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.
Also, the value specified in CDB byte 2 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 3 to 4 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).
(2) Release object and third party release function
The third party reserve function is not supported by the drive.
If the 3rd Pty bit of CDB byte 1 is "0," the IDD is reserved for the INIT that has
issued this command. The INIT has the reserve right for the IDD.
If the 3rd Pty bit is "1," execution of this command is terminated with the
CHECK CONDITION status (ILLEGAL REQUEST [= 5]/Invalid field in CDB
[= 24-00]).
