The following document is posted for review.  It is on the agenda for the
Working Group in Colorado.


The current revision of SPC-2 requires that an initiator with a previously
established reservation key must know the key value before it can perform a
Register service action.  There are some multi-initiator environments where
this is unnecessary and costly, in terms of delay and complexity.  This
proposal creates a new Persistent Reserve Out service action that allows an
initiator to register without knowing the existing key value.
