WARRANTY STATEMENT: To obtain a copy of the warranty for this product, see the warranty information website:
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 9000–series virtual library system models.
VLS9000-series Components
A typical VLS9000-series system consists of at least one VLS9000 node, at least one VLS9000 array
(one base disk array enclosure and three expansion disk array enclosures), and one VLS9000
connectivity kit (two Ethernet switches for internal inter-node connections and two Fibre Channel
switches for disk storage connections). See the drawing of a racked system below. The VLS9000 7.5
TB and 10 TB systems consist of one node, one Ethernet switch, one base disk array enclosure, and
up to three expansion disk array enclosures.
Each VLS9000 node contains hardware data compression, dual processors, one 4 Gb quad port
Fibre Channel HBA, eight 2048 MB memory modules (for a total of 16 GB), and two 120 GB SATA
hard drives.

You can install either the VLS9000 20-port or 32-port connectivity kit with the VLS9000-series. (The
VLS9000 7.5 TB and 10 TB systems omit the connectivity kit.) The 20-port connectivity kit includes
two 10-port Fibre Channel switches and two Ethernet switches. The 32-port connectivity kit includes
Introduction18
Page 19
two 16-port Fibre Channel switches and two Ethernet switches. The number of Fibre Channel ports
available determines the number of arrays and nodes that can be installed. The 32-port connectivity
kit allows you to install more VLS9000 nodes and VLS9000 arrays in your VLS9000-series system
than the 20-port connectivity kit.
VLS9000–series scalability considerations:
• Two Fibre Channel ports (one Fibre Channel port on each Fibre Channel switch) are required for
each VLS9000 node
• Two Fibre Channel ports (one Fibre Channel port on each Fibre Channel switch) are required for
each VLS9000 array
• Up to two VLS9000 arrays may be installed for every VLS9000 node in a VLS9000-series system
• Adding nodes and arrays increases the VLS9000-series storage capacity
• Adding nodes to a system that has more than one array installed for every node increases perform-
ance
If you have a 20–port connectivity kit, you can install a total of ten devices, consisting of a combination
of arrays and nodes. If you have a 32–port connectivity kit, you can install a total of 16 devices.
By interconnecting two 32–port connectivity kits with an interswitch link kit, you can further expand
the scalability of VLS9000–series. See Table 1 and Table 2 for configuration options.
NOTE:
For maximum performance, install one VLS9000 array for every VLS9000 node installed.
For maximum capacity, install two VLS9000 arrays for every VLS9000 node installed.
To add a VLS9000 array, purchase a VLS9000 capacity kit. A VLS9000 capacity kit includes one
VLS9000 array and one capacity license for the VLS9000 array. If you have a 7.5 TB or 10 TB
system, you can add expansion disk array enclosures individually.
See the HP StorageWorks VLS9000 Virtual Library System Quickspec on the HP web site (http://
This section details the steps to install the VLS hardware from installation preparation to final cabling.
Preparing for the Installation
Tools for Installation
• Two people
• #1 and #2 Phillips screwdriver
• Standard screwdriver
• Allen wrench (provided; used with 6-mm screws and #12-24 x 3/8-inch sockethead screws)
• #3 Pozidrive screwdriver
• 7/16 inch wrench
• 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.
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.
HP StorageWorks21
Page 22
• 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

but have not been tested with the VLS.
Rack Warnings
WARNING!
To reduce the risk of personal injury or damage to the equipment, be sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if more than one com-
ponent is extended for any reason.
WARNING!
To reduce the risk of personal injury or equipment damage when unloading a rack:
• At least two people are needed to safely unload a rack from a pallet. An empty 42U rack can
weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and may become unstable
when being moved on its casters.
• Never stand in front of a rack when it is rolling down the ramp from the pallet. Always handle a

