1 Introduction The HP 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. Firmware version 6.0.0 marked the change to a 64–bit operating system on the nodes.
Up to six nodes can be added to a Gateway for a total of eight nodes in a single Gateway. You can increase capacity by purchasing capacity licenses, each of which adds licensing for one additional external array LUN and increases maximum external capacity by up to 2 TB. Adding nodes and licenses increases the Gateway storage capacity as shown in Table 1 (page 11). Adding nodes also increases the performance. See the HP StorageWorks VLS12200 Virtual Library System Quickspec on the HP web site (http://h18006.
2 Hardware Installation This section details the steps to install the VLS hardware from installation preparation to final cabling. Minimum Hardware Requirements VLS12000 systems upgrading to firmware 6.
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.
• ◦ Cabling servers in a rack ◦ Coupling multiple racks The Rack Products Documentation CD enables you to view, search, and print documentation for HP and Compaq branded racks and rack options. It also helps you set up and optimize a rack in a manner that best fits your environment. Rack Requirements HP supports the HP System E racks and the HP 10000 Series racks for use with VLS systems. Other racks might also be suitable, but have not been tested with the VLS.

Item Description 6 Printed VLS node installation poster (1) Ethernet cables (2), not shown (shipped separately) Installing the VLS Node into a Rack NOTE: If you are installing the node into a telco rack, order the appropriate option kit at the RackSolutions.com web site: http://www.racksolutions.com/hp. Follow the instructions on the web site to install the rack brackets. 1. 2. Locate the rail kit, part number 360332–003. Install the two outer slide rails to the rack.
NOTE: If your rack contains single phase PDUs: • Install up to four nodes in the first rack starting in position 35 working up the rack. • Install up to four nodes in the second rack starting in position 35 working up the rack. If your rack contains 3–phase PDUs: • Install up to six nodes in the first rack starting in position 33 working up the rack. • Install up to two nodes in the second rack starting in position 33 working up the rack.
2. If you are installing more than two nodes, cable the nodes using Table 2 (page 17). Start at node 2 and work your way up the rack. 3. 4. Using Velcro®, secure the cables to the left side of the rack. Install loopback plugs on the nodes in all unused Fibre Channel ports. IMPORTANT: Do not touch the Fibre Channel cable tips. Do not secure Fibre Channel cable with cable ties.
Installing Cage Nuts and Rail Flanges 1. On the rack vertical posts, mark the holes (three on each front vertical post and two on each rear vertical post) that will be used by the rail flanges. Then, from the inside of each vertical post, insert a cage-nut into each marked hole. 2. From the front of the rack, secure the mounting flanges to the marked holes, using screws shipped with the rails. Attach a washer and nut to the posts at the end of each mounting flange.
Mounting Ethernet Switch 6600-24G into the Rack 1. At rack position 39, from the back of the rack align the grooved ends of the switch rails with the posts on the mounting flanges. Placing the grooved ends between the mounting flange and the loose washer and nut provides guidance. 2. 3. Slide the switch fully into the rack. Tighten the washer and nut on both sides of the rack to secure the switch rails to the mounting flanges.
Cabling Ethernet Switches 6600–24G 1. Connect an Ethernet cable from port 24 on switch #1 to port 24 of switch #2. 2. Using Velcro®, secure the excess cable to the right side of the rack. WARNING! Do not connect cables to unused ports on Ethernet switch #1 or #2. Doing so could result in data loss.
3 Multi-node Setup This section explains how to configure the identities of each node after the nodes and other components of the system are installed and cabled. NOTE: nodes. The Fibre Channel and Ethernet switches should be powered on before configuring the NOTE: The VLS system can be configured remotely using iLO with virtual terminal or virtual media; see the iLO user guide for details. Configuring the Primary Node 0 To configure the primary node: 1.
6. Repeat this procedure for each secondary node in the system.
4 Storage Configuration This section describes how to configure the storage after the nodes have been configured. Establishing Communication Between the VLS12000 Gateway and the EVA This section describes how to establish communication between the VLS12000 Gateway and the EVA by adding hosts and ports to the EVA and then presenting the LUNs. Verifying Array Zoning Verify that you have configured the zoning between the EVA ports and all storage ports on all the nodes of your VLS Gateway.
d. Enter the Host name (preferably the VLS hostname), enter or select one of the WWPNs (noted in the previous step) in the Port WW Name box on the VLS Gateway, and select Linux for the Host OS (Figure 3 (page 25)). NOTE: If a WWPN is not in the Port WW Name box, there may be a zoning error. After creating the host entries, verify that your zoning is correctly configured. Figure 3 Add a Host window e. f. g. h. Click on Add Host. From the Storage tab navigation tree, select the host you just added.
