Note:
See Section 1.6, "Sense Data Hold State" concerning details of the sense data hold state and
see Section 5.1, "Sense Data" concerning the format of sense data transferred by this command
from the IDD to the INIT, and its contents.
If this command is issued while the IDD is holding the UNIT ATTENTION condition, if the IDD
is not in the sense data hold state at that point, sense data indicating the UNIT ATTENTION
condition are sent to the INIT by this command and the UNIT ATTENTION condition is cleared.
For details, see Section 1.5, "UNIT ATTENTION Condition."
If this command is issued when valid sense data are not being held, the IDD sends the sense key
"NO SENSE[=0]" with sense data showing the message "No additional sense information [=00-
00]" to the INIT.
This command is terminated abnormally with a CHECK CONDITION status reported only when
the conditions shown below are detected. In this case, new sense data are generated and the sense
data which had been held up to that point are lost.
x An error in a specification other than the LUN field of the CDB
x Sense data cannot be sent due to a hardware error in the IDD
x An unrecoverable error is detected on the SCSI bus.
x A state appropriate to an overlapping command exception condition (see Section 1.7.1).
In cases other than the above, the sense data currently being held, or, when there are no sense data
being held, the sense data which indicate the state if an error occurred during execution of this
command, are sent to the INIT and it is terminated with a GOOD status. However, if an error
which has been recovered from by retry processing is detected during execution of this command,
and if the mode which reports "RECOVERED ERROR" is specified, this command is terminated
with a CHECK CONDITION status after sense data are sent to the INIT and sense data
(RECOVERED ERROR [=1]) which indicate the contents of that error are newly generated.
