1Introduction
This section describes the HP StorageWorks 300 virtual library system features and models.
Features
The HP StorageWorks 300 virtual library system (VLS) is a RAID disk-based SAN backup device that
emulates physical tape libraries, allowing you to perform disk-to-virtual tape (disk-to-disk) backups using
your existing backup application(s). The many benefits of performing data backups to a VLS instead of
physical tape are described in Benefits.
The VLS emula
libraries. Y
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 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

system requirements and restrictions.
Benefits
Data stor
using a backup application.
Integrating a VLS into your existing storage and backup infrastructure delivers the following benefits:
• Faster backups
• Faster single file restores
• Lower operating costs
• More efficient use of storage space
• Reduced risk of data loss and aborted backups
ed on a VLS is easily cloned to physical tape for off-site disaster protection or long-term archival
BackupspeedsarelimitedbythenumberoftapedrivesavailabletotheSANhosts. TheVLS
emulates many more tape drives than are available in physical tape libraries, allowing more hosts
to run backups concurrently.
The VLS is optimized for backups and delivers faster performance than a simple disk-to-disk solution.
Asinglefile can be restored much faster from disk than tape.
Fewer physical tape drives and cartridges are required as full backups to tape are eliminated. Also,
fewer cartridges are required as small backups stored on multiple virtual cartridges can be copied to
one physical cartridge.
Physical tape libraries cannot share storage space with other physical tape libraries, and physical
cartridges cannot share storage space with other physical cartridges. This unused storage space
is wasted.
Storage space is not wasted in a VLS, because VLS storage space is dynamically assigned as it is
used. Storage space is shared by all the libraries and cartridges configured on a VLS.

Aborted backups caused by tape drive mechanical failures are eliminated.

Sy stem status monitoring
VLS hardware, e
monitored by th
Anotification alert is generated by the VLS software when a ha rdware or environmental failure is detected
or predicted. VLS notification alerts are displayed on Command View VLS, and can also be sent as mail
to the mail addresses you specify and/or SNMP traps to the m anagement consoles you specify.
For more information about viewing VLS hardware status, and/or receiving VLS notification alerts by
mail or as SNMP
Redundancy
The VLS includes some important redundancy features:
• Redundant fans
Each node includes redundant fans. If a fan fails in a node (head unit), the remaining fans run at
a faster speed, temporarily providing enough cooling.
• Redundant power supply
Each node includes a redundant power supply. With redundant power supplies, if one power
supply fails in a node, the remaining functional power supply provides enough power for the
node to function. HP recommends that the primary power supplies be connected to a separate
powersourceatthesitefromtheredundantpowersupplies.
CAUTION:
Replace a failed fan or power supply as soon as possible to maximize the life expectancy of the
remaining fan(s) or power supply and to maintain redundancy.

traps, see Monitoring.
• Redundant system disks
Each VLS node (head unit) contains two system hard drives configured into a RAID 1 (mirrored)
volume. This provides dual boot capability and quick recovery if one of the system hard drives fail.
For more information about VLS features, visit the H P web site: h
Components
A VLS300 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. Each node contains dual processors, two dual port FC HBAs, four 512 MB memory modules,
and two 80 Gb hard drives.
No external storage is included with the VLS300; instead, the gateway uses external storage in existing
arrays.

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 VLS300 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 bundles, each of which adds licensing
for one additional external array LUN and increases maximum external capacity by up to 2 TB.
NOTE:
Maximum capacity for each LUN on the VLS300 is 2 TB.
Adding nodes and licenses increases the VLS300 storage capacity as shown in Table 2. Adding nodes
also increases the performance. See the HP StorageWorks VLS300 Virtual Library System Quickspec on
the HP web site (h
ttp://h18006.www1.hp.com/products/storageworks/6000vls) for performance data.

