Figure 1 Library Extender installed with two MSL4048 Tape Libraries The extender occupies the lower half-height drive bay of the upper library and the top half-height drive bay of the lower library. The upper library controls the extended library and is called the master library. The extended library uses only the master library OCP, USB port, and Ethernet connection. The lower library is controlled by the master library.
Figure 2 RMI Configure: License Key screen After you order the upgrade license, you can access the additional slots immediately by generating a temporary license key. The temporary key can only be enabled once and is valid for 30 days. NOTE: The temporary key is intended to provide instant access to the upgrade capabilities until you receive the permanent key. The temporary key expires after 30 days.
2. Click Generate Temporary LTFS License. NOTE: Download the LTFS software before generating the temporary LTFS license. To apply the permanent license: 1. Navigate to the RMI Configuration: License Key screen. 2. Enter the license key and then click Submit. The permanent license takes effect when the library is rebooted. Interface specifications and requirements for parallel SCSI drives The parallel SCSI libraries use the Ultra 320 SCSI LVD interface.
Figure 3 MSL2024 default SCSI IDs 1. Default SCSI ID 4 2. Default SCSI ID 5 • MSL4048: The default SCSI ID for the bottom drive of each pair is 4 and for the top drive is 5 as shown in Figure 4 (page 15). Figure 4 MSL4048 default SCSI IDs 1. Default SCSI ID 4 2. Default SCSI ID 5 • MSL8048 and MSL8096: The default SCSI address for all tape drives is 4 as shown in Figure 5 (page 15). Figure 5 MSL8048 and MSL8096 parallel SCSI tape drive default SCSI addresses 1.
Interface specifications and requirements for Fibre Channel drives The Fibre Channel tape drive can be connected directly to the server with a host bus adapter (HBA) or through a storage area network (SAN). Table 7 FC drive interface speeds LTO generation Supported speeds LTO-4 1 Gb, 2 Gb, 4 Gb LTO-5, LTO-6 2 Gb, 4 Gb, 8 Gb If you plan to connect the library directly to the server, you will need a 2 Gb, 4 Gb, or 8 Gb Fibre Channel HBA. A 4 Gb HBA is recommended for LTO-4 tape drives.
Any of the four drive cable ends can be used for any of the tape drives. If you use a different cable, verify that the mini-SAS connectors on the tape drive end are keyed for location 4. CAUTION: High quality SAS cables rated at the transfer rate of the SAS components are required. Always verify that the SAS cable you are using is rated for the data transfer speed of the interface of your components.
To use the encryption kit, a key server token is inserted in the USB port on the back of the library, and encryption is enabled and configured from the RMI. The encryption kit supports your manual security policies and procedures by providing secure storage for encryption keys. Access to the key server tokens and their backup files is protected with user-specified passwords. You will need to create processes to protect the tokens and secure the passwords.
Logical libraries You can configure a tape library with multiple tape drives into logical libraries. Each logical library must contain at least one tape drive. Each logical library is configured independently, allowing use by different backup applications and with different backup policies. For example, one logical library could perform a backup operation for one department while the second logical library restores data for another department.
tape drives or up to four half-height tape drives. The MSL8096 supports up to four half-height or full-height tape drives.

reliability enhancements to the MSL2024, MSL4048, MSL8048, and MSL8096 Tape Libraries with LTO-5 and LTO-6 Fibre Channel tape drives. • Data path port failover where a standby path is configured for the data path to the tape drive and activated following link failures. • Library control path port failover where a second drive is configured to host a standby library control path that can be activated following link failures.
If drive hosting the library control path fails, the library web interface may be used to take the control path drive offline and the library control path identity (world wide names) and all settings, (such as reservations and prevent/allow settings), will be moved over to the alternate master drive automatically. When properly configured, the change is minimally disruptive to the host and does not require any configuration changes on the host or in the backup application.
Technology for data path port failover The HP LTO-5 and LTO-6 Fibre Channel tape drives configure both ports with identical worldwide names but only one port will connect to the fabric. By default the port that completes speed negotiation first will become the active port. If the ports on the drive are connected to different speed fabric the port connected to the highest speed fabric will typically complete speed negotiation first.
Figure 9 Logical view of traditional configuration 0. Fibre Channel node 1. Tape Drive at logical unit 0 2. Library at logical unit 1 Virtual library connection using NPIV When configured to use library control path port failover, the HP LTO-5 drive will use NPIV to connect the library and the drive to a Fibre Channel switch as two different devices.
