(cont)
Pre-empt The persistent reservation thus created by the pre-empting initiator is
defined by the
Scope and Type fields of the PERSISTENT RESERVE OUT
command and the corresponding fields of the command’s parameter list.
The registration keys for the pre-empted initiators are removed by the
Pre-empt service action; the reservation key for an initiator that has
performed a
Pre-empt service action with its own Reservation key
specified in the
Service action Reservation key remains unchanged,
although all other specified releasing actions and reservation actions are
performed.
Note that persistent reservations are not superseded by a new persistent
reservation from any initiator except by the execution of a
PERSISTENT
RESERVE OUT
that specifies either the Pre-empt or the Pre-empt and Clear
service actions. New persistent reservations that do not conflict with an
existing persistent reservation execute normally.
