Checking the Drive Order in Libraries

If your automated library contains more than one drive, the order of the drives in the mcf file must be the same as the order of the drives shown by the automated library's controller. The drive that the library controller identifies as the first drive must be the first drive entry for that library in the mcf file, and so on. This order can be different from the order of the devices as reported in the /var/adm/messages file.

This chapter provides procedures for checking the drive order. The procedure varies depending on whether your automated library has a front panel, whether it has tape or magneto-optical drives, and whether it is direct attached or network attached. Each procedure maps the library drives to SCSI target IDs, and then maps the SCSI target IDs to remote tape devices.
