ξReserve right and the third party reserve function

Remark

In order to clarify the jurisdiction related to reserve and release, the term "Reserve Right" is used in this manual.

INIT

#A

INIT

#B

SCSI Bus

TARG

#0

TARG/INIT

#1

1.If INIT #A issues a RESERVE command which does not specify the third party reserve function to TARG #0, TARG #0 enters the reserved state from INIT #A and INIT #A has the reserve right with respect to TARG #0. In this case,

ξINIT #A has an exclusive monopoly over TARG #0.

ξAny commands issued to TARG #0 by any other SCSI device (INIT #B, TARG/INIT #1) are rejected with a RESERVATION CONFLICT status, with the exception of an INQUIRY, REQUEST SENSE or RELEASE command. The RELEASE command is terminated normally, but TARG #0's reserve state is not influenced by it.

2.If INIT #A issues a RESERVE command which specifies the third party reserve function ("3rd Pty Dev ID" = TARG/INIT#1), TARG #0 becomes reserved from TARG/INIT #1, but INIT #A has the reserve right. In this case,

ξTARG/INIT #1 has an exclusive monopoly of TARG #0. However, if TARG/INIT#1 issues a RESERVE command, that command is rejected with a RESERVATION CONFLICT status. Also, a RELEASE command is terminated normally, but it has no influence on the TARG #0 reserve right.

ξINIT #A can issue INQUIRY, REQUEST SENSE, RELEASE and RESERVE commands to TARG #0, but other commands are rejected with a RESERVATION CONFLICT status. A RELEASE or RELEASE EXTENDED command issued by INIT #A releases TARG #0's reserved state. Also, a RESERVE or RESERVE EXTENDED command changes the reserve state of TARG #0.

ξCommands issued by INIT #B to TARG #0 are rejected with a RESERVATION CONFLICT status, except the INQUIRY, REQUEST SENSE and RELEASE commands. A RELEASE command is terminated normally, but it has no influence on the TARG #0 reserve right.