This section details the steps to install the VLS hardware:
• Preparing for the installation
• Unpacking
• Id entifying the VLS shipping carton contents
• Installing the VLS node(s) into a rack
• Install the 100 Mb Ethernet switch 25 24 into a rack
• Install the 1 Gb Ethernet switch 2824 into a rack
• Installing VLS300 cables
Preparing for the installation
PreparetheEVAfortheVLS300
Arrays that will be connected to the VLS300 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 FC switches/fabrics or two zones on an external FC switch/fabric so that
there are two (high availability) data pathways from the VLS300 to the EVA.
• All of the required VRaid LUNs required for the VLS have been created on the EVA according to the
design g uidelines (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).
If this has not been done, refer to the solutions guide for instructions.
Tools for installation
• Two p eople
• Phillips screwdriver
• Box cutt

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.

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.
Rack warnings
WARN ING!
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
component is extended for any reason.
WARN ING!
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
rack from both sides.
Optimum environment
When installing a VLS in a rack, select a location that meets the environmental standards described
in this section and Environmental specifications.
Space and airflow requirements
To allow for servicing and adequate airflow, observe the following space and airflow requirements
when deciding where to install a rack:
• Leave a
• Leave a minimum clearance of 76.2 cm (30 in) behind the rack.
• Leave a minimum clearance of 122 cm (48 in) from the back of the rack to the back of another

minimum clearance of 122 cm (48 in) in front of the rack.
hen racks are back-to-back.
HP StorageWorks
21
Page 22
CAUTION:
To prevent improper cooling and damage to the equipment, do not block the ventilation openings.
When vertical space in the rack is not filled by a VLS or rack component, the gaps between the
components cause changes in airflow through the rack and across the servers. Cover all gaps with
blanking panels to maintain proper airflow. Using a rack without blanking panels results in improper
cooling that can lead to thermal damage.
The Compaq 10000 Series racks provide proper VLS cooling from flow-through perforations in the front
and rear doors that provide 64 percent open area for ventilation.
CAUTION:
If a third-party rack is used, observe the following additional requirements to ensure adequate airflow
and to prevent damage to the equipment:
• Front and rea
5,350 sq cm (
(equivalent to the required 64 percent open area for ventilation).
• Side—The clearance between the installed rack component and the side panels of the rack must
be a minimum
r doors—If the 42U rack includes closing front and rear doors, you must allow
830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow
of 7 cm (2.75 in).
Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the system in a
well-ventilated, climate-controlled environment.
The maximum recommended ambient operating temperature (TMRA) for the VLS system is 35° C (95° F).
The temperature in the room where the rack is loca ted must not exceed 35° C (95° F).
CAUTION:
To reduce the risk of damage to the equipment when installing third-party options:
• Do not permit optional equipment to impede airflow around the VLS or to increase the internal rack
temperature beyond the maximum allowable limits.
• Do not exceed the TM RA.
Power requirements
Installation of a V LS must comply with local and regional electrical regulations governing the installation
of information technology equipment by licensed electricians. This equipment is designed to operate in
installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for
Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options,
see the product rating label or the user documentation supplied with that option.
WARNING!
To reduce the risk of personal injury, fire, or damage to the equipment, do not overload the AC supply
branch circuit that provides power to the rack. Consult the electrical authority having jurisdiction over
wiring and installation requirements of your facility.
22
Hardware installation
Page 23
CAUTION:
Protect the VLS from power fluctuations and temporary interruptions with a regulating uninterruptible
power supply (UPS). This device protects the hardware from damage caused by power surges and
voltage spikes and keeps the system in operation during a power failure.
When installing a VLS connected to more than one disk array, you may need to use additional power
distribution devices to safely provide power to all devices. Observe the following guidelines:
• Balance the device power load between available AC supply branch circuits.
• Do not allow the overall system AC current load to exceed 80 percent of the branch circuit
AC current rating.
• Do not use common power outlet strips for this equipment.
• Provide a separate electrical circuit for each device.
Electrical grounding requirements
The V LS must be grounded properly for proper operation and safety. In the United States, you must install
the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250, as well
as any local and regional building codes. In Canada, you must install the equipment in accordance
with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other countries,
you must install the equipment in accordance with any regional or national electrical wiring codes, such
as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you
must be sure that all power distribution devices used in the installation, such as branch wiring and
receptacles, are listed or certified grounding-type devices.
Because of the high ground-leakage currents associated with multiple VLS and servers connected to the
same power source, HP recommends the use of a power distribution unit (PDU) that is either permanently
wired to the building’s branch circuit or includes a non-detachable cord that is wired to an industrial-style
plug. NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for this
purpose. Using c ommon power outlet strips for a VLS is not recommended.
Identifying the shipping carton contents
Unpack the VLS shipping cartons and locate the materials and d ocumentation necessary for installing the
VLS. All the rack mounting ha rdware and documentation necessary for installing a VLS node into a rack
is included in the node shipping carton. All the rack mounting hardware and documentation necessary
for installing a VLS disk array into a rack is included in the disk array shipping carton.
VLS300 system shipping carton
NOTE:
In addition to the contents of the shipping carton(s) and an existing EVA, you will also need a #1 Phillips
screwdriver , a #2 Phillips screwdriver , 1 Ethernet cable to connect to the existing external network, and 4–8 FC
cables to connect from the nodes to the external FC fabri cs/switches. These are not included with the VLS300.