With NPIV creating a virtual device on the switch port that the drive is connected, to both the tape drive and the tape library are shown by the switch as independent devices even though they are connected to the same physical port. As the library is presented to the host as an independent device it can be managed independently from the tape drive. In “NPIV virtual library connection” (page 25) the tape library contains two drives with both tape drives connected to a Fibre Channel switch.
port failover is also enabled. When control path port failover is enabled, the port type is required to be fabric so the port type selections are disabled. Figure 12 Enabling data path port failover Verifying data path port failover After data path port failover is enabled, verify the configuration in the Drive: Status screen, as shown in Figure 13 (page 28).
Figure 13 Standby and active ports After verifying that the configuration change was successful, verify that the hosts with access to the tape drive are still able to communicate with the drive. After verifying host access via the initial path a data path port failover may be forced by disconnecting the cable from the active port on the drive. The drive status display shows which drive port is active and which port is in standby.
Figure 14 Configuration: Drive screen showing control path failover configuration disabled “Configure library, control path failover configuration disabled” (page 30) and “Configure library, control path failover configuration available” (page 30) show the Configuration: System screen.
Figure 15 Configure library, control path failover configuration disabled In “Configure library, control path failover configuration available” (page 30) the configuration requirements for enabling control path failover have been met and the library has made the option for Enable Library Control Path Failover selectable as well as providing a selection for the “Alternate Drive for Library Control Path”.
Figure 17 Library world wide name displayed on the Identity: Library page • Hosts connecting to the library may need to be rebooted if the operating system does not support dynamic device detection. • Applications on hosts may need to be reconfigured to recognize the new library world wide name. Verifying control path failover After enabling control path failover, verify the configuration of both ports.

2 Installing the library This chapter contains the information you need to install and configure your library.
• Install application software and compatible drivers on the host computer. See the application software manuals for installation and configuration information. • For parallel SCSI libraries, make sure multiple LUN support is enabled on the HBA and operating system. See “Multiple LUN support” (page 14). Planning the parallel SCSI configuration If the host computer will have multiple parallel SCSI devices, you must decide how they will be configured into one or more parallel SCSI busses.
• MSL2024: For full-height tape drives the default SCSI address is 4. For half-height drives, the default SCSI address for the bottom drive is 4 and the default SCSI address for the top drive is 5 as shown in “MSL2024 parallel SCSI tape drive default SCSI addresses” (page 40). Figure 33 MSL2024 parallel SCSI tape drive default SCSI addresses 1. Tape drive with SCSI address 4 2. Tape drive with SCSI address 5 • MSL4048: For full-height tape drives the default SCSI address is 4.
HBAs, review the compatibility matrix on the Enterprise Backup Solutions website at: http:// www.hp.com/go/ebs. CAUTION: Do not connect the library to a SAS RAID controller unless the EBS matrix shows that the controller is qualified with the library. The server might not be able to boot when the library is connected to a non-supported SAS RAID controller.
World Wide identifiers A SAS tape drive is identified by a unique identifier called a World Wide Name (WWN) or World Wide Identifier (WWID). The library assigns the World Wide identifier to the drive bay. When a tape drive is replaced, the World Wide identifier is re-assigned to the new tape drive. The operating system tracks the World Wide identifier for the drive on each HBA channel. Each of the drive connectors on the fanout cable is associated with an HBA channel.

Unpacking the shipping container Before you begin, clear a level work surface near where you will place the library. CAUTION: If the temperature in the room where the device will be installed varies by 15º C (30º F) from the room where it was stored, allow it to acclimate to the surrounding environment for at least 12 hours before unpacking it from the shipping container. Unpacking the tape library: 1. Inspect the container for shipping damage.
Table 16 Maximum FC cable lengths (in meters) (continued) Drive Cable type 2 Gb 4 Gb 8 Gb All except LTO-5 HH OM3, OM4 0.5 - 300 m 0.5 - 380 m 0.5 - 150 m * The LTO-5 Ultrium 3000 half-height drive is shown as LTO-5 HH. For SAS libraries, you must provide a SAS cable with the correct connector for your HBA. HP recommends using a SAS fanout cable that connects up to four tape drives to the SAS HBA. (See “SAS cables and connectors” (page 41).
