SEPTEMBER 2005 MAGNUM 1X7 LTO AUTOLOADER

24-1

TEST UNIT READY (00h)

24.1 ABOUT THIS COMMAND

The TEST UNIT READY command allows the initiator to determine if the

autoloader is ready to accept all other valid commands, including motion

commands. This is not a request for a autoloader self-test, which occurs at

power-on. If the autoloader is ready to accept any valid command without

returning Check Condition, Reservation Conflict, or Busy status, this

command returns Good status.

Note: The autoloader does not check to see if a different initiator has any

elements reserved. If an element is reserved by a different initiator, the

autoloader returns Reservation Conflict status for the next command after

the TEST UNIT READY command.

24.2 COMMAND STATUS

The autoloader returns a status byte after processing the TEST UNIT READY

command. This section describes when each type of status byte might be

returned.

Good

The autoloader returns Good status when it is able to process the command

without errors.
