Identity
!
Random — the device will not automatically load and unload tapes. Instead, it
will wait for commands from the backup software or the OCP to load and
unload tapes.
!
Sequential — the device will automatically unload the tape in the drive when
the host software sends an unload command to the drive and then
automatically load the tape from the next highest sequentially numbered full
slot.
!
Loop — in Loop mode, the Library will load the tape from the lowest numbered
full slot after the tape from the highest numbered full slot is unloaded. If Loop is
not listed, the Library will stop automatically loading and unloading tapes after
the tape from the last full slot is unloaded.
!
Autoload — the device will automatically load the tape from the lowest
numbered full slot on power up.
!
WWide Node Name — a world wide unique identifier that the Library reports over
SCSI and may be used by operating systems or software applications to identify
and track the Library.
Viewing Static Drive Information
The Identity: Drive page (Fibre Channel) provides detailed information about the tape
drive. You will only see the fields that apply to the interface type of the drives installed
in this Library.
Caution. Since loop mode will endlessly cycle through the tapes, it is possible to overwrite old
data. Make sure that there are enough tapes in the Library or that the tapes are regularly
rotated in and out to ensure that data you want to save is not overwritten.
