Report LUNs Command Definitions:
Select Report This field specifies the type of logical unit addresses that shall be reported.
• 00h = LUN addresses reported shall be limited to the following
addressing:
• LUN addressing method.
• Peripheral device addressing method.
• Flat space addressing method.
• 02h = All LUNS accessible to the initiator for this port are accessible.
IBM Bridged Drive Note: A Select Report option of 2 is not supported by
an IBM Bridged Tape Drive. The SCSI Report LUNs command with a Select
Report option of 2 will end in Check Condition Status, when the Bridged
Tape Drive is an IBM tape drive. The additional sense data will indicate
there is an invalid field in the command descriptor block (CDB).
Allocation Length
This field specifies the number of bytes that the initiator has allocated for
data to be returned from the Report LUNs command.
HP Bridged Drive Note: The Allocation must be at least 16 bytes. If it is
less, a check condition is returned with the sense key set to illegal request
and the additional sense data set to invalid field in the command
descriptor block (CDB).
