Reserve Extended (56) - Fujitsu MAA3182FC Series Manual

INIT
#A
TARG
#0
1. If INIT #A issues a RESERVE command 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,
•
INIT #A has an exclusive monopoly over TARG #0.
•
Any commands issued to TARG #0 by any other FC device (INIT #B) 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.