The VLS9000-series is a scalable storage solution. For more information on VLS9000-series
configuration options, see VLS9000-series Components.
Whether you are installing one rack or multiple racks of VLS9000-series equipment, the rack mounting
order is essentially the same. See Figure 7 and Installing the VLS Node into a Rack.
Use the following information to understand rack mounting VLS9000-series equipment:
• Depending on the configuration, a VLS9000–series device requires between one and four racks.
If available, install racks two through four next to the first rack. See Figure 8.
Hardware Installation30
Page 31
Figure 8 VLS9000–series four-rack configuration, Racks 1–4 (left to right)
.
• If the racks you are using did not come with PDUs installed, see Installing PDUs before racking
VLS9000–series equipment.
• Install a maximum of four arrays in each rack, starting above the PDUs at rack positions 3 and 4.
See Installing the Disk Array Enclosures into a Rack.
• Install an Ethernet switch or 32– or 20–port connectivity kit above the arrays in the first rack. See
the instructions beginning in Installing Fibre Channel Switches 4/10q onto Racking Shelf.
If available, install a second 32–port connectivity kit above the arrays in rack three.
• Install a maximum of four nodes at the top of the rack, above the arrays, and the connectivity kit,
if present. See Installing the VLS Node into a Rack.
• Unless directed to do so, do not leave spaces between devices.
After racking all VLS9000-series equipment, see Installing VLS9000 Cables. If the configuration you
are installing consists of one Ethernet switch or connectivity kit, cabling the system completes the
installation.
If the configuration you are installing consists of two 32-port connectivity kits, you must additionally
connect the connectivity kit in rack one to the connectivity kit in rack three. See Installing VLS9000-series
Interswitch Link Kit. The two cabled connectivity kits function as one logical set of switches.
Installing the VLS9000 7.5 TB and 10 TB Systems
To install the 7.5 TB and 10 TB systems, use the following sections. The installation is the same as for
other VLS9000 systems except where noted. Not all of the information will apply.
When installing disk array enclosures for the 7.5 TB and 10 TB systems, keep in mind that you install
the base disk array enclosure first and install expansion disk array enclosures as you purchase them
working down the rack. This differs from other VLS9000 systems where you install the expansion disk
array enclosures at the bottom of the rack and work up to the base disk array enclosure.
HP StorageWorks31
Page 32
The expansion disk array enclosures come with capacity options of either 7.5 TB or 10 TB. Install the
same capacity expansion disk array enclosures as you purchased for the base disk array enclosure;
mixing 7.5 TB capacity with 10 TB capacity is not recommended.
Installing PDUs
If the rack you are using already has PDUs (power distribution units) installed, skip this procedure.
Hardware Installation32
Page 33
1.Determine the number of PDUs to install.
• The number of PDUs you install is based on the number of arrays to install.
• Install up to four arrays in one rack.
• Install up to a maximum of four additional arrays in racks two through four.
Use the following table to determine how many PDUs to install:
PDMsPDUsArrays
NOTE:
PDUs are installed in pairs.

Installing the Disk Array Enclosures into a Rack
This section describes how to install the disk array enclosures into a rack.
Rack Mounting Requirements
Each disk array enclosure requires a vertical rack space of 2U (equivalent to 89 mm, or 3.5 inches).
Install three expansion disk array enclosures for the first array (array 0) in the rack positions 3 and
4. Starting at the bottom distributes the weight correctly in the cabinet. See Figure 14. Rack positions
1 and 2 are reserved for PDUs. See Installing PDUs. Next, install a base disk array enclosure in the
slots just above the expansion disk array enclosures. Repeat for the next array. Install up to four arrays
in a rack. Install the fifth through eighth arrays (if available) at the bottom of a second rack. Install
the ninth through twelfth arrays (if available) in a third rack. Install the thirteenth through sixteenth
arrays (if available) in a fourth rack.
If you have the base VLS9000 7.5 TB or 10 TB system and you anticipate adding more disk array
enclosures in the future, consider leaving up to three 2U spaces open at the bottom of the rack. This
eliminates having to reinstall existing components as you expand.