Mounting the device in a rack If you plan to set the MSL2024 or MSL4048 library on a table or rack shelf, skip this step and continue with “Installing the Tabletop Conversion Kit” (page 48). The MSL8048 and MSL8096 libraries must be installed in a rack with the supplied rails. WARNING! The MSL2024 tape library weighs up to 15.6 kg (34.3 lb) without media and up to 20.4 kg (44.9 lb) with media (24 cartridges). The MSL4048 tape library weighs up to 24.6 kg (54.1 lb) without media and up to 34.2 kg (75.
Figure 39 Installing the rails into the rack 3. For the MSL4048, MSL8048, and MSL8096 insert the clip nuts on the front of the rack in the locations shown. These will be used to secure the library to the rack. MSL4048 MSL8048 and MSL8096 1. Clip nut location 2. Rail screw location 3. Bottom of the library 4. U marker To install the device on the rails and into the rack: 1. Locate the captive screws on the front bezel (see “Securing the tape library to the rack” (page 48)).
3. From the front of the device, secure the front bezel to the rack using a #2 Phillips screw driver placed through the small holes in the mounting bracket to tighten the captive screws on each side of the device. Figure 40 Securing the tape library to the rack Installing the tabletop conversion kit The Rack to Tabletop Conversion Kit supports the edges of the library, but is not a structural top. IMPORTANT: installed.
1. Locate an appropriate vacant drive bay on the back of the library. • MSL2024: The first tape drive should be installed in the bottom drive bay. If the first tape drive is a half-height tape drive, you can install an additional half-height tape drive in the top bay. • MSL4048: The first tape drive should be installed in the bottom drive bay. Install each additional tape drive in the drive bay directly above the existing tape drives.
Figure 43 Installing a tape drive 3. Tighten the blue captive screws with your fingers to secure the tape drive to the chassis. Installing a redundant power supply If you have a redundant power supply for the MSL4048, MSL8048, or MSL8096 tape library, you can install it now or wait until the installation process is complete. To install the redundant power supply: 1. Verify that the power to the library is off and the power cord is not attached. 2.
5. If these pre-configured addresses will not be unique on a bus, you must change the SCSI ID of one or more tape drives. To change the SCSI ID: 1. Plug the power cord into the power connector on the back panel and then plug the cord into the power outlet. 2. From the front panel, push the round power button to power on the device. 3. From the front panel, set the new SCSI ID for any drives that must have a different SCSI ID.
4. Attach the terminator to the remaining parallel SCSI connector on the back panel of the tape drive if the library is the last or only device on the parallel SCSI bus. Otherwise, attach one end of a parallel SCSI cable to the remaining port and the other end to the next device on the parallel SCSI bus. Make sure the last device on the parallel SCSI bus is properly terminated.
2. If you are using a cable with a single connector on each end, attach the other end into the connector on the tape drive. If you are using a SAS fanout cable, attach one mini-SAS connector into the connector on each tape drive. The unused ends of the SAS fanout cable are single channel and not suitable for use with disk arrays. Use the other ends to connect tape drives, or coil and secure them to the rack to minimize stress on the connectors.
5. 6. 7. Plug in the host server and all attached devices. Power on any other devices you powered off earlier. Power on the server. Configuring the device Now that the library is connected to the host and powered on, configure it for your environment. To configure the library : 1. Set the administrator password.
2. Verify the connection between the library and the host: • Install the HP Library & Tape Tools Diagnostic/Installation Check Utility onto the host computer. This utility verifies that the unit is connected and communicating with the host server. It also verifies that the device is functioning and provides diagnostic information. Run the HP Library & Tape Tools Installation Check from the programs menu to verify your connections. L&TT is available without cost at www.hp.com/support/TapeTools.
To find the current firmware revision, visit the HP Support website: www.hp.com/support. If necessary, update the device firmware: • From the RMI, see “Determining and updating firmware ” (page 97). • From the MSL2024 OCP, see “Upgrading firmware (Support > Library FW Upgrade, Support > Drive FW Upgrade)” (page 120). • From the MSL4048, MSL8048, and MSL8096 OCP, see “Updating library and drive firmware (Support > FW Upgrade)” (page 139).
3 Tape cartridges and magazines This chapter explains which media to use with your library, and how to label and write-protect your tape cartridges. Careful labeling and handling of the tape cartridges will prolong the life of the tape cartridges and the tape library. Tape cartridges Use the Ultrium data and cleaning tape cartridges designed for your model of tape library. You can order data and cleaning cartridges at www.hp.com/go/storagemedia.
