Changing the System Configuration
Use the to modify the system configuration.
System configuration changes are only applied after the Apply Selections or the
Submit button is selected. After making the selection, a warning page informs you of
the impact of the proposed change. In some cases a pop-up screen asks you to
confirm the change. Many changes also require the device to reboot. You may need to
click Refresh to see the changes.
To enable logical libraries, select the number of logical libraries in the Logical Libraries
pane and click Apply in that pane. For more information about logical libraries, see
“Logical libraries.”
The following settings affect all of the logical libraries:
!
Mailslot Configuration — configures the mailslot in the lower left magazine as a
mailslot or storage slots. The 2U mailslot has one slot; the 4U 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.
!
Auto Clean Enabled — When auto clean is enabled, the device automatically loads
a cleaning cartridge when a tape drive needs to be cleaned. The Tape Library can
load a cleaning cartridge from any logical library to any tape drive. The device
identifies a tape cartridge as a cleaning cartridge if it has a bar code label that
starts with CLN or after an unlabeled cleaning tape has been loaded into the tape
drive. The device can use a cleaning cartridge from any slot, even if the slot is not
active. The device keeps track of the usage count for each of the cleaning
cartridges. When multiple cleaning cartridges are available, the device will first
choose an unknown cleaning cartridge so the device can start tracking the
cartridge's usage count. If the device knows the usage count for all of the cleaning
cartridges, the device 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.
!
Barcode Label Length Reported to Host — the number of bar code characters
reported to the host application. This option provides interchange compatibility with
libraries with more limited bar code reading capabilities. The default is 8.
!
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
CAUTION: Only enable automatic cleaning in either the backup application or the device, not
both.
