Inquiry Standard Data: Valid LUN (Logical Unit Number)
The following tape
library-specific parameters apply
to this request:
- CmdDt: B'0'
- EVPD (Enable Vital Product Data): B'0'
- Page Code: X'00'
- Allocation Length: X'38' (56) bytes available
Table 1 shows the standard inquiry data that is returned
(character fields are in ASCII) for a logical unit number (LUN) that is configured as a SCSI Medium
Changer. For more detail, go to the section about default SCSI ID and Loop ID (AL_PA) assignments
for the tape library.
