Logical Mode
During typical day-to-day library operation, the XLS is in logical mode. In logical mode,
one or more software applications control the library and you interact with X-Link from a
logical library perspective. When you interact with the XLS in logical mode:
• You can view and control only those resources (cartridge slots, tape drives, and
I/O ports) that have been assigned to a particular logical library.
• You cannot view or control resources assigned to any other logical library.
• You specify SCSI element addresses for cartridge slots, I/O port slots, and tape
drives.
• The logical libraries may be online or offline.
