Address All Drive Slots (Recommended)
All drives, including empty drive slots, are assigned a
sequential SCSI element address which is always reported to attached hosts.
In this mode, the library does not need to be restarted for newly installed
drives to become usable by attached hosts, and drive SCSI element addresses
never change. Also, empty drive slots can be assigned to a partition.
You should select this setting if using STA. Otherwise, media validation
drives will not show within STA.
Address Only Installed Drives
Only installed drives are assigned a sequential SCSI element
address. Empty drive slots are not assigned a SCSI element address and are
not reported to attached hosts. In this mode, the library must be restarted
before newly installed drives are usable by attached hosts, and drive SCSI
element addresses may change. Also, only installed drives can be assigned to
a partition.
You must select this setting if using ACSLS.
