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. 

 

When the "3rd Pty" bit in CDB byte 1 is "0," this command cancels a reserve state 
if it exists in the IDD that has been reserved by a RESERVE command without 
the INIT that issued this command specifying the third party reserve function. 

When the "3rd Pty" bit is "1," the third party release function is specified and this 
command can release a reserve state established in the past by the third party 
reserve function.  When the third party release function is specified, this 
command releases the reserve state only when the INIT that issued this command 
is the same as the INIT that used the RESERVE command in the past to specify 
the third party reserve function which caused the IDD to be reserved for the FC 
device (third party device) specified in the "3rd Pty Dev ID" field in CDB byte 1 
of this command.