LUN, you must then reconfigure the LUN numbering for all LUNs on the VLS300 that
follow the unpresented LUN in sequential numbering.
Managing VLS300 capacity
There are several ways to manage the capacity of your system:
• Add external LUNs to the VLS300 configuration. See Discovering array LUNs.
• Delete external LUNs from the VLS300 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
Discovering array LUNs
1. Discover the LUNs, either by rebooting the entire VLS300 or:
a. Open a Command View VLS session and log in as the administrator. See Opening a Command
View VLS session from Command View TL.
b. In the Storage tab n avigation 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.
2. Verify that the LUNs are properly assigned and that there are two data paths for each LUN.
40
Storage configuration
Page 41
a. Open a Command View VLS session and log in as the administrator. See Opening a Command
View VLS session from Command View TL.

d. Ensure that all LUNs are listed under each node, and that each has a preferred and secondary
path.
NOTE:
IfaLUNisnotrecognizedbyeachnode,theLUNisunusable.PresenttheLUNtoany
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
To remove a LUN from the device:
1. Unpresent the LUN to the VLS (see instructions below) or delete the LUN from the external a rray.
2. Restart emulations or reboot the device (see Restarting the VLS device emulations or Rebooting
the system).
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 VLS300 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.

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 for detailed instructions.
CAUTION:
LUN numbering must be sequential with no gaps. Gaps in LUN numbering will prevent the VLS300
from recognizing any nodes with a ny LUNs after the gap. For example, if LUN numbering is 0, 1, 2,
4,5,theVLS300willnotrecognizeLUNs4and5.
Configuring storage pools
VLS auto creates the first storage pool, but you must create any additional pools. To do so:
NOTE:
The VLS300 can have either one storage pool for all LUNs, or one storage pool for each array. Refer to
thesolutionsguidefordetails.

Setting the network settings using the VLS discovery utility
The V LS discovery utility looks for all the devices on the same subnet as the Windows computer on which
it is running. It then lists the devices and indicates whether they are configured (have an IP address)
or unconfigured.
You can use the VLS discovery utility to set the network settings on an unconfigured VLS, and to view
the network settings of configured devices. The utility can also be used to remove LUNs from the user
interfaceafteroneormoreLUNsarenolongerconfigured or have been removed from the VLS.
NOTE:
The V LS discovery utility can only be used to change the network settings on a VLS with no IP address.
Once a VLS has an IP address, either through the DHCP or the VLS discovery utility, its network settings
cannot be changed using the VLS discovery utility. Use the CLI command set or Command View VLS to
change the network settings on a VLS that has an IP address. See Setting the network settings using
the CLI command set.
To set the network settings using the VLS discovery utility:
1. Insert the VLS Documentation CD into the CD drive on a Windows system that is on the same
subnet as the VLS.
The CD auto-launches.
2. Click VLS discovery utility.

