HP StoreEver MSL2024, MSL4048, MSL8048, and MSL8096 Tape Libraries User and Service Guide (AK378-96059, December 2012)

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.
Automatic mode: In Automatic mode, the device switches from Sequential mode into Random mode
when it receives certain SCSI commands. Automatic mode is the default setting.
Automatic cleaning
When auto clean is enabled, the tape library automatically loads a cleaning cartridge when a
tape drive needs to be cleaned. The library identifies a tape cartridge as a cleaning cartridge if
it has a barcode label that starts with CLN or after an unlabeled cleaning tape has been loaded
into the tape drive.
The library can use a cleaning cartridge from any slot, even if the slot is reserved. The library keeps
track of the usage count for each of the cleaning cartridges. When multiple cleaning cartridges
are available, the library will first choose an unknown cleaning cartridge so the library can start
tracking the cartridge's usage count. If the library knows the usage count for all of the cleaning
cartridges, the library will choose the one with the highest usage count.
Auto cleaning is disabled by default. You can enable automatic cleaning even if there are no
cleaning cartridges in the device. In this case, the device will display a warning message.
CAUTION: Only enable automatic cleaning in either the backup application or the library, not
both.
Changing the drive configuration (Configuration > Drives)
Parallel SCSI drives: This option allows you to configure the SCSI ID of the drive.
CAUTION: If you change the SCSI ID, you must also cycle power on the host server and
reconfigure the backup software before using the library.
Fibre Channel drives: This option allows you to configure the Fibre Speed, Type, ALPA, and Loop
mode for the drive's Fibre Channel ports. See “Changing the drive configuration” (page 85) for
more information about configuring the Fibre Channel ports.
Access to this feature requires the administrator password.
To change the drive configuration:
1. Highlight the setting you want to change. Press OK to select the value field.
2. Press the Up or Down buttons until the correct value is displayed. Press OK to accept
the value.
3. Press the Up or Down buttons to navigate to <Save>. Press OK to save.
Changing the network configuration (Configuration > Network)
The library can automatically obtain an IP address from a DHCP server when the library is powered
up. The library also supports user-specified fixed addresses through the front panel. This option
allows the operator to set the network settings or allow the library to autoconfigure using the DHCP
server settings.
Access to this feature requires the administrator password.
Barcode reporting format (Configuration > Barcode Reporting)
This option sets the format for displaying the tape bar codes for both the operator control panel
and the host. With this option, you can configure the number of characters to display and the
justification of those numbers to the left or right. Access to this feature requires the administrator
password.
