only include the compression because deduplication will not have actually space reclaimed
that tape and therefore will not have saved any disk space. If the status is “Partially Reclaimed” or
“Dedupe Complete,” the backup disk space has been partially or full reduced by deduplication and
the ratio represents compression plus deduplication. The Dedupe Estimate in GB follows the same
logic. The “Saved” value represents the amount of disk space reclaimed by deduplication (Logical
minus Physical values).
Deduplication Cartridge Report
The cartridge report provides information on the deduplication of your backup jobs at the cartridge
level.
1. Select Cartridge Report from the navigation tree or from the task bar of the Deduplication Summary
screen.
The cartridge report options display.
2. Select View corresponding to the report you want to view. You can view all cartridges, or view
a specific barcode prefix or virtual library.
The screen displays the list of cartridges meeting the set criteria.
3. From the results list, select a cartridge to see all of the backup jobs on that cartridge.
The report includes the following information:
• Library
• Barcode
• Logical Size — the size of the backup data sent to the VLS (before deduplication and com-
pression)
• Physical Size — the disk space currently used to store the compressed backup, which varies
over time as deduplication processes the backup and reclaims redundant disk space
• Dedupe Ratio Estimate — the estimated deduplication ratio (based on the Logical Size divided
by Physical Size)
Deduplication96
Page 97
NOTE:
If a cartridge is full and all jobs on it have been delta-differenced except for one job that is waiting
for another backup, you can have the cartridge reclaimed by temporarily disabling the one remaining
backup job. Disabling the backup type disables all instances of that backup type on all cartridges
that have not yet been delta-differenced. When you re-enable the backup type, it allows deduplication
for future instances of that backup type.
Deduplication System Capacity
You can view specific details about the system capacity using deduplication.
Select System Capacity from the navigation tree or from the task bar of the Deduplication Summary
screen.
The screen displays the following information:
• Total physical capacity — the capacity of the entire VLS system
• Reserved for system — the amount of capacity needed to perform system functions (for example,
storing the meta-data)
• Usable capacity — the total capacity that can be used for deduplication (Total Physical Capacity
minus Reserved for System)
• Used capacity — the capacity currently in use
• Available capacity — the capacity currently available (Usable Capacity minus Used Capacity)
• Logical Data — the amount of backup data sent to the VLS (before deduplication and compression)
• Used Capacity — the capacity currently in use
• System Ratio — the ratio of the Logical Data divided by the Used Capacity
• Space Savings — the percentage of capacity saved by deduplication
