Field Definitions

Logical Unit Number (Byte 01, bits 7-5)
The library does not support Logical Unit Numbers, so this field must be 00h.
PF (Byte 01, bit 4)
The library supports the page format specified by SCSI-2. This value must be 1.
SP (Byte 01, bit 0)
The library supports the Saved Page function. The values for this field are as follows:
•
0 - Configuration values are changed to the values specified by this command. Saved
values are not affected.
•
1 - Configuration values sent to the library by this command are saved in nonvolatile
memory and applied.
Parameter List Length (Byte 04, bits 7-0)
The value of this byte represents the length of the entire parameter list. When the value
of the Parameter List Length is 00h, data is not transferred from the initiator. A value of
00h in this field is not considered an error.
