4.     Physical Topics

No physical topics were presented to the group.

5.     Architecture Model and Protocol Topics

5.1    SAM-2 Review [Weber]

Ralph Weber reviewed the content of new SAM-2 clauses concerning devices with
multiple service delivery ports.  The group agreed on several corrections and
improvements to the new text.  Ralph agreed to include the results of the
discussion in SAM-2 revision 11, along with other T10 approved changes to
SAM-2.  Ralph noted that SAM-2 revision 11 would be available for the next
committee mailing.

5.2    SAM-2 changes for queuing (99-207r0) [Weber]

The group could not agree on the handling of untagged tasks in the presence of
a contingent allegiance condition and Ralph withdrew the proposal.

5.3    TTD Proposal (99-195) [Renner]

John Lohmeyer reported that no proposal has been received regarding TTD.  The
group agreed to defer consideration of this topic to the September meeting.

6.     Command Set Topics

6.1    Device locks command (98-225) [Houlder]

Gerry Houlder reported that no new information is available on this topic at
this time and requested that discussion of this topic be deferred to the
September meeting.

6.2    Extended Copy command (99-163r1) [Weber]

Ralph Weber explained that the 99-163r1 proposal contained three TBD sites in
need of references to Fibre Channel standards.  He then reviewed the text to
replace the three TBD instances.  Corrections were recommended and accepted
for the wording of the replacement text.  Tom Coughlan noted that the contents
of SPC-2 table 6 needs to be specified in the 99-163r1 proposal and Ralph
agreed.

Ralph explained that expeditious inclusion of EXTENDED COPY in SPC-2 is
critical because a statement needs to be made to the product development
community that this definition of EXTENDED COPY is support by the standards
committee.  Development is in progress based on an older, incompatible version
of the EXTENDED COPY proposal and T10 needs to show definitively that the
older definition will not be approved for inclusion in SPC-2.  Approving the
new definition should send the needed message.


Ralph noted that 99-163r1 represented the consensus of the May working group
and that no additional comments have been received in the intervening two
months.  The only changes required are those the group has already discussed.

Tom Coughlan noted that the interactions with persistent reservations are not
completely defined and requested specific wording regarding the actions of the
copy manager upon receipt of an abort task set request.  Ralph asked that
those issues be addressed in a separate proposal against SPC-2.

Ralph asked the working group to approve inclusion in SPC-2 of 99-163r2, which
will be 99-163r1 modified by replacing the three TBDs with the text shown and
by adding EXTENDED COPY to table 6 with the same properties as the COPY
command.  In the absence of any objections, the group recommended that
99-163r2 (r1 as revised) be approved by T10 for inclusion in SPC-2.

6.3    Application Client Log Page proposal (99-180) [Houlder]

Gerry Houlder presented the revised proposal for a log page to contain
standard formatted, non-specific application client data.  He was asked to
reserve a block of parameter codes for future standardization.  He agreed to
prepare a r1 containing the changes agreed to by the group.  In the absence of
any objections, the group unanimously recommended that 99-180r1 (r0 as
revised) be approved by T10 for inclusion in SPC-2.

6.4    Persistent Reservation: Register and Ignore Existing Key (99-199r0)
[Coughlan]

Tom Coughlan presented a proposal to add a PERSISTENT RESERVE OUT action code
that registers a key but does not require the initiator to provide the
previous registered key as a check when doing so.  Several editorial
corrections were noted.  In the absence of any objections, the group
unanimously recommended 99-199r0 for inclusion in SPC-2 with the agreed
editorial corrections to be made by the technical editor during incorporation.

6.5    Logical Unit Self Test (99-179r2) [Evans]

Mark Evans presented a proposal for enhancing the capabilities of the
self-test features of the SEND DIAGNOSTIC command.  The group noted several
editorial corrections.  Mark agreed to bring a revised proposal to the
September working group meeting.

6.6    Remove Untagged Command Support Requirement from SAM-2 (99-207r0)
[Weber]

This item was covered as item 5.2.

6.7    REPORT LUNS and small allocation lengths (99-197r0) [Elliott]

Rob Elliott described a problem where the REPORT LUNS command places
restrictions on the allocation length field that differ from the restrictions
used by any other command.  The group requested an editorial change in the
proposal and Rob agreed to the change.  In the absence of any objections, the
group unanimously recommended 99-197r0 for inclusion in SPC-2 with the agreed
editorial correction to be made by the technical editor during incorporation.

6.8    SCSI networking [Parker]

Keith Parker reported the history of the inaction on the SSS project, the
project that T10 requested be closed at the May plenary meeting due to lack of
progress reports or other signs of activity.  He described the virtues of the
SSS draft standard.  Keith was assured that the operation codes set aside for
SSS would not be reassigned anytime soon.  He stated that work will proceed
with prototyping the command set and addressing concerns with the current SSS
document.  The group agreed to support continued work on SSS drafts as a
committee document.  The group felt that acting to reinstate the project would
be premature until such time as members could sense some assurance that a
completed draft standard (or technical report) was likely.

6.9    MRIE behavior with TEST bit asserted (99-208) [Elliott]

Rob Elliott requested that action on this item be deferred to the September
meeting.

6.10   New ASC/ASCQs (99-210r0) [Williams]

Jeff Williams presented a proposal for new ASC/ASCQ codes for CRC and other
parity errors.  The group asked for the addition of codes for a couple of
cases not considered in the proposal and Jeff agreed to produce a r1 with

those additions.  In the absence of any objections, the group unanimously
recommended 99-210r1 (r0 as revised) for inclusion in SPC-2.

6.11   Preempting exclusive type persistent reservations, allowed or not
allowed? [Penokie]

The group discussed a problem with the table describing the preempt service
actions.  Tom Coughlan agreed to prepare a proposal (99-219) showing the
changes agreed by the group for consideration at the T10 plenary.

6.12   ASC 5Dh for SBC devices [Elliott]

Rob Elliott sought a way to incorporate the ASCQs for ASC 5Dh (informational
exceptions or failure prediction) in SBC.  Gene Milligan stated that the
objective could be achieved by creating a proposal to add the codes to SPC-2,
which will have the effect of adding the codes for SBC devices.  Ralph Weber
was not sanguine about adding nearly 80 codes to the ASC/ASCQ table, but
relented.

Rob created 99-217r0 containing a list of the new ASCQs to be defined in
SPC-2.  In the absence of any objections, the group recommended 99-217r0 for
inclusion in SPC-2.

7.     New Business

7.1    Domain Validation TR Project Proposal (99-214r0) [Lamers]

Larry Lamers presented a project proposal for an NCITS Technical Report on the
subject of Domain Validation.  The group noted several corrections.  Larry
agreed to prepare r1 containing the corrections agreed by the working group.
In the absence of any objections, the working group recommended that 99-214r1
(r0 as modified) be processed by T10 as a project proposal for a technical
report.

7.2    T10.org

John Lohmeyer reported that the T10 web site has been moved from
www.symbios.com/t10 to www.t10.org.  He noted that the new ftp site,
ftp.t10.org, requires an e-mail address as a password.  People who receive
`login incorrect' error messages should make sure their web browsers are
configured to send their email address as the anonymous ftp password.  John
also described the spam filtering mechanism recently placed on the T10
reflector.  John said that the T10 reflector would be moved to t10.org the
next week.

8.     Meeting Schedule

meeting will be at the Hilton Waterfront Hotel (714-960-7873) in Huntington
Beach, CA hosted by QLogic.

9.     Adjournment
