4.6 Response to T10 Letter Ballot comments on SAM-2 (02-155) [Weber]
Ralph Weber led a discussion of the SAM-2 letter ballot comments resolution
(02-155r0).
The group discussed whether or not to remove CRN from SAM-2, per comment
Compaq 23). Removing the term "pending task" and several other comments were
discussed. Ralph agreed to prepare 02-155r1, reflecting the agreements reached
by the group.
4.6.1 SAM-2 comments (02-152) [Gardner]
Ed Gardner, Ralph Weber, George Penokie and several others discussed Ophidian
comments 1 through 8. Ed agreed to prepare an additional proposal regarding

4.6.2 Diagrams pertaining to HP comments on sam2r23 (02-153) [Haagens]
Due to the late hour, discussion of this topic was deferred to the July
meeting.
4.7 This is not a revision of SAM-3 (02-119) [Weber]
Ralph Weber informed the group that 02-119r0 had been placed on the T10 web
site as an example of the shared sources approach he plans to use to keep
SAM-3 current while SAM-2 completes letter ballot comment resolution and
public review.
4.8 SAM-2 SPC-3 SBC-2 SSC-2 Clearing effects of I_T nexus loss (02-134)
[Elliott]
Rob Elliott reviewed the latest revision of the clearing effects proposal
(02-134r1). The group discussed numerous details of the proposal such as
background tasks, deferred errors, and additional sense codes reported.
Substantive changes were requested, including changes in the diagram that
shows the relationships between the various clearing effects events and the
clearing effects for log pages and mode pages.
Consensus could not be reached on the clearing effects for mode pages. Rob
described the importance of agreeing on some SPC-3 changes for SRP and iSCSI
standardization efforts.
Ralph Weber moved that 02-134r2 (r1 as revised) be recommended for inclusion
in SPC-3 with the exception of all the description concerning mode pages and
that the working group further stipulates that all discussion of topics not
related to SPC-3 and of mode page topics be deferred to a future meeting and
revision of the proposal. Rob Elliott seconded the motion. The motion passed
on a vote of 14:1:6.
5. Command Set Topics
5.1 SCSI Device Memory Export Protocol (00-312) [Barry]
Since no revised 00-312 proposal was presented, the operation code for DEVICE
LOCKS will be removed from SPC-3 and this item will be removed from future
agendas. These actions are in accordance with the motion passed at the March
CAP working group (minutes in 02-101).
5.2 SMC-2 Proposal: Read Element Status Device Identifier (02-104)
[Banther]
Michael Banther presented the latest revision of the proposal to specify the
handling of different length Device Identifiers in the READ ELEMENT STATUS
parameter data (02-104r2). Erich Oetting requested editorial changes and
Michael agreed to prepare r3.
Erich Oetting moved that 02-104r3 (r2 as revised) be recommended for inclusion
in SMC-2. Paul Entzel seconded the motion. In the absence of any objections,
the motion passed unanimously.
5.3 Obsolete Reserve/Release (02-108, 02-141) [Peterson]
George Penokie noted that 02-108r0 is already on the T10 plenary agenda, due
to a motion approved at the last meeting.
Dave Peterson presented a description of how to implement persistent
reservations as a replacement for RESERVE/RELEASE (02-141r0).
The group discussed whether the features described in the proposal should be
made mandatory in SPC-3. It was agreed that, since SPC-3 does not make
RESERVE/RELEASE mandatory, there is no need to make any part of persistent
reservations mandatory in SPC-3, such issues can be dealt with in the
individual command set documents.
The group also discussed making the proposal's content an informative annex in
SPC-3. Although no straw poll was taken, making an annex seemed generally
agreeable.
Dave noted that change requests are anticipated for 02-141 from the EXTENDED
COPY development community and agreed to bring a new revision of the proposal
next meeting.
5.4 SBC-2, SSC-2, SMC-2 & OSD Support For All Registrants Persistent
Reservations (02-130) [Weber]
Ralph Weber described the purpose of the proposal as making the other command
set documents consistent with changes already present in SPC-3, and then
reviewed the content of the proposal. Ralph Weber moved that 02-130r0 be
recommended for inclusion in SBC-2, SSC-2, SMC-2 and OSD. Roger Cummings
seconded the motion. In the absence of any objections, the motion passed
unanimously.
5.5 SPC-3 AERC clarification (02-145) [Elliott]
Rob Elliott presented a proposal to clarify the definition of the AERC bit in
the Standard INQUIRY data (02-145r0).
Rob Elliott moved that 02-145r0 be recommended for inclusion in SPC-3. Bill
Galloway seconded the motion. In the absence of any objections, the motion
passed unanimously.
5.6 SPC-3 Informational exceptions, linked commands, and CONDITION MET
(02-144) [Elliott]
Rob Elliott presented a proposal to make informational exceptions work with
linked commands (02-144r0).
The group discussed the operation linked commands and the operation of
informational exceptions.
Rob Elliott moved that 02-144r0 be recommended for inclusion in SPC-3. George
Penokie seconded the motion. In the absence of any objections, the motion
passed unanimously.