This section explains how to configure the identities of each node after the VLS9000–series is physically
installed.
Configuring Primary Node 0
To configure the primary node:
1.Power on array 0. All other arrays should be powered off.
2.On the primary node, connect to the serial port or use the keyboard and mouse ports to connect
to a console.
3.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.
4.Enter m. The node will then run cable checks and configuration checks.
5.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.
6.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.
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.

8.Select Nodes from the navigation tree.
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 tree. 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. Power on array 1 (or next array in series).
NOTE:
The VLS sequentially numbers arrays as they are added starting with Array 0 . Only power
up and install one array at a time, so you can control the number assigned to each array.
Only power up one array for each node configured to prevent a capacity license violation.
13. Add the array 1 (or next array in series) storage to the VLS:
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 143.
b.In the Storage tab navigation tree, select Storage LUNs.
c.Select Discover Unconfigured Storage from the task bar.
14. Repeat these steps to add nodes until all of the nodes are listed in the navigation tree.
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.

4 Storage Configuration
This section describes how to configure the storage pool policy and add or remove storage as needed
after the nodes have been configured.
Managing VLS9000–series Capacity
There are several ways to manage the capacity of your system:
• Increase the number of VLS9000 nodes
• Increase the number of VLS9000 arrays by adding capacity kits. See Adding a VLS9000 Capacity
Kit.
• Reduce the number of VLS9000 arrays by removing capacity kits. See Removing a VLS9000
Capacity Kit.
• Create storage pools. See Configuring the Storage Pool Policy.
Adding a VLS9000 Capacity Kit
Add capacity by increasing the number of VLS9000 arrays in your VLS9000-series system. Up to two
arrays may be added per node installed in a VLS9000-series system. To add an array, purchase and
install a VLS9000 capacity kit. A VLS9000 capacity kit includes one VLS9000 array with an upgrade
capacity license for the additional array.
If you have a VLS9000 7.5 TB or 10 TB system, you can purchase expansion disk array enclosures
up to a total of four enclosures (equal to one array) for your system. If you purchase a VLS9000
capacity kit to increase your capacity, you must also purchase a 20– or 32–port connectivity kit and
additional nodes.
NOTE:
The VLS sequentially numbers arrays as they are added, starting with Array 0. Only add one VLS
array at a time so you can control the number assigned to each array.
To add a VLS9000 capacity kit:
HP StorageWorks75
Page 76
1.Install the capacity license if needed. See Installing Additional Licenses.
Each VLS9000 node comes pre-installed with a base capacity license for one VLS9000 array
(one base disk array enclosure and three expansion disk enclosures). Upgrade capacity licenses
(one per array) must be installed if more than one array is installed per node in a VLS9000-series
system.
CAUTION:
If an array is added to a VLS before the upgrade capacity license for the additional array
is installed, a capacity license violation will occur.
If the capacity license violation is detected during boot, this will disable the VLS storage
capacity, so that the VLS is unable to perform for read/write operations. VLS storage capacity
is re-enabled once the capacity license is installed on the VLS (without needing to reboot).
If the capacity license violation is detected when Discover Unconfigured Storage is selected,
this will prevent the new array from being added to the VLS. However, the VLS will remain
operational. When the capacity license is installed, the new array is automatically added
to the VLS (without needing to reboot).
2.Install the array into the rack. See “Installing the Disk Array Enclosures into a Rack” on page 50.
3.Cable the array to the VLS. See “Installing VLS9000 Cables” on page 58.
4.Power on the array. See “Powering on VLS9000 Arrays” on page 133.
5.Add the new disk array storage to the VLS.
If your system is running firmware version 3.x, reboot the entire VLS.
If your system is running firmware version 1.x or 2.x, you can reboot the VLS 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 143.
b.In the Storage tab navigation tree, select Storage LUNs.
c.Select Discover Unconfigured Storage from the task bar.
Removing a VLS9000 Capacity Kit
Remove capacity by decreasing the number of VLS9000 arrays installed in your VLS9000-series