3. Present the LUNs: CAUTION: Present only the disks that you wish to use with the VLS Gateway because existing data will be destroyed during storage pool configuration. a. b. c. d. In Command View EVA, in the Storage tab navigation tree, select the EVA for the VLS Gateway storage system, Virtual Disks, the disk name that you want to present, then ACTIVE under that disk. Select the Presentation tab. Ensure that Write Protect is set to No.
• Destroy storage pools. See Deleting Array LUNs • Enable device-side data compression when creating new tape drives. See Creating Tape Drives (page 96) Discovering Array LUNs 1. Discover the LUNs, either by rebooting the entire VLS Gateway or: a. Open a Command View VLS session and log in as the administrator. See Opening a Command View VLS Session from a Web Browser (page 77). b. In the Storage tab navigation tree, select Storage LUNs. c. Select Discover Unconfigured Storage from the task bar.
Deleting Array LUNs CAUTION: Deleting an EVA LUN that is part of an existing storage pool will result in the loss of all cartridge data for that storage pool. To remove a LUN from the device: 1. Unpresent the LUN to the VLS (see instructions below) or delete the LUN from the external array. 2. Restart emulations or reboot the device (see Restarting VLS Device Emulations (page 106) or Rebooting the System (page 74)). 3. Discover unconfigured storage (see Discovering Array LUNs).
Configuring Storage Pools VLS automatically creates one storage pool. HP recommends that a single storage pool is used even for multiple arrays. However, if additional pools are needed, you must create them. To do so: NOTE: The VLS Gateway can have either one storage pool for all LUNs, or one storage pool for each array. Refer to the solutions guide for details. 1. Create a storage pool(s): a. Open a Command View VLS session and log in as the administrator.
NOTE: Do not format the LUNs when manually creating previously existing pools after performing a disaster recovery of the primary node. If you do not format the LUN, all cartridge data in that pool is retained. f. 3. Click Finish to add the LUNs to the pool. If you started with an unconfigured device (i.e., no LUNS added to any storage pools) before you added LUNs to the storage pools, you need to reboot the device to enable the new storage pools. The pool is now ready to have cartridges created.
4. Select Next to destroy the pool. A second page of the Confirm Destroy screen is displayed, containing the following text: WARNING: Existing data in StoragePool # will be destroyed and cannot be recovered. This step cannot be reversed. 5. 6. Select Finish to display the screen confirming that the storage pool has been destroyed. Select Finish again to return to the system screen.
• Secure Erasure: When you delete a cartridge, this feature overwrites deleted cartridge data with a specific data pattern so the data cannot be recovered. This is comparable to tape shredding of physical tapes. This only applies to firmware version 6.0 and higher. • iLO 2 Advanced VLS nodes are shipped with the HP Integrated Lights-Out (iLO) Standard feature for remote management. However, you need a license to use the iLO 2 Advanced features including Virtual Media and Remote Console.
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 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.
Replication can be configured to operate in one of two modes: • Deduplication-enabled replication, known simply as 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.
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.
1. Select the Automigration/Replication tab. The Summary for All Managed Destination Libraries screen displays. 2. 3. 4. 5. 6. 7. Select Manage LAN/WAN Replication Library from the task bar. Enter the name or IP address of the host containing the LAN/WAN replication target you just created. Select Submit. On the next screen, select the LAN/WAN replication target to manage. Enter the password you created for that target. Select Submit. The LAN/WAN replication target is now associated with the source.
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. 4. Select Submit.
5. of the mirror by using a Command View VLS Console and viewing the destination tapes in Slots in the expanded list under Destination Library. 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.
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.
LAN/WAN libraries: • Priority — the priority this echo copy pool takes over other copy pools during the backup window. This can be High, Medium, or Low. • 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.
NOTE: The tape is only created if a header exists and is legible by the system. Restoring from a SAN Physical Cartridge If the destination tape is still loaded in the destination library, then its matching virtual cartridge will still be present in the virtual library. In this case, you can simply restore from the virtual cartridge using the backup application. If the destination tape has been ejected from the destination library, you must use one of the following options: 1.
