Library Installation Preparing the Host for Installation
Preparing the Host for Installation
NOTE Ensure that you have a host bus adapter card that is compatible with the library. Install the SCSI host bus adapter card(s) and compatible driver(s). Refer to the host computer user manual and host bus adapter card instructions, and follow these general steps: 1. When the host is powered on, install software and/or driver(s) into the host that are compatible with the library. 2. If the host computer is connected to a network, check with the system administrator before turning off power. 3. Properly power off all peripheral devices connected to the host computer. 4. Power of the host. Use proper procedures to prevent electrostatic discharge (ESD). Use wrist-grounding straps and anti-static mats when removing internal components. Make sure that the host computer has an appropriate number of card expansion slots available for your library model. Ensure the host bus adapter card is supported by your backup software application. For optimum performance, there should be a maximum of one tape drive per bus. HP supports up to two drives per SCSI host bus adapter but recommends only one drive per bus. If compression is used when attaching two drives per bus, keep in mind the combined transfer rate of the drives must not exceed the throughput of the host bus adapter used. Refer to Appendix A and the ANSI SCSI cable specification for more information on SCSI cable length requirements. Check for available SCSI IDs if you are installing the library onto the same SCSI bus as other devices. You might need to change the SCSI ID from the library front panel if you think there will be an ID conflict with other devices. Chapter 1 1-23

SCSI Cable Connections

NOTE Refer to Fibre Channel Cable Connections on page 1-33 if the library is configured with Fibre Channel. This section illustrates a standard SCSI configuration that produces a high level of data storage performance (one SCSI host bus adapter card for each drive in the library with the library controller daisy-chained to the first drive). HP supports up to two drives per SCSI host bus adapter but recommends only one drive per bus. If compression is used when attaching two drives per bus, keep in mind the combined transfer rate of the drives must not exceed the throughput of the host bus adapter used. Connect the library as follows (refer to Figure 1-18 through Figure 1-20): 1. Properly power off all peripheral devices connected to the host computer. 2. Power off the host. If the host is connected to a network, check with the system administrator before turning off power. 3. Connect a 68-pin jumper cable from the top connector of the library controller to the left drive module (drive module 1). CAUTION Use SCSI cables and HVDS differential terminators for high-voltage SCSI interfaces. Use SCSI cables and LVDS differential terminators for low-voltage SCSI interfaces. The label on the library controller indicates high or low voltage. 4. Connect the appropriate 68-pin SCSI terminator to the bottom connector on the librarys controller card. 5. Connect a 68-pin SCSI cable from a host SCSI card to each drive module. Add the appropriate terminators to the remaining SCSI connectors. 6. Connect the remote management card (see Using the Remote Management Card on page 3-9).
The AC power cord is the librarys main AC disconnect device and must be easily accessible at all times. 7. Connect a power cord to each power supply module on all levels. 8. Power on the library by pressing the recessed power (standby) switch, located on the front of the library in the bottom right corner. After the power-up test is complete (after several minutes), you will see the Home Screen on the library's front panel. The Home Screen displays the status of the drives and library. See Front Panel Status Information (Home Screen) on page 2-7. 9. Power on other peripherals, and then the host.

Library Operations Drive and Tape Operations
Look at the product information labels on the back of the library and the labels inside each tape door for more information about drive and slot numbering. The numbering scheme is also illustrated in Front Panel Overview on page 2-3 and Library Back Panel on page 1-24. NOTE The Home and Map front panel screens illustrate the drive, slot, and mailslot numbering schemes. Slot numbers displayed in reverse video indicate those reserved for the mailslot.
Loading a Tape Into a Drive
1. From the Drive and Tape Operations menu, select Load Tape from Drive. 2. Use the [-] or [+] key to select any slot. Only full slots are available for selection. Select [OK]. 3. Use the [-] or [+] key to select the desired drive. You can only select empty drives that match the tape type. 4. Select [Load] to move the tape from a slot to a drive. A confirmation screen indicates that the tape is loaded. NOTE You can also load tapes into drives from remote access. See Using the Remote Management Card on page 3-9.
Unloading a Tape from the Drive
1. From the Drive and Tape Operations menu, select Unload Tape from Drive. 2. Use the [-] or [+] keys to select the drive you want to unload. 3. Select [Unload] to move the tape from the drive to the tapes original location (the location it occupied before being loaded into the drive). If that slot is occupied, you will be asked to select another slot location. 4. The tape automatically rewinds before it is unloaded. A status screen displays the librarys progress as the tape is relocated. 5. From the Drive and Tape Operations menu, select [Menu] to return to the Operations menu. NOTE Tapes can also be unloaded from remote access. See Using the Remote Management Card on page 3-9.

