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

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.
CAUTION: Since the mailslot is located where the lowest numbered storage slot would be,
enabling and disabling the mailslot will re-number all of the other storage slots. After enabling
or disabling the mailslot, update the backup software inventory. You might also need to
re-configure the backup software to adjust the number of storage slots and presence of the
mailslot.
• Mailslot Configuration (MSL8096) — configures the mailslot in the lower-left magazine and
upper-right magazine as mailslots or storage slots. Enabling a mailslot will reduce the number
of storage slots. The default is 0 mailslots enabled.
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.
From the MSL8096 RMI, you can enable either or both of the mailslots by selecting the number
of mailslot slots in the Mailslot Configuration drop down list.
◦ 0 disables both mailslots.
◦ 3 enables the lower-left mailslot only.
◦ 12 enables the upper-right mailslot only.
◦ 15 enables both mailslots.
CAUTION: Since the lower-left mailslot is located where the lowest numbered storage slots
would be, enabling and disabling it will re-number all of the storage slots. On the MSL8096,
enabling or disabling the lower-left magazine also affects the numbering of the slots in the
upper-right mailslot. After enabling or disabling the lower left mailslot, update the backup
software inventory. You might also need to re-configure the backup software to adjust the
number of storage slots and presence of 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.
CAUTION: Only enable automatic cleaning in either the backup application or the device,
not both.
• 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 maximum length is 15 and the default is 8.