system. At least one array must be installed for every node installed in a VLS9000-series system (except
in the 7.5 TB and 10 TB systems which can have a single disk array enclosure).
Removing arrays from the system destroys all current virtual tapes in the system. Once arrays are
added to the VLS, the only way they can be removed from the a VLS storage pool is by powering off
the nodes, removing the arrays, powering on the nodes, then running Rebuild All Storage Pools (see
Rebuilding all Storage Pools). This will delete the arrays from the configuration and reformat the
remaining arrays into working capacity.
In addition, if you add a used VLS9000 capacity kit to another system you must perform the steps
listed in this section and then run Rebuild All Storage Pools in order to add the capacity to your system.
This destroys all current virtual tapes in the system while it reformats all the arrays to reflect the new
working capacity.
Storage Configuration76
Page 77
Configuring the Storage Pool Policy
VLS automatically creates storage pools on the VLS9000 arrays in the system based on your storage
pool policy. Storage pools are defined in terms of whole arrays (one base disk array and three
expansion disk arrays). Use the Storage Pool Policy Wizard to set the storage pool width across the
arrays in the system:
• All (default)—One storage pool across all arrays
• 1—One storage pool across each array
• 2—One storage pool across every two arrays
• 4—One storage pool across every four arrays
Partially-populated storage pools may result if storage pool policy 2 or 4 is selected. For example, if
the storage pool policy is 2 and there are three arrays in the system, the VLS divides the three arrays
into two storage pools. One storage pool spans across two arrays, and the other storage pool spans
across one array. If a fourth array is added, the VLS automatically adds it to the storage pool with
only one array.
To set the storage pool policy:
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 143.
2.Select Storage Pools in the navigation tree.
3.From the task bar, select Edit Policy. The Storage Pool Policy Wizard screen is displayed.
4.Select the number of arrays wide in the Number of Arrays Wide field and then click Next.
Only the Number of Arrays Wide default value can be changed.
5.Click Next to confirm.
If the existing storage pools do not fit into the new storage pool policy selected, a dialog box
will ask if you want to erase the existing storage pools to create the new policy. Select Yes to
rebuilt all storage pools or No to cancel the change. See Rebuilding all Storage Pools.
6.Click Finish.
Viewing the Storage Pool
To view the storage pool information:
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 143.
2.Select Storage Pools in the navigation tree.
3.Select the storage pool to view in the navigation tree.
The storage pool details window opens.
Rebuilding all Storage Pools
To delete all information on the VLS9000 arrays and reformat them, perform a Rebuild All Storage
Pools from Command View VLS.
HP StorageWorks77
Page 78
CAUTION:
Rebuild All Storage Pools destroys all current virtual tape cartridges in the system.
To rebuild 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 143.
2.Select Storage Pools in the navigation tree.
3.Select Rebuild All Storage Pools from the task bar.
4.Select Rebuild, or, if your system has deduplication enabled, select Restart Emulations in
Maintenance Mode from the task bar.
Systems with deduplication enabled must enter Maintenance Mode before rebuilding the storage
pools. Maintenance Mode reboots the system with deduplication disabled and the front fibre
ports down.
5.If your system has deduplication enabled, wait until the system has completed rebooting into
Maintenance Mode, then follow steps 1 through 3. The system will reboot again; when the system
is back up, deduplication is enabled and the front fibre ports are back up.
Rebuilding a Storage Pool
To delete all information on the VLS9000 arrays for one specific storage pool and reformat them,
perform a Rebuild Storage Pool from Command View VLS.
CAUTION:
Selecting Rebuild Storage Pool destroys all current virtual tape cartridges in that storage pool.
To rebuild a storage pool:
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 143.
2.Select Storage Pools in the navigation tree.
3.Select the specific storage pool you want to rebuild.
4.Select Rebuild Storage Pool from the task bar.
5.Click Rebuild.
CAUTION:
Do not resume backup operations until the rebuilt arrays have finished initializing (can take up to 24
hours). View the “Disk Array x” details page on the Systems tab of Command View VLS to view the
array state. The disk array is still initializing when the array state is “Initializing.”