Cleaning a Drive

Use a cleaning cartridge to clean a drive. The drive mechanism should only be cleaned if the clean drive icon displays (see Table 2-1 on page 2-9).
Ensure you use the correct cleaning cartridges for your tape drive. Damage may occur if inappropriate media is used. For more information, refer to the HP Tape Library & Autoloader Drive Manual located at www.hp.com/support/modularlibrary.
1. From the Drive and Tape Operations menu, select Clean Drive. 2. From Choose Cleaning Slot, use the [-] or [+] key to select the slot location of the cleaning tape. Refer to the label inside the library door, the front panel display, or Front Panel Overview on page 2-3 for a list of the slot numbers. Select [OK]. 3. Using the [-] or [+] keys, select the number of the drive to be cleaned. Select [Clean]. When the cleaning process is complete, the cleaning tape will be returned to the original slot location. If the cycle failed, the screen will display the appropriate status information. See Troubleshooting Common Problems on page 4-27 for possible cleaning problems. NOTE Drives can also be cleaned from remote access. See Using the Remote Management Card on page 3-9.

Main Menu -> Administration -> Change Configuration -> Fibre Channel
1. Enter the Fibre Channel menu. 2. Select the level where the Fibre Channel controller you want to configure is located. Use the [-] key to select a lower level in the library. Use the [+] key to select a higher level in the library. Select [OK] if the level is correct.
3. A message displays the following information: Fibre Channel controller type (LVD or HVD SCSI) SCSI bus status Select [MORE]. 4. A message displays information for the CURRENT STATUS, including: Link status Connection type (loop or fabric) AL_PA (Arbitrated Loop Physical Address) for loop connections, or a hex address for fabric connections Select [MORE]. 5. A message displays information for the CURRENT SETTINGS, including the addressing assignment method (hard or soft) and the AL_PA for loop connections. Select [MORE]. 6. A message displays information for the FUTURE SETTINGS. This allows you to input the addressing assignment method and AL_PA that you want to use at a later time, without affecting your current connection. (Changes to the FUTURE SETTINGS will take effect on the next power up or board reset.) TIP For multi-level libraries, settings can be changed simultaneously for each level of the library by changing the FUTURE SETTINGS and then powercycling the library. The default addressing is hard addressing with auto-select enabled. Hard addressing allows you to set and maintain a fixed address, but may result in address conflicts. Soft addressing looks for an unused address on every power cycle, so the address might change. NOTE Since AL_PAs can change with soft addressing, some backup software applications may have difficulty locating the library in this mode. Check the backup software documentation to ensure soft addressing is supported before selecting this mode.
Library Administration Configuring the Library for Fibre Channel If you selected hard addressing for a loop connection, select the AL_PA (fixed address) or choose auto-select. Auto-select is an option under hard addressing that selects an available address and then uses it as a hard address from then on. 7. Press [OK] when complete to save the changes, or select [QUIT] to return to the beginning of the fibre configuration menu. If you select [QUIT], a message will display indicating the old values will be retained. If you select [OK], a message will display indicating that the settings are being stored onto the Fibre Channel controller. If this is successful, a message displays indicating that the new settings will be attempted at the next restart. 8. To immediately apply the new settings, select [RESTART], or select [DONE] to wait until the next power cycle. When the Fibre Channel controller is restarted, or when the library is power-cycled, FUTURE SETTINGS are copied into CURRENT SETTINGS. The Fibre Channel controller always attempts to connect using CURRENT SETTINGS. If you select [RESTART], the Fibre Channel controller is restarted. This should not be attempted if data transfers or library operations are in progress. The [RESTART] operation normally completes within 90 seconds. The display will report the status of the operation when it is complete. NOTE The actual connection achieved depends on the external topology and network. Consequently, CURRENT STATUS may differ from CURRENT SETTINGS.

Host Software and Media Errors
The library depends on several other components to operate correctly. Errors that you believe are caused by the library often are a result of errors on the host, the network, or with the backup software. When troubleshooting the library, begin ruling out these components. Use the following troubleshooting procedures to help determine if an error is caused by the library hardware, host, or backup software. Use the remote management card for troubleshooting media errors (see Using the Remote Management Card on page 3-9).
Verify the library hardware is correctly operating.
Ensure the LED on the front panel is not flashing amber. Flashing amber indicates a hardware error. Check the hard and soft error logs.
Run a Wellness Test from the library front panel.
Check the software configuration. Ensure the SCSI IDs are correct on the backup software application.
Verify the software is supported and correctly configured.
Use a different backup software application (if available) and see if a similar error occurs.
Ensure the host can identify the library and drive.
Look for connection errors with the host and network.
Check all cable connections. Ensure the SCSI bus is properly terminated.
Ensure the SCSI host bus adapter card and the drivers are compatible and correctly installed.
Troubleshooting, Removal, and Replacement Understanding Error States Backup Software Errors While the library product itself is supported by Hewlett-Packard, all software products are supported by individual software vendors. (See Backup Software Support on page B-4.) Your software applications may need to be reconfigured or, in some cases, reinstalled after you have installed additional drives or slots into the library. In addition, some backup software applications may require the purchase of additional add-on components and/or licenses when increasing the number of storage slots or drives. Contact your software application provider for more information or if newly installed storage slots and drives are not recognized by your backup software application.
Troubleshooting, Removal, and Replacement Interpreting Library LEDs
Interpreting Library LEDs
LEDs communicate status and errors as they are occurring. Use the library LEDs to determine the state of the library. All library cards and drive modules contain LEDs. In general, a yellow LED comes on during power up and changes to green when power up is successful. This may take a few minutes on some library cards. The LED bar underneath the front panel display indicates library activity.

During normal operations, device addresses do not change. Fibre Channel addresses can only change when device communications are disrupted. Consequently, system software does not need to spend extra time during normal operations to keep track of device addresses. All Fibre Channel devices are identified using their WWN. The WWN is used by system software to locate devices independent of how they are connected to the system so that the software does not need to be reconfigured every time the system is reconfigured. Also, being able to track devices helps prevent losing or damaging data by accidentally accessing the wrong device in the system. This is a very important requirement for the development of the SAN (Storage Area Network) systems.
Common Problems with Fibre Channel
Fibre Channel accommodates many protocols and physical interfaces, but problems can occur with the following: Physical connections Laser power control systems Error recovery Physical Connections Physical connection problems arise from connecting devices with different types of cables, poor connections, damaged cables, or damaged connectors. ANSI controls the cable specification. The maximum distance between devices depends on the type of cable and desired data transmission speed. As with all electrical media, Fibre Channel copper media can radiate RF interferences and can be affected by external RF noises. Because of the distance limitations and noise problems, copper media is only recommended for use inside a cabinet or rack.
Use the optical cable(s) included with the library to connect the library to the Fibre Channel loop (host, hub, or switch).
Optical interfaces support greater distances. ANSI specifies multiple optical interfaces that use lasers, LEDs, and cable types. Generally, cables that support greater distances are more expensive than cables that support shorter distances. Optical cable considerations include the following: Cable between two nodes must use the same core size. Three core sizes supported by Fibre Channel are 62.5 microns multi-mode up to 175 meters; 50 microns multi-mode up to 500 meters; 9 microns single mode up to 10km (with a long-wave GBIC). (These numbers are based on a 1-Gigabit per second data rate.)
The limitation on mixing core sizes applies only to a cable between two nodes and is only a concern when splicing or connecting optical cables directly together.