Restoring from a LAN/WAN Virtual Cartridge From Command View VLS: 1. Click the Automigration/Replication tab. 2. Under Destination Libraries in the navigation tree, expand the library you want to restore. 3. From the navigation tree, select Slots. 4. On the task bar, select Restore Media. 5. Select the slot numbers you wish to restore. 6. Click Submit. The Restore Media screen refreshes with a message that indicates the restores were successful.
4. 5. 6. From the task bar, select Load Media for Overwrite to open the Load Media for Overwrite screen. From the drop-down box, select the copy pool you want to load the media into. For all mailslots, the destination slots are automatically populated with the first available slots. To keep the automatic assignment, skip to Step 10. To assign the destination slots manually, continue to the next step. If the Destination Slot Number for each mailslot displays “None,” the copy pool you selected is full.
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.

6 Deduplication Deduplication is the functionality in which only a single copy of a data block is stored on a device. Duplicate information is removed, allowing you to store more data in a given amount of space and restore data using lower bandwidth links. The HP virtual library system uses Accelerated deduplication. This section describes deduplication including getting deduplication running on your system, configuring deduplication, and viewing reports.
entire backup job and to prevent too many backup jobs from piling up on the same cartridge, but small enough that you are not wasting overall cartridge space. • Additional nodes — For systems with long backup windows, you may want to include additional nodes to speed up the post-processing deduplication. A VLS system using deduplication can support up to six nodes nodes.
NOTE: Once you change the algorithm from Backup to Enhanced Backup, you cannot revert to Backup again. However, you can still disable the policy. 4. • Enabled — Available if the algorithm is currently set to Disabled. • Disabled — Turns off deduplication.

Click Apply Settings. Editing the Default Fibre Channel Host Port Settings Only edit the Fibre Channel host port settings if you do not want to use the default settings, if some system problem is occurring, or if the “AUTO” setting is not working properly.
Enabling and Disabling Oversubscription To enable oversubscription: In Command View VLS: 1. Select the System tab. 2. Select Chassis in the navigation tree. The chassis details window opens. 3. 4. In the Oversubscription section, select Enabled. The Notify when storage capacity is [x] % Full box defaults to 90. You may change the value or leave it at 90. This percentage value is the threshold of storage space consumed that when reached triggers a storage capacity notification alert.
Reclaiming Storage Space The Reclaim Space task appears on the Chassis status screen when the storage capacity consumed reaches the user-defined threshold (or the default of 90%). This allows you to schedule reclamation of the additional storage you make available by erasing cartridges. First erase cartridges from your backup application, then follow the procedure below. From Command View VLS: 1. On the System tab, select Chassis from the navigation screen to open the Chassis status screen. 2.
Operating System LUN Requirements and Restrictions Most operating systems require that each VLS Fibre Channel 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 Fibre Channel 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.
Setting the Default LUN Mapping You can set a global default to disable or enable LUN mapping. The setting you choose will apply to every new host that you add to the VLS. • All Devices (LUN mapping disabled) – The default. The VLS allows all hosts connected to the VLS through the SAN to access all virtual devices configured on the VLS.
5. Select a library from the Choose a Library list to view its mapped devices. The window refreshes to show the appropriate list. 6. 7. 8. Use the View By list to narrow the list of devices based on the node. Select the devices you want to map to a particular host. Select the host in the Choose hosts list at the bottom of the window. These hosts currently do not have any of the devices shown mapped to them. You can select multiple hosts using Ctrl+click. 9. Select Map next to Choose hosts.
NOTE: After you map or unmap the virtual devices, the VLS automatically reassigns a logical unit number (LUN) to each virtual library and tape drive created on the VLS to ensure that the virtual device LUN numbering meets the operating system LUN requirements. Setting Up the Hosts You can configure the hosts in Command View VLS. You will make all of the changes to the hosts from the Host Setup window. To open the Host Setup window: 1. Select the System tab. 2. Expand Chassis in the navigation tree. 3.
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 list 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.
Figure 12 Create Virtual Library Wizard window (2 of 12) 7. 8. Change the library name if you prefer. You can use letters, numbers, and underscores (no blank spaces). Enter the maximum number of cartridge slots that may be added to the library in the Maximum Slots box. The default values in the Maximum Slots box is based on the physical tape library you selected.
Editing a Virtual Library To edit the slots and drives of a virtual library, from Command View VLS: 1. Click the System tab. 2. Expand Chassis in the navigation tree. 3. Expand Virtual Libraries in the navigation tree. 4. Select the virtual library you want to edit. 5. Select Edit Virtual Library in the task bar. 6. On the Library Parameters screen, change the values as appropriate. You can change the maximum number of slots, maximum number of ports, and maximum number of drives. 7. Select Next Step.
