without errors.
Busy
The autoloader returns Busy status when it is processing a command for a
different initiator or when it is in the process of aborting a motion command.

The autoloader returns Reservation Conflict status when it or the cartridge
loader is reserved by a different initiator. See Chapter 20 for more information

autoloader is processing the command.

message system is not enabled.
 A Unit Attention condition is pending for the initiator.
 The autoloader has experienced an unrecoverable hardware error.