• Do not drop a cartridge. Excessive shock can damage the internal contents of the cartridge or the cartridge case itself, making the cartridge unusable. • Do not expose data cartridges to direct sunlight or sources of heat, including portable heaters and heating ducts. • The operating temperature range for data cartridges is 10 to 35º C. The storage temperature range is -40 to +60º C in a dust-free environment in which relative humidity is always between 20 percent and 80 percent (non-condensing).
IMPORTANT: Misusing and misunderstanding bar code technology can result in backup and restore failures. To ensure that your bar code labels meet HP's quality standards, always purchase them from an approved supplier and never print bar code labels yourself. To order bar code labels from an HP-authorized reseller: • In the United States, call 1-800-345-1518. • Elsewhere, see the HP website: www.hp.com, then click Contact HP to find locations and telephone numbers.

Insertion arrow Read and write compatibility HP Ultrium data cartridges are fully supported and compatible with HP Ultrium tape products (see “Backward read compatibility” (page 60)). Because HP Ultrium media is Ultrium logo compliant, it may be used with any other non-HP device that bears the Ultrium logo.
Magazines The device has removable magazines. Magazine access is password protected. For safety reasons, the robotic motion is stopped when a magazine is removed. The magazines can be released using the operator control panel (OCP), the remote management interface (RMI), or by a manual release. HP recommends that you release the magazine using the OCP or RMI. The magazine must only be removed manually when the OCP or RMI process has failed, or the device no longer has power.

The storage slots in the other magazines are renumbered accordingly.
Figure 56 MSL4048, MSL8048, and MSL8096 lower-left magazine slot numbering with mailslot enabled On the MSL8096, when the upper-right mailslot is enabled, the numbering of the storage slots in the other magazines is not affected. Mailslot numbering for the upper-right magazine when just the upper-right mailslot is enabled is shown in Figure 57 (page 63). When both mailslots are enabled, the mailslot numbers in the upper-right magazine are adjusted, as shown in Figure 58 (page 63).
4 Operating the tape library The tape library can be operated by the following methods: • Remote management interface (RMI) — this interface lets you monitor and control the library from a web page. You can access most library functions from the RMI. • Operator control panel (OCP) — this interface lets you operate the device from the front panel. • Host backup software — You can perform any functions provided by the backup software.

The following settings affect all of the logical libraries: • Mailslot Configuration Enabled (MSL2024, MSL4048, and MSL8048) — configures the mailslot in the lower left magazine as a mailslot or storage slots.
one slot; the MSL4048 and MSL8048 mailslot has three slots. Enabling the mailslot will reduce the total number of storage slots. The default is disabled. If the mailslot is enabled, all logical libraries will have access to the mailslot. If allowing all logical libraries access to the mailslot is a concern or all of the slots are needed as storage slots, disable the mailslot.
NOTE: Barcode labels longer than eight characters might scan incorrectly, especially if they are not high-quality labels. • Barcode Label Alignment Reported to Host — configures the end of the bar code label characters to report to the host application when reporting fewer than the maximum number of characters. For example, when reporting only six characters of the bar code label 12345678, if alignment is left, the device will report 123456. If alignment is right, the device will report 345678.
To further determine how you want tapes loaded into the tape drive while in Sequential mode, you can set the Loop and Autoload options. ◦ ◦ When Autoload mode is set, the device automatically loads the cartridge from the lowest-numbered full slot into the tape drive. It then follows standard sequential operation. After configuring Autoload mode, you must do one of the following for Autoload mode to take effect: – Power cycle the device from the front panel.
NOTE: When library control path failover is first enabled, the hardware address for the library will change. Windows example: Bus Number 0, Target ID 0, LUN 1 becomes Bus Number 0, Target Id 2, LUN 0 Linux example: /dev/sg3 HP MSL G3 Series 7.41 becomes /dev/sg5 HP MSL G3 Series 7.41 If the library detects a situation when it is necessary to remove the primary master drive or force a failover, power off the drive from the RMI Configuration: Drive 1 (LUN) screen.
• Speed — Automatic, 1 Gb/s, 2 Gb/s, 4 Gb/s, or 8 Gb/s. Only speeds supported by the drive are listed. The default is Automatic. • Port Type — Automatic, Fabric (N), or Loop (NL). Direct connected devices are typically Loop. Devices connected to a switch are typically Fabric. The default is Automatic. • Addressing Mode — addressing mode when the port type is Loop: Hard, Soft, or Hard auto-select. If the Addressing Mode is Hard, you must configure a fixed ALPA address that is unique on the loop.
