To further determine how you want tapes loaded into the tape drive while in Sequential mode,
you can set the Loop and Autoload options.
When Autoload mode is set, the device automatically loads the cartridge from the
lowest-numbered full slot into the tape drive. It then follows standard sequential operation.
After configuring Autoload mode, you must do one of the following for Autoload mode to
Power cycle the device from the front panel.
Reboot the device from the RMI Support > Reboot screen.
Move the lowest-numbered cartridge to the drive before starting the backup application.
If the mailslot is enabled, the lowest cartridge location will be in the mailslot.
When Loop mode is on, the original first cartridge in the sequence is reloaded after the
device has cycled through all available cartridges. If Loop mode is off and the last cartridge
has been unloaded, the device stops loading cartridges until you load another manually.
overwrite data on previously written cartridges.
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
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.
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.
Changing the drive configuration (Configuration > Drives)
Parallel SCSI drives: This option allows you to configure the SCSI ID of the drive.
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
for more information about configuring the Fibre Channel ports.
Use caution when choosing Loop mode because it makes it possible to
Only enable automatic cleaning in either the backup application or the library, not
If you change the SCSI ID, you must also cycle power on the host server and
