Mark Evans moved to recommend that T10 remove asynchronous event reporting
|from SAM-3. George Penokie seconded the motion. In the absence of objections,
the motion passed unanimously.

4.2    Proposal for new arguments for Data-In Delivered and Data-Out Receive
(02-366r0) [Evans]

Mark Evans presented a proposal to add response values to the Data-In
Delivered and Data-Out Received function prototypes in SAM-3 (02-366r0).

inclusion in SAM-3. Ralph Weber seconded the motion. In the absence of any
objections, the motion passed unanimously.

4.3    Review of I_T Nexus Lost Incorporation in SAM-3 r03 [Weber]

Ralph Weber led an editing review of the new Clause 6 (SCSI events and event
notification model) from SAM-3 r03. He noted that the proposal defining the
new clause was edited substantially during incorporation and asked that the
group provide feedback on the resulting new clause

The group requested several changes and Ralph agreed to incorporate the
changes in SAM-3 r04.

4.4    SAM-3 Data-In Size and Sense Data Size for Execute Command (02-404r1)
[Elliott]

Rob Elliott presented a proposal to add sense data and data-in size parameters

traditional SCSI concepts.

Rob agreed prepare a revised proposal for consideration at the next meeting.

4.5    SAM-3 SPC-3 Maximum and first burst size and protocol services (02-403r1)
[Elliott]

Rob Elliott presented a proposal apply first burst size and maximum burst size
to SAM-3 data transfer function prototypes (02-403r0). Concerns were raised

proposal.

Rob agreed to prepare a revised proposal for consideration at the next
meeting.

4.9    SAM-3 Hard reset and multiple port devices (02-473r1) [Elliott]

meeting.

5.2    WWNs for WLUNs (02-254r4) [Penokie]

George Penokie presented a proposal to require logical units, including
well-known logical units, to have a name (02-254r4). The group expressed
concerns about the details of proposed logical unit name definition in SAM-3.
Details of the Association field requirements for the Device Identification
VPD page were also questioned.

George agreed to prepare a new revision reflecting the group's concerns.

George Penokie moved that 02-254r5 (r1 as revised) be approved for inclusion

meeting.

5.4    Allowing TUR through Persistent Reservation (02-304r1) [Penokie]
{previously passed at CAP}

In September, CAP unanimously voted that this proposal be recommended for
inclusion in SPC-3 with the T10 motion deferred to the November T10 meeting.

Emily Hill reported that no issues had been discovered with the proposal

5.5    Media Serial Number (02-485r0) [Hill]

Emily Hill presented a draft proposal to define a new 12-byte command to
return media serial number. The group advised Emily regarding details of how

usage of well known logical units. Other changes were requested and Rob agreed
to prepare a new revision.

Rob Elliott moved 02-394r3 (r2 as revised) be recommended for inclusion in
SPC-3. George Penokie seconded the motion. In the absence of any objections,
the motion passed unanimously.

5.7    SPC-3: Target Mode Pages WLUN (02-460r0) [Penokie]

George Penokie presented a proposal to add a well known logical unit to access
mode pages (02-460r0). Concerns were raised about how mode pages for other
ports could be affected by the proposed well known logical unit.

George agreed to revise the proposal for consideration at the next meeting.

5.8    SPC-3 Add NAA=2 format to VPD 83 (02-454r0) [Coomes]

Jim Coomes presented proposal to add Fibre Channel NAA format 2 to the Device
Identification VPD page (02-454r0). Concerns were raised about the presence of
vendor-specific bits before the OUI, however the group agreed that the
proposal should not be changed.

Jim Coomes moved that 02-454r0 be recommended for inclusion in SPC-3 with
instructions to the editor that the NAA table be modified to reserve all
unused code values. Dave Peterson seconded the motion. The motion passed on a
vote of 17:0:1.

5.9    More on Persistent Reservations (02-483r0) [Cummings]

Roger Cummings presented two issues relating to using Persistent Reservations
as a replacement for Reserve/Release (02-483r0). The group suggested
improvements to the ideas Roger presented.

Roger agreed to prepare a detailed proposal for consideration at the next
meeting.


6.     SCSI Protocol Topics

6.1    Response to FCP-2 negatives at INCITS [Peterson]

John Lohmeyer reported a concern with how PRLI effects have changed in the
revised FCP-2. He noted that the concerned party was considering a request for
a T10 letter ballot on the revised FCP-2. The group agreed that the review
offered by a public review would be sufficient.

Dave Peterson presented the resolutions for FCP-2 to all the HP INCITS
negative comments (02-440r0). He noted that 02-440r0 enumerates the changes
made in FCP-2 to resolve the HP issues. George Penokie noted that resolving
the HP issues also resolves the issues raised by IBM in an INCITS negative
comment.

Dave stated that FCP-2 r08 has been prepared incorporating the changes
described in 02-440r0.

Dave turned to an FC-FS letter ballot comment that requests removing text
concerning ABTS in FCP-2. He recommended that addressing the matter be
deferred to FCP-3. Dave noted that the FC-FS issue was not mentioned in any of
the INCITS negative votes.

Dave raised concerns about the phrase `zero modulo 4' and recommended changing
the phrase to wording be changed to something more people will understand. The
group asked Dave to delay making the change until FCP-3, instead of FCP-2.

Dave noted that a second document (02-267r2) describes additional changes
agreed by the FCP-2 working group in September and already incorporated in
FCP-2 r08.

Dave Peterson moved that the group recommend 02-440r0 as resolving the INCITS
negative comments, recommend 02-276r2 as describing additional approved FCP-2
changes, affirm that the changes made in FCP-2 are substantive, and recommend
that FCP-2 r08 be returned to INCITS for a second public review. Cris Simpson
seconded the motion. In the absence of any objections, the motion passed
unanimously.

6.2    FCP-2: Issues To Resolve (02-267r2) [Peterson]

This topic was discussed under item 6.1.

6.3    Response to HP INCITS No Vote on FCP-2 (02-440r0) [Peterson]

This topic was discussed under item 6.1.

8.     New Business

No new business was brought before the meeting.


9.     Review of Documents

9.1    SRP-2 Review [Simpson]