Figure 79 Configuration: Network page You may change the: • Protocol version — selects the Internet Protocols that will be enabled. Select IPv4 only, IPv6 only, or both IPv4 and IPv6 protocols. The default is the IPv4 protocol only. • Host Name — enter the host name provided by your network administrator for the library. • Domain name — enter the domain name provided by your network administrator for the library. • Enable HTTPS — when On, the RMI can only be accessed through an HTTPS connection.
For IPv4, you may change the: • DHCP Address — when On, the library will request an IP address from a DHCP server each time the device is booted. The default is On. • Static Address — configures the IP address if DHCP is not enabled. • Subnet Mask — configures the network mask of the library controller if DHCP Address is not On. • Gateway Address — configures the gateway address if DHCP Address is not On.
Figure 80 Configuration: Network Management page You may change the: • SNMP Enabled — When checked, the device can be managed by computers listed in the SNMP Target IP Addresses field. • SNMP Target IP Addresses — the IP addresses for up to three computers running IPv4 SNMP management software and up to three computers running IPv6 SNMP management software.
• Community Name — a string used to match the SNMP management station and device. It must be set to the same name on both the management station and the library. The default community name is public. • SNMP Trap Notification Filter — the types of events for which the device should send SNMP traps. • IPv4 or IPv6 Management Station — IP address of the Command View TL management station. Only one management station can be configured.
Figure 81 Configuration: Password page You may change the: • Password — The password is exactly eight numbers, each from 0 to 9. • Password Time Out — The number of minutes that the current administrator login session will remain logged in without user interaction. Setting the date and time Use the Configuration: Date/Time page to set the date and time. NOTE: The device does not adjust its time to daylight saving time; the time must be adjusted manually.
• UTC Time Zone Offset — Select the time zone for your area. • Enable Daylight Savings Adjustment — Enabling daylight saving time will advance the local time by one hour. This setting does NOT automatically adjust the device time for daylight saving time based on the calendar. You must manually enable this setting when daylight saving time starts in your area and disable it when daylight saving time ends. Setting error log mode The Configuration: Log page can only be accessed by HP Service personnel.
Saving and restoring the device configuration and restoring factory defaults Use the Configuration: Restore defaults page to restore the factory defaults, reset the administrator password to null, or save the device configuration database to a file.

The administrator password grants access to all OCP functions except HP Service.
Figure 102 Mailslot-capable magazine and slot, each marked with a white dot The library will eject the mailslot in the lower left magazine when instructed to open mailslots. After the mailslot is closed, the library will inventory the tapes in the mailslot, but not the rest of the tapes in the magazine, which allows the library to resume operations sooner. On the MSL8096, the upper-right magazine can be configured as a 12–slot mailslot.
Figure 104 Removing the existing tape from the mailslot On the MSL8096, the magazine in the upper right side will be unlocked if it is configured as a mailslot and you choose to open it. To open the upper right magazine, grasp the magazine and pull it straight out until you can access the desired slot. NOTE: The following message may be displayed: Mailslot opening. No button pushes are accepted during this time.

NOTE: The number of drives available for selection in the Status menu depends on the number of drives that have been active in the library. For a library that has only two drives, the menu displays Drive 1 and Drive 2. For a library that has four drives, the menu displays Drive 1, Drive 2, Drive 3 and Drive 4 (even though the status of some may be offline or missing). • Library: displays the status of the library without the drives.
Viewing inventory information (Info > Inventory) Inventory information can be displayed for a magazine or for a drive. • Magazine: The first inventory screen displays the contents of magazine number 1 (lower left). The top section of this screen shows which mailslots are occupied (shaded background) or empty (white background). If the mailslot is enabled, the storage slot count is reduced. The lower section gives more information about each slot.
NOTE: The library's SCSI ID will be the master drive's SCSI ID with a LUN of 1. • Library Mode: The library supports three behavior modes: Random, Sequential, and Automatic. The library automatically detects the required mode from the series of SCSI commands it receives; however, you can also change the mode. Choose the operating mode based on the capabilities of the software controlling the tape cartridges. The library mode can be set independently for each logical library.
When a library is partitioned into logical libraries, each logical library operates as an independent library. Thus, the library only loads tapes from the slots associated with one logical library into the tape drive associated with that logical library; it will not load tapes from slots associated with another logical library. Only the lowest-numbered tape drive in a multi-drive logical library will be used.