Enabling and disabling oversubscription
Because the VLS dynamically allocates storage space as data is written to virtual media, the VLS allows
you to allocate more cartridge capacity than is physically installed. This oversubscription feature permits
configuring your system for anticipated storage growth.
By default, oversubscription is disabled.
To enable oversubscription:

To disable oversubscription, click the Enabled box to deselect it.
NOTE:
Oversubscription cannot be disabled while cartridge capacity is oversubscribed.
Managing virtual device LUNs
The V LS has a LUN masking, a LUN mapping, and a port mapping feature that a llows you to restrict host
access to the LUNs (virtual libraries and tape drives) configured on the VLS, manually assign LUN numbers
to the virtual devices by host, and assign e ach virtual device to a specificFChostport.Thesefeatures
allow you to allocate the virtual devices to individual hosts and distribute the virtual tape drives across the
FC host ports to achieve maximum bandwidth. See Managing high availability for more information.
By default, the VLS allows all hosts connected to the VLS through the SAN to access all virtual devices
configured on the VLS. Also, the VLS software manages the LUN mapping so that the virtual device LUN
assignments always meet operating system requirements and restrictions. See Default LUN numbering and
Operating system LUN requirements and restrictions. Optionally, you can restrict host access to individual
virtual devices using the LUN masking feature then, for each LUN masked host, to use the LUN mapping
feature to manually assign LUN numbers to any virtual devices you want the host to be able to access.
See LUN masking and LUN mapping for reasons you may want to use these features.
Port mapping is required and allows you to assign each virtual device to one of the FC host ports or a
pair of FC host ports (if your backup solution supports this).

l device port mapped to any of the FC host ports is assigned the LUN number LUN0. The
e drive has been ad ded to a library since the last restart and the default LUN number
mbering meets the operating system LUN requirements.
Operating system LUN requirements and restrictions
Most operating systems require that each VLS FC host port connected to the SAN has a virtual device
with the LUN number LUN0 and no gaps in the LUN numbering (LUN0, LUN1, LUN2, and so on) . If the
operating system does not see a LUN0 on a VLS FC host port when it is scanning for new hardware
on the SAN, it will stop looking for LUNs on that port and erroneously report that there are no LUNs
(virtual devices) on that port. If the operating system sees a LUN0, LUN1, and LUN2 but not a LUN3 on
the port, it will stop looking for LUNs on that port when the gap in the LUN numbering is encountered.
Even though there may be more LUNs (such as LUN4), the operating system will erroneously report that
there are only three LUNs on the port.
In addition, operating systems are configured to only look for a maximum number of LUNs per device and
no more. Once the maximum number of LUNs is detected, the operating system stops looking. In the case
of the VLS, the operating system considers each FC host port to be one device with its own set of LUNs.
So, if the maximum number of LUNs an operating system is configured to see is eight, the operating system
will only see LUN0, LUN1, ..., LUN7 and will not see LUN8, LUN9 , ..., and up on each FC host port.
To get around the maximum LUNs p er device restriction, you can either:
• Increase the maximum LUNs per device setting for the operating system. See Troubleshooting
for more information.
• Use the VLS’s LUN masking feature to restrict the number of virtual devices the host’s operating
system sees on the VLS FC host port(s). Then, use the VLS’s LUN mapping feature to assign LUNs
to the virtual devices the host can see, such that the LUN numbers on each FC host port include a
LUN0 and no gaps in the LUN numbering. See LUN masking and LUN mapping for instructions.
LUN masking
By default all hosts on the SAN can access all the virtual libraries on the VLS. You can restrict a host’s
access to the virtual libraries and/or tape drives (virtual devices) on the VLS by performing LUN masking.
LUN masking should also be used when there are more virtual devices (LUNs) port mapped to a FC
host port than the operating system LUN restrictions support. This prevents the host’s operating system
from seeing the virtual devices it needs to see on the port. For example, if a host’s operating system is
configured to only see up to eight LUNs per FC host port, t he host will not be able to see the virtual

69
Page 70
devices numbered LUN8, LUN9, ..., and up. LUN masking limits the virtual devices (LUNs) the host’s
operating system can see on the port, so that only the virtual devices the host needs to see are visible.
To perform LUN masking:
1. Open a Command View VLS session and log in as the administrator. See Opening a Command
View VLS session from Command View TL.
2. Click the System tab.
3. Select Chassis in the navigation tree.
4. Click Host LUN Mapping Mode in the task bar.