8. Choose one of the following options: • To perform LUN mapping for the virtual tape drive, click Map LUNs and proceed to “LUN Mapping” (page 90) for further instructions. • To create more tape drives, click Create More Tape Drives. • To add cartridges to the virtual library, click Create Cartridges and proceed to “Creating Cartridges” (page 97). • To exit the wizard, click Cancel. At this point the library and tape drives have been created, but the library does not contain any cartridges.
NOTE: NetBackup has total barcode limit of eight characters. HP Data Protector has a total barcode limit of 16 characters. Check your user guide for other backup applications. 5. 6. 7. 8. Click Next Step. Select the type of physical cartridge to emulate. Click Next Step. Enter the number of cartridges and the cartridge size in the appropriate boxes (Figure 14 (page 98)). The default number of cartridges is based on the maximum number of slots configured for the virtual library.
NOTE: You cannot destroy a library that is currently being accessed by a backup application. When a virtual library is destroyed, all the tape drives associated with the library are also destroyed. The cartridges in the virtual library, however, are not destroyed. They are moved to the Firesafe where they are stored until you either destroy them or associate them with a virtual library. See “Managing Cartridges” (page 102). To destroy (delete) a virtual library, from Command View VLS: 1.
10 Management This section details the VLS management procedures such as changing the account passwords, managing high availability, and saving configuration settings. Changing the Account Passwords To change the administrator and/or user account password, from Command View VLS: 1. Click the System tab. 2. Select Chassis from the navigation tree. 3. Click Edit Accounts under Maintenance Tasks. The Edit Accounts window opens. 4. Enter the current password in the Old Password box.
LUN Path Failover LUN path failover allows the VLS 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 {#:#:#:#}.
Private LAN Dual Pathing The private LAN on the VLS 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.
7. Click Update in the cartridge row. Changing Cartridge Read and Write Access To change a cartridges' read and write access, from Command View VLS: 1. Click the System tab. 2. Select Cartridges in the navigation tree. The Cartridge Details screen opens. 3. Select the number of cartridges to display from the menu beside the category of cartridges you wish to move. The options are 10, 50, 100 (default), 500, or 1024 cartridges. 4. Click View beside the category. The cartridges parameters window opens. 5.
Deleting Cartridges You can delete one or more cartridges at a time from the VLS. The delete cartridge operation removes the specified cartridges from the VLS, freeing the storage space previously consumed by those cartridges for new data. For more security, you can use the licensed Secure Erasure feature. Secure Erasure provides guaranteed erasure of information on virtual tape cartridges. (You must purchase a separate license for this feature.
4. Click Yes to continue. (You can click No or Cancel to return to the Cartridge Details screen without deleting any cartridges.) The system deletes the selected cartridges, and the progress of the delete operation is indicated on the Destroy Cartridge wizard. Secure Erasure occurs in the background after a cartridge is deleted. When the delete operation is complete, a success message appears. 5. Click Finish to exit the wizard and return to the Cartridge Details screen.
Destroy virtual media that is no longer needed using Command View VLS. See “Destroying Cartridges” (page 104). 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.
10. Select Accept and Install to continue. The screen displays a message that the upgrade was successfully installed and reboots automatically. The reboot may take several minutes. Saving Configuration Settings NOTE: The VLS firmware ensures a persistent VLS serial number and Fibre Channel port WWPNs, so that in the event of any hardware failure and replacement (such as the system board or Fibre Channel host bus adapter card), the VLS still appears exactly the same to the external SAN.
11 Monitoring This section describes the various tools you can use to monitor the status of the VLS hardware and virtual devices (libraries and tape drives) and how to use them. Status Information in the Status Pane Status information for the VLS hardware components and virtual devices is displayed in Command View VLS on the status pane when an individual hardware component or virtual device is selected in the navigation tree.
Figure 15 Device status icon in the status banner A device status icon can be one of four states: Unknown—A component's operating condition is unknown. Contact HP Technical Support. Normal—All components within the VLS are operating normally. Warning—A component's operating condition has degraded. Error—A component has failed. Navigation Tree Icon An icon appears just to the left of objects in the navigation tree when an unknown, warning, or error condition is present with a component.