Setting and changing the administrator password (Configuration> Set Admin Password) This option allows you to change the administrator password. Access to this feature requires the administrator password or the Service password. Passwords consist of exactly eight characters each between the value of 0 and 9.

On the MSL8048 and MSL8096, the library leaves all magazines on a side unlocked for several seconds. During that time, you can pull out as many magazines on the side as you want. A magazine is locked when it is pushed back into the library. The library will wait about 30 seconds after the last magazine is installed before starting the inventory. Before the inventory starts, you can unlock the magazines on either side. NOTE: Due to the library design, all left or all right magazines will be unlocked.
Powering drives on and off (Support > Power on/off Drives) This option allows the powering up or down of a drive without interrupting power to the rest of the library and the other drives. This is typically used when replacing one drive. Access to this feature requires the administrator password. Cleaning the tape drive (Support > Clean Drive) This option allows you to clean the drives. Access to this feature requires the administrator password.
The library only supports signed firmware image upgrades and downgrades. Once firmware that uses code signing is loaded, the firmware will reject all unsigned images. If you attempt to load an unsigned firmware image, the RMI displays an invalid firmware version error message: If you see this message, download the latest signed firmware image from the MSL website at: http://www.hp.
Force ejecting a drive (Support > Force Drive Eject) This option attempts to force the tape drive to eject the tape and place it into an open slot in the library. Access to this feature requires the administrator password. Before issuing this command, HP recommends that you attempt to eject the tape using the backup software and move command on the operator control panel. While a drive is being force ejected, a window indicating the process is ongoing should appear.
5 Troubleshooting CAUTION: This library is designed to operate when installed in a rack using the included rack rails. The MSL2024 and MSL4048 can also be set on a flat surface when mounted in the optional Rack-to-Tabletop Conversion Kit. Operating the library without one of these kits, such as on a flat surface without the Rack-to-Tabletop Conversion Kit, could result in device errors. Placing any weight on top of the device might also cause errors.
Figure 108 MSL2024 parallel SCSI tape drive default SCSI addresses 1. Tape drives with SCSI address 4 2. Tape drives with SCSI address 5 – MSL4048: For full-height tape drives the default SCSI address is 4. For half-height drives, the default SCSI address for the bottom drive in each full-height drive bay is 4 and the default SCSI address for the top drive is 5 as shown in “MSL4048 parallel SCSI tape drive default SCSI addresses” (page 143).
Figure 110 MSL8048 and MSL8096 parallel SCSI tape drive default SCSI addresses 1. Tape drives with SCSI address 4 Depending on other devices attached to the same parallel SCSI bus and their SCSI IDs, you may need to change the SCSI ID before using the device. Review the manuals for the other devices on the parallel SCSI bus or your operating system to determine which SCSI IDs are currently in use.
pins. The length of the internal parallel SCSI cabling inside the device is 0.5 m (1.6 ft). This length must be included in any calculations of cable length. • – For LVD SCSI, the maximum length with only a single device on the parallel SCSI bus is 25 m (82 ft). – For Ultra 320 or multiple devices on an LVD bus, the maximum combined internal/external length is 12 m (40 ft).
NOTE: The host bus adapter should be SCSI-3 LVDS. A single-ended parallel SCSI host bus adapter severely degrades performance. Also, if any SE devices are on the same parallel SCSI bus, all of the devices on the bus slow down to SE speed, which severely degrades performance. The library is NOT compatible with a standard differential (Diff) or high-voltage differential (HVD) SCSI bus. • Verify that your HBA is supported by the host computer and qualified with the library.
• ◦ Verify that your HBA is supported by the host computer and qualified with the library. For current HBA compatibility information, see the EBS compatibility matrix at http:// www.hp.com/go/ebs. ◦ Verify that your HBA has the latest firmware. If the application software or operating system detects the tape drive, but not the library: ◦ Verify that multiple LUN support is enabled on the HBA. The device uses two Logical Unit Numbers (LUNs) to control the tape drive (LUN 0) and robotic (LUN 1).
If the screen shows Logged Out: • Check that the Fibre speed is set to Automatic (on the RMI) or Auto Detect (on the OCP), or that the correct fibre speed is selected. If you are unsure of the speed of the HBA or switch that the library is connected to, try Automatic (on the RMI) or Auto Detect (on the OCP). • Check that the correct port type, fabric or loop, is selected. Loop requires additional configuration.
