inquiry of the tape drives.
Inquiry Sequence:
1. To check installed tape devices, type the lsdev -Cc tape command. From the
listing of devices, remember the ones you are going to test. In the following
example, fibre devices rmt0 and rmt1 are available, which indicates they can

The SCSI devices rmt2 and rmt3 are available and at port addresses (2,0) and (1,0)
respectively. These are SCSI addresses 2 and 1.