LUN mapping is by host and is used to allow host access to hosts that are LUN masked, and to present

6. When you are finished making changes, click Apply Settings.
7. Repeat these steps for the rest of the virtual libraries and tape drives configured on the VLS that

CAUTION:
Each virtual device must be assigned a unique LUN number on the FC host port to which it is mapped. If
two virtual devices have the same LUN number on the same FC host port, the virtual device with the
lowest virtual device ID number assigned by the VLS is recognized as that LUN number by the host’s
operating system. The other virtual device is ignored by the operating system.

Dual port virtual devices
When creating a library robot LUN or tape drive LUNs, you can present the virtual devices to a pair of
host ports rather than just one port. Both ports must be on the same node. The Port Mapping drop-down
box displays selections for each individual port plus possible port pairs (for example: 0, 1, 0&1). The
benefit of dual port virtual devices is that they are still accessible when one path fails.
CAUTION:
Many operating systems and backup applications do not support more than one path to a tape library
device. Only use this feature if you are cer tain that it is supported.
HP StorageWorks
71
Page 72
When creating dual port virtual devices, the LUN numbering on both por ts follows the conventions for
default LUN numbering (see Default LUN numbering); however, if you use LUN mapping for a dual port
device (see LUN mapping), the defined LUN number for that device for a specified host applies to both
device paths. Follow the operating system LUN requirements (see Operating system LUN requirements
and restrictions)whenconfiguring the paths.

Destroying a tape drive
NOTE:
Destroying a tape drive may create a gap in the default LUN numbering on the FC host port to which it
was mapped. If a gap is created, restart the VLS device emulations to remove the gap. See Restarting the
VLS device emulations.
Most operating systems will ignore (cannot access) any virtual devices with LUN numbers that follow a
gap in the LUN numbering on an FC host port.

Managing high availability
Array dual pathing
The VLS300 supports dual pathing to the disk arrays, which provides path balancing and transparent path
failover on the VLS300. Having followed the setup recommendations in the HP StorageWorks 300 virtual
tape librarie
connected to
This assures that the gateway can establish t wo paths per LUN, each path on a separate fabric/zone.
Load balancing
For load balancing, half of the data transfer (from a specific node through a fabric to the external array)
is conducted over one path; half over a second fabric, hence another path. The paths are selected as
follows: Once configured, the device recognizes all paths to each node on the device. From all potential
preferred paths and all potential secondary paths (see Step 3), the a rray assigns one preferred path and
one secondar y path.
s solutions guide and the installation instructions in this guide, each node on the VLS300 is
two fabrics/zones which are each connected to the external arrays by two or more paths.
NOTE:
During each reboot the device is re-analyzed and the preferred and secondary paths are reassigned.
To view the preferred path for each LUN in the Storage LUN Details:
1. In Command View VLS, select the System tab.
2. Select Storage LUNs in the navigation tree.
3. Select the View button for either All LUNs or the LUNs in the desired <Storage Pool #> (Figure 55).
Summary information displays at the top of the list. Preferred and secondary paths are listed after
the summary information in the Storage LUN Details Per Node sections.
NOTE:
It may take several minutes to display this information if there are many LUNs.

LUN path failover
LUN path failover allows the VLS300 to automatically reroute data traffic usually assigned to one
(preferred) path to another (secondary) path when the preferred path fails. Path status is shown in
Command View VLS under Storage LUN Details.
A failover is indicated in the Storage LUN Details screen by the yellow warning icon and the notification
message: Fibre Channel Path Failed Over to {#:#:#:#}. The #s stand for the nod e port; bus number
(always 0) ; the target id (an EVA port) ; and the LUN number on the EVA.
When one path fails, automatic failover reroutes data traffic to the secondary path so the data transfer
still happens, but potentially at a slower rate. It is advised that you restore the path as soon as possible to
avoid a double path failure.
To restore the failed path:
1. Determine the cause of the failure and repair it if needed.
2. In Command View VLS, access the System tab.
3. Select Storage LUNs from the navigation tree.
4. Select View to display the storage LUN details.
5. Select Fix Primary Paths from the task bar to display the Fix Primary Paths Wizard (Figure 56).
HP StorageWorks
89
Page 90
Figure 56 Fix Primary Paths Wizard window
6. Select App ly to set all paths back to their primary paths.
Failure of both paths (double path failure) is indicated by the red critical icon and a specificnotification
message. The notification message differs based on whether the failure occurs while running or upon
booting the system (Figure 57).
Figure 57 Notifications window
• A double path failure that occurs while running results in the critical alert Fibre Channel Paths
Failed for Lun, ulid <numerical LUN id number> wwnn <numerical wwnn>.
• A double path failure that occurs upon booting the system results in the critical alert Missing
Storage LUN paths on node #.
This means the node can not communicate with the LUN at all. If the failed paths are on the primary
node, the whole storage pool containing tha t LUN is off-line; if the failed paths are on a secondary node,
the storage pool is on-line until reboot, but the storage pool is inaccessible from that node. In this case,
you can still get to the LUNs, b ut only from a different node.
To repair double path failure (assuming there has been no reboot during the failure):
1. Determine the cause of the failures and repair them if needed.
2. In Command View VLS, access the System tab.

