RE: iSCSI:reservations

Elliott,

Thanks. Unfortunately I have to send our text before the Friday call time (too close to the IETF deadline) so we will assume
some outcome and adjust for the T10 decision later.

T10 is going to discuss this issue on a Friday conference call for both
iSCSI and SRP (InfiniBand) and should have a recommendation for you
then.  Anyone interested is welcome to join the discussion.

Here is the meeting announcement posted to the T10 mailing list:

* From the T10 Reflector (t10@t10.org), posted by:
* "Simpson, Cris" <cris.simpson@intel.com>
*
The SRP WG will discuss reservation issues for at least the first hour
of
this Friday's conference call. As the issues are of wide concern to the
SCSI community, all interested parties are invited to participate.