The grounding plug is an important safety feature. • Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times. • Unplug the power cord from each power supply to disconnect power to the equipment.
Removing a VLS Node from the Rack To remove the node from a rack: 1. Power off the node. See Powering Off the System. 2. Disconnect the cabling. 3. Extend the node from the rack. See Extending a VLS Node from the Rack. 4. Remove the node from the rack. For more information, refer to the documentation that ships with the rack mounting option. 5. Place the node on a sturdy, level surface.
2. Pull the hard drive (3) out of the node by the latch handle (2). Figure 28 Removing a Node Hard Drive To replace the component, pull out the latch handle (2) out as far as it can go and slide the drive into the bay until the latch mechanism engages the chassis. Then, firmly push in the latch handle to lock the drive in the drive bay.
DVD-CD Drive CAUTION: To prevent improper cooling and thermal damage, do not operate the node unless all bays are populated with either a component or a blank. 1. Power off the node. NOTE: The ejector button for the CD-ROM drive is recessed to prevent accidental ejection; it may be helpful to use a small, flat, blunt object, such as a key or pen, to push the ejector button. 2. Press the ejector button in firmly until the DVD-CD drive ejects (1). 3. Pull the DVD-CD drive out of the node (2).
2. Press the power supply release lever (1), and then pull the power supply from the node. To replace the component: WARNING! To reduce the risk of electric shock or damage to the equipment, do not connect the power cord to the power supply until the power supply is installed. 170 1. 2. Remove the protective cover from the connector pins on the power supply. Slide the power supply into the bay until it clicks. 3. Use the strain relief clip to secure the power cord. 4. 5. 6.
Fan Module CAUTION: Do not operate the node for long periods without the access panel. Operating the node without the access panel results in improper airflow and improper cooling that can lead to thermal damage. 1. 2. 3. 4. Power off the node. Extend or remove the node from the rack. See Extending a VLS Node from the Rack or Removing a VLS Node from the Rack. Remove the access panel. To remove fan module 1: a. Remove the power supply air baffle. b. Remove fan module 1.
5. To remove fan module 2 or 3: a. Remove the power supply air baffle. b. Remove fan module 2 or 3. To replace the component, reverse the removal procedure. IMPORTANT: After installing the fan module, firmly press the top of the module connectors to ensure the connectors are seated properly. FBDIMM 1. 2. 3. 4. 5. Power off the node. Extend or remove the node from the rack. See Extending a VLS Node from the Rack or Removing a VLS Node from the Rack. Remove the access panel. Open the FBDIMM slot latches.
NOTE: FBDIMMs do not seat fully if turned the wrong way. When replacing a FBDIMM, align the FBDIMM with the slot and insert the FBDIMM firmly (1), pressing down until the FBDIMM snaps into place. When fully seated, the FBDIMM slot latches (2) lock into place. Replacing a Primary Node CAUTION: Each VLS node weighs 17.9 kg (39.5 lb) full. At least two people are required to lift and move each node. To replace a primary node: 1. Remove the existing node from the rack: a. Power off the system.
a. b. On the primary node, connect to the serial port or use the keyboard and mouse ports to connect to a console. 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. c. d. Enter m. The node will then run cable checks and configuration checks. After the checks are complete the node will reboot automatically. Wait for the primary node to fully boot.
3. 4. Stop any in-process backups and restores, and disable the VLS in the backup applications to suspend operations during the node replacement. Create a firmware version 6.1.0 Quick Restore DVD. Having one DVD for each node will speed up the Quick Restore process. To replace the nodes: 1. Attach rails to all of the replacement VLS9200 nodes; see the instructions in the rail kit. 2. As a best practice, save the configuration on the live VLS system. 3. Shut down all VLS nodes.
15 Disaster Recovery This section details the VLS disaster recovery procedures. It includes recovering from operating system failures, disk array failures, and node failures. Recovering from Operating System Failure Re-install the operating system if it becomes corrupted or is lost as a result of node RAID volume failure. CAUTION: Only install the VLS operating system on the node hard drives. Installing any other operating system on the node hard drives voids the warranty.
Manually Restoring the System After re-installing the operating system, the warm failover feature restores the licenses and configuration settings. However, if the warm failover does not occur (for example, due to a corrupt or missing file), the VLS virtual library configuration and network settings can be quickly restored from the configuration file created by performing a Save Configuration. See Restoring the Configuration from a Configuration File.
