Report LUNS 5
Implemented per specification.
See Report LUNS (A0h) on page 73 for more information.
Request Sense 5
The DX-Series system sense data size is 24 bytes whereas the ATL P1000
is 21 bytes. The extra 3 bytes are located at the end and are reserved.
All Sense Codes related to mechanical failures have been removed from
the list since they will never occur.
See Request Sense (03h) on page 75 for more information.
Request Volume Element Address 5
The DX-Series system returns a check condition, unsupported command,
whereas the ATL P1000 supports this command.
See Request Volume Element Address (B5h) on page 79 for more
information.
Reserve 5
The DX-Series system only performs Unit Reservations. Element
reservations are validated but are never made nor tracked.
When a reservation is made for itself, the reservation is bound to its’
World Wide Node Name and not the ReservationID value passed in the
Command.
See Reserve (16h) on page 95 for more information.
Rezero Unit 5
Implemented per specification.
See Rezero Unit (01h) on page 99 for more information.