3. Select Storage LUNs from the navigation tree.
4. Select Fix Primary Paths from the task bar to display the Fix Primary Paths Wizard.
5. Select Apply to set all paths back to their original settings.
CAUTION:
If you attempt to reboot during a path failure without first repairing the failure, the array might reassign
paths or fail-over preferences. This will limit device performance because all data trafficwillberouted
through a single controller. To restore performance, from Command View EVA:
Reset path fail-over preferences for each LUN to no preference.
1.
Save the presentation.
2.
Reset the path fail-over preferences back to their original values.
3.
Save the presentation.
4.
Reboot the VLS system.
5.
Private LAN dual pathing
The private LA N on the VLS300 has dual pathing which consists of a cable from each switch to each
node. If a LAN switch or a path to a LAN switch fails, the data transfer will automatically fail-over
to the other available switch.
• The primary path is through NIC 2 of the switch and is referred to in the error notification as eth1.
If the LAN switch associated with NIC2 fails, the Notifications tab will display all eth1 failures.
• The secondary path is through the USB LAN cable and is identified as eth2 in the error
notification. If the LAN switch associated with the USB LAN cable fails, the Notifications tab will
display all eth2 failures.
• If both paths fail, the critical alert will identify bond 0 as the combined failed path. If both
paths from the private LAN to a secondary node fails, the node is off-line; but if both paths to a
primary node fails, the whole device is off-line.
When a failure occurs, repair the failure. In most cases, the system will automatically recognize that the
repair is complete and restore the path or paths without having to reboot the system; however, you may
need to reboot the system if the repair includes installing a new USB LA N adapter.

Freeing up storage space
Storage space can be freed up by erasing the data on or destroying virtual media that is no longer
used, such as:
• Car tridges that are no longer used by a backup application
• Car tridges that have been moved to the Firesafe that are no longer needed
Use the backup application to erase data on virtual media that is no longer used.
Destroy virtual media that is no longer needed using Command View VLS. See Destroying cartridges.
NOTE:
Reducing the size of the cartridges in a virtual library will not free up disk space. Storage space is
dynamically assigned by the VLS as it is used. It is not reserved.
Restarting VLS device emulations
Restart VLS device emulations:
• If the VLS locks up
• After destroying a virtual device (library or tape drive) on the VLS and doing so leaves a gap in
the virtual device LUN numbering on an FC host port
• After adding a virtual tape d rive and the default LUN number assigned to it is not consecutive
with the other virtual tape drives in the same library
• After deleting external array LUNs.
CAUTION:

Saving configuration settings
NOTE:
The VLS software ensures a persistent VLS serial number and FC port WWPNs, so that in the event of
any hardware failure and replacement (such as the system board or FC host bus adapter card), the VLS
still appears exactly the same to the external SAN. It does this by generating a VLS serial number and
FC port WWPNs at first boot, which are based on the system board’s MAC address. The VLS serial
number and FC port WWPNs are saved on the VLS hard drives and with the virtual library configuration
settings in the configu ration file.
HP highly recommends that you save your virtual library configu ration and the VLS network settings to an
external configuration file, so they can be restored in the event of a disaster.
To save your virtual library configuration and the VLS network settings to an external configuration file:
1. Open a Command View VLS session and log in as the administrator. See Opening a Command
View VLS session from Command View TL.