7. 8. 9. Click Open. Click Next Step. A message displays indicating that the file was uploaded successfully. Click Next to start loading the configuration file. After the configuration file is loaded, the system automatically applies the configuration and reboots. Manually Rebuilding the Virtual Library Configuration If you are unable to manually restore the system from the configuration file, you must manually reconfigure the network settings and rebuild the virtual library configuration: 1.
To deploy the spare primary node: 1. Shut down all nodes on the VLS. Because the original primary node has failed, he secondary nodes should be shut down from the command line of each node. Log in to the administrator account on each secondary node using the serial port or keyboard and mouse. At the prompt, enter shutdownNode. 2. Cable the spare primary node exactly as the original primary node was cabled: a.
IMPORTANT: If you do not present EVA virtual disks to the new primary node, the warm failover will fail to restore the configuration. You must Quick Restore the node and start over. 5. Enter m. The node will then run cable checks and configuration checks. After the checks are complete the node will reboot automatically. Wait for the node to fully boot. The new primary node will reboot once more after it has retrieved the old configuration from the backend storage.

A Troubleshooting This appendix lists iLO troubleshooting features, and also describes some common issues you may encounter while configuring or using the VLS including automigration/replication and deduplication issues. Using iLO The VLS supports many of the features of iLO 2 Standard (non-licensed). If you are troubleshooting the VLS, especially if the system is down, you may find these features helpful: • Power on the VLS. • Power off the VLS.
Symptom Possible causes Solution virtual devices the host can see, such that the virtual device LUN numbers include a LUN0 and no gaps in the LUN numbering. See LUN Masking and LUN Mapping for instructions. There is a gap in the LUN numbering on the FC host port. Most operating systems will stop looking for virtual devices on an FC host port once a gap in the LUN numbering is detected. For example, if LUN0, LUN1, and LUN3 are mapped to an FC host port, the operating system will see LUN0 and LUN1.
Symptom Possible causes Solution Netbackup does not display the cartridge barcodes for Autoloader library emulations on the VLS. Real autoloader libraries do not support barcodes. This is normal and will not cause problems. HP Data Protector 5.1 does not display the VLS cartridge barcodes. By default, the barcode reader support To turn on barcode reader support in is turned off in Data Protector 5.1. Data Protector: 1. Click Device & Media. 2. Right-click the VLS library name and select Properties.
Symptom Possible causes Solution 4. Check Increase performance by disabling support for Microsoft Backup Utility. 5. Repeat this procedure for each server visible to each SDLT tape drive. At reboot, there are spurious critical This is expected behavior and does FC port failures reported as not indicate a problem. notification alerts, usually on every port. Later, Info notification alerts for each FC host port are generated, indicating the FC ports are operating normally.
Deduplication Issues Symptom Possible causes Solution The VLS is not deduplicating the backup jobs. The VLS does not free up storage on a cartridge until: Consider using cartridges that are smaller than the sum of your daily backup jobs so the cartridges deduplicate sooner.

Glossary This glossary defines terms used in this guide or related to this product and is not a comprehensive glossary of computer terms. A Accelerated deduplication A method of deduplication that uses object-level differencing technology. See also deduplication.. appliance An intelligent device programmed to perform a single well-defined function.
deduplication The process of eliminating duplicate data from the backups on a virtual cartridge to reduce the amount of disk space required. disk array Two or more hard drives combined as a single logical unit for increased capacity, speed, and fault-tolerant operation. Disk arrays are logically grouped into a storage pool. disk mirroring Also known as data mirroring.
inputs/outputs per second A performance measurement for a host-attached storage device or RAID controller. L library A storage device that handles multiple units of media and provides one or more drives for reading and writing them, such as a physical tape library and virtual tape library. Software emulation of a physical tape library is called a virtual tape library. See also virtual tape library.. logical unit number (LUN) An address used in the SCSI protocol to access a device within a target.
RAID1-level data storage A RAID that consists of at least two drives that use mirroring (100 percent duplication of the storage of data). There is no striping. Read performance is improved since either disk can be read at the same time. Write performance is the same as for single disk storage. RAID5-level data storage A RAID that provides data striping at the byte level and also stripe error correction information. RAID5 configurations can tolerate one drive failure.
V virtual tape A disk drive buffer that emulates one physical tape to the host system and appears to the host backup application as a physical tape. The same application used to back up to tape is used, but the data is stored on disk. Also known as a piece of virtual media or a VLS cartridge. Data can be written to and read from the virtual tape, and the virtual tape can be migrated to physical tape.
