SEND DIAGNOSTIC (1Dh)
22.1 ABOUT THIS COMMAND
The SEND DIAGNOSTIC command causes the autoloader to perform its
diagnostic self-test. If a test is successful, the autoloader returns Good status;
otherwise, it returns Check Condition status. When this command is followed
by a RECEIVE DIAGNOSTIC RESULTS (1Ch) command or a REQUEST
SENSE (03h) command, the results of the self-test are reported to the initiator.
Notes:
 To ensure that the diagnostic data returned is valid, the SEND DIAGNOSTIC
command must be immediately followed by the RECEIVE DIAGNOSTIC
RESULTS command.
 To ensure that the results of the diagnostic test are not destroyed by a command
sent by another initiator, the autoloader should be reserved for the initiator’s
exclusive use.
 The initiator must support the disconnect option if you plan to use the SEND
DIAGNOSTIC command because the autoloader will disconnect from the
initiator while the command is executing.