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.
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.
The base license on the node enables the storage that is part of the base SKU. The capacity bundle
includes the capacity license and the registration materials necessary for installing capacity licenses.
NOTE:
Do not discard the registration materials included in the capacity bundle.
• 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.In Command View VLS, select the System tab.
10. Select Chassis on the navigation pane.
HP StorageWorks79
Page 80
11. Select Licensing from the task bar.
The Manage Upgrade Licenses screen displays all of the existing licenses.
12. Select Add License.
13. In the empty field that displays, paste the license key.
14. Select OK.
The screen returns to the Manage Upgrade Licenses list and includes the newly installed licenses.
NOTE:
When installing deduplication licenses, the VLS system will automatically reboot. This may take a few
minutes to begin; when it does, you will see a message on the Notifications tab.

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 83.
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 89 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/Replication82
Page 83
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 StorageWorks83
Page 84
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/Replication84
Page 85
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 113 and
“Importing Data from Physical Tapes for Tape Initialization” on page 114 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 a VLS9000
To connect the destination library to the VLS9000:
1.Connect your destination library to the VLS by connecting the library to the Fibre Channel switches
in the VLS9000 connectivity kit.
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 StorageWorks85
Page 86
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 87.
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 87 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/Replication86
Page 87
1.Select the Automigration/Replication tab.
2.Expand Destination Libraries in the navigation pane.
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 87 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 pane, 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 pane.
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 StorageWorks87
Page 88
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 pane 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/Replication88

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 pane 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 pane.
4.From the task bar, select Create Echo Copy Pool.
The CREATE ECHO COPY POOL screen displays (see Figure 28).
Figure 28 Creating an echo copy pool (LAN/WAN shown)
.
5.Enter a start slot number and an end slot number for the copy pool from within the available slot
range.
6.Select the local library where your echoed virtual cartridges will be placed from the Local Library
list.

Page 90
7.Select the storage pool where your echoed virtual cartridges will be stored from the Storage Pool
list.
8.For LAN/WAN echo copy pools, select whether your replication is for deduplicated or
non-deduplicated backups.
9.For LAN/WAN echo copy pools, select “Initialize via Tape Transport” only if you intend to use
this echo copy pool for the one-time process of tape initialization. (See
“Tape Initialization” on page 84.)
10. Select Next to set the policies.
Automigration/Replication90
Page 91
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:
Figure 29 Setting the echo copy pool policies (LAN/WAN shown)
.
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.
• Echo Copy on MailSlot 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
HP StorageWorks91
Page 92
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
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.
Automigration/Replication92
Page 93
13. Beneath the policy settings you just entered, enter the details of the window duration:
Figure 30 Setting up the availability windows (LAN/WAN shown)
.
• 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.
HP StorageWorks93

