4-3.20 RECEIVE DIAGNOSTIC RESULTS (FACTORY MODE) command 1Ch
The RECEIVE DIAGNOSTIC RESULTS (FACTORY MODE) command requests that result data,
generated for a previous SEND DIAGNOSTIC command, be sent to the initiator.
The RECEIVE DIAGNOSTIC RESULTS command as described in
this section requires that the tape drive be set in FACTORY MODE.
The results of the SEND DIAGNOSTIC command may be lost to
another initiator on the SCSI bus if the LUN under test has not been
reserved to this initiator, or if the RECEIVE DIAGNOSTIC RESULTS
command is not linked after the SEND DIAGNOSTIC command.

Operation code.
The Allocation Length specifies the maximum number of bytes that the initiator has
allocated for returned RECEIVE DIAGNOSTIC data. An allocation length of 0
indicates that no RECEIVE DIAGNOSTIC data is transferred. This condition is not
considered an error. The target terminates the DATA IN phase when all allocation
length bytes have been transferred or when all available RECEIVE DIAGNOSTIC
data has been transferred to the initiator, whichever is less. (Refer to Table 4-76 for
parameter list length values for RECEIVE DIAGNOSTIC RESULTS in FACTORY
MODE).
