This command releases the reserve state of an IDD in relation to the INIT that issued this
command.
When a reserve state in relation to the INIT that issues this command, or an IDD does not
exist, this command is terminated normally with a GOOD status.
The INIT that issues this command must notify its own SCSI ID when the SELECTION phase is
executed. When the INIT's ID cannot be specified, this command is terminated with a CHECK
CONDITION status (ILLEGAL REQUEST [=5] / Initiator's SCSI ID not identified [=90-00])
without this command being executed. Also, the value specified in CDB byte 4 to 6 has no
meaning and is disregarded, but it is desirable for X '00' to be specified by the INIT in this byte.
Also, the value specified in CDB byte 7 to 8 reports CHECK CONDITION status "05-24-00"
except for X"00" is specified.
(1)
Release function
This command releases a reserve state if a reserve state exists, and if the INIT which issued
this command has a reserve right for the entire IDD (logical unit). See Reserve Right in
RESERVE command (Section 4.1.11) concerning the definition of "Reserve Right."
(2)
Reserve right and third party reserve function
The third party reserve function is not supported in the FC, so if a value other than "0" is set in
the "3rd Pty Dev ID" field, a CHECK CONDITION status "05-24-00" is reported without this
command being executed.