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 will need to use one of the
following three 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 use Command View VLS to 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.Under Destination Libraries in the navigation pane, expand the library you want to restore.
3.From the navigation pane, select MailSlot.
4.From the task bar, select Load Media for Restore.
5.From the LOAD MEDIA FOR RESTORE screen in the main window, select the source slot of the
media to be restored.
6.Select Next.
7.Select a destination slot from the list provided.
8.Select Next to display the specifics of the restore to be performed.
Automigration/Replication94
Page 95
9.Select Submit.
The mailslot screen displays, along with the message, “The media, [media name], was successfully
loaded.” Also, the media that has been restored is no longer in the mailslot.
10. From the System tab, under Virtual Libraries, verify that the tape is created.
NOTE:
Using Load Media for Restore will create a virtual tape that is exactly equal in size to the physical
tape, despite the established sizing factor.
Restoring from a LAN/WAN Virtual Cartridge
1.Select the Automigration/Replication tab.
2.Under Destination Libraries in the navigation pane, expand the library you want to restore.
3.From the navigation pane, select Slots.
4.On the task bar, select Restore Media.
5.Select the slot number or Copy Pool you wish to restore.
NOTE:
You can only restore one slot at a time.
6.Select Submit.
The Restore Media screen refreshes with a message that indicates the restore was successful.
Loading Blank Media into an Echo Copy Pool
To move a blank tape (or a tape that should be considered blank) from a mailslot on a destination
library into an echo copy pool, use Load Blank Media:
CAUTION:
Any tape moved into an echo copy pool in this way will be considered blank, even if it contains data.
1.From Command View VLS, select the Automigration/Replication tab.
2.In the navigation pane under the appropriate destination library, select MailSlot to display the
list of mailslots on that library.
3.From the task bar, select Load Blank Media.
4.From the LOAD BLANK MEDIA screen, select the source slot.
5.Select Next.
6.Select the destination slot.
7.Select Next to display the specifics of the media to be loaded as a blank tape.
HP StorageWorks95
Page 96
8.Select Submit.
The mailslot screen refreshes, along with the message, “The media, [media name], was successfully
loaded.” Also, the media that has been loaded is no longer in the mailslot.
Automigration will then automatically create a matching blank virtual cartridge in the source
virtual library defined for this echo copy pool.
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:
1.From Command View VLS, select the Automigration/Replication tab.
2.From the navigation pane under the appropriate destination library, select MailSlot to display
the list of mailslots on that library.
3.From the task bar, select Load Media for Overwrite.
4.From the LOAD MEDIA FOR OVERWRITE screen, select the source slot.
5.Select Next.
6.Select the destination slot.
7.Select Next to display the specifics of the media to be loaded for overwrite.
8.Select Submit.
The mailslot screen refreshes, along with the message, “The media, [media name], was successfully
loaded.” Also, the media that has been loaded is no longer in the mailslot.
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 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.
Automigration/Replication96
Page 97
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 pane.
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
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 pane. 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 94.
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 197 for SMI-S information.
HP StorageWorks97

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 pane 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.
3.From the task bar, select Create Smart Copy Pool.
The CREATE NEW SMART COPY POOL screen displays (see Figure 31).
Figure 31 Creating a new smart copy pool (with sample slot range error message)
.
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.
Automigration/Replication98
Page 99
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 pane.
2.Under Destination Libraries, select Copy Pools.
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 pane 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.
4.Select Next.
5.Select the destination slot.
6.Select Next to display the specifics of the media to be loaded as a blank tape.
7.Select Submit.
The mailslot screen refreshes, along with the message, “The media, [media name], was successfully
loaded.” Also, the media that has been loaded is no longer in the mailslot.
Loading Media into a Smart Copy Pool for Overwrite
To load a scratch or expired tape (a tape that was previously backed up to and is being reused) from
a mailslot on a destination library into a smart copy pool, use Load media for overwrite:
HP StorageWorks99

Editing Copy Pools
The following sections describe the copy pool edit operations available to the user.
Moving a Copy Pool
When there is not enough space left on a virtual library, a copy pool can be moved to a different
virtual library. To move a copy pool from one virtual library to another:
1.Select the Automigration/Replication tab and expand the task bar of the navigation pane.
2.Under Destination Libraries, select Copy Pools.
3.From the Name column in the copy pools lists, select the copy pool to be moved.
4.From the Copy Pool Details window task bar, select Change Local Library.
5.From the CHANGE LOCAL LIBRARY window, verify the current local library on which the pool
resides.
6.Select the new local library, then select Submit.
The Echo Copy Pool Details window displays, along with the message, “The local library was
successfully changed.”
NOTE:
When an echo copy pool moves to a different local library, the associated automigration tapes
automatically move with it.
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:
