*The HP StorageWorks MSL2024 tape library uses a single SCSI ID and dual LUNs to control the tape drive (LUN 0) and library robotic (LUN 1). The library requires an HBA that supports LUN scanning. If it is
not enabled, your host system scan beyond LUN 0 fails to discover the library. It just sees the tape drive.
*Depending on whether you have an LSI or Adaptec Ultra 320, you will have to go in to the SCSI BIOS and enable LUN in the SCSI configuration utility.
*Ensure the library is properly terminated. If the library is the only SCSI device, other than the SCSI host adapter on the selected SCSI bus, it must be terminated. Likewise, if the library is physically the last SCSI device on the SCSI bus, it must be terminated. Only the devices physically located at the beginning and end of the SCSI bus should be terminated.
* Verify the connection between the library and the host by Installing the HP Library & Tape Tools diagnostic/installation check utility available at
www.hp.com/support/TapeTools. Install this utility onto the host server. This utility verifies that the library is connected and communicating with the host server. It also verifies that the library is
functioning and provides diagnostic information. Run the HP Library & Tape Tools Installation.
* Confirm the host server├в s operating system recognized the library in Microsoft
In Windows XP, Windows├В┬о Server 2003 or in Windows 2000 by going to:
Settings > Control Panel > System > Hardware > Device Manager > Tape Drive and/or Media
Changer.
Setting the master drive:
-------------------------
1. From the Home screen, press Previous or Next until the screen displays Configuration. Press Enter to select.
2. Press Previous or Next until the screen displays Set Master Drive. Press Enter to select.
3. Enter the Administrative password if prompted.
4. Press Previous or Next until the screen displays either Master Drive, Drive 1 or Master Drive, Drive 2.
5. Press Enter to select the displayed configuration. The screen displays either Drive 1 Set to Master, or Drive 2 Set to Master.
Library Operation Mode: Random
-------------------------------
Random mode is used when there is a full featured or a robotics aware backup application in use. This is the most common mode of operation. In Random mode, the library does not automatically load tapes into the drive; it waits for commands from the software. Your backup software must support robotics, which may require the additional installation of a library module.
To set a library mode, do the following:
1. From the Home screen, press Previous or Next until the screen displays Configuration. Press Enter to
select.
2. Press Previous or Next until the screen displays Library Behavior. Press Enter to select.
3. Enter the Administrative password if prompted.
4. Press Previous or Next until the screen displays Set Library Mode. The second line on the display reads
Automatic, Sequential, or Random. Press Enter.
5. Press Previous or Next to scroll through the screens for Automatic, Sequential, or Random. Press Enter
to select the library mode.
6. Press Previous or Next until the screen displays either Autoload Mode Disabled or Autoload Mode
Enabled. To change the library mode, press Enter.
7. The screen displays either Disable Autoload Mode or Enable Autoload Mode. Press Previous or Next
to toggle between enabled and disabled screens. Press Enter to select library mode.
8. Press Previous or Next until the screen displays either Loop Mode Disabled or Loop Mode Enabled. To
change loop mode, press Enter. The screen displays either Enable Loop Mode or Disable Loop Mode.
Press Enter to select the loop mode.
Hope this helps!
