The
RELEASE UNIT
command is received from the Initiator that established the reservation.
Any
RELEASE UNIT
originating requester is ignored and Good Status is returned in response
to the command.
Third Party reservations are not supported.
It is not an error to attempt to release an ID that is not currently reserved
to the requesting Initiator. A reservation cannot be released if the
reservation was made by another Initiator. Other events and conditions
that can cause a reservation to be released are discussed under the
command.
