Results of Meeting
1. Opening Remarks
John Lohmeyer, the X3T10 Chair, called the meeting to order at 1:00
p.m., Thursday January 12, 1995. He thanked Steve Finch of Silicon
Systems for arranging and hosting the meeting.
John informed the committee that he would be attending the meeting as
a non-voting chairperson representing NCR Microelectronics Products
Division and not AT&T. His corporate affiliation is changing because
NCR Microelectronics is being purchased by Hyundai.
John said that X3 Subgroup Membership forms and the X3T10 Mailing
Subscription form were available on the document table. He said that
people should use the X3 forms to insure the X3 Secretariat has the
latest membership information. These forms should be mailed directly
to the X3 Secretariat.
As is customary, the people attending introduced themselves and a
copy of the attendance list was circulated. Copies of the draft
agenda and general information on X3T10 were made available to those
attending.
2. Approval of Agenda
The draft agenda was approved with the following changes:
10.2 Immediate Commands (94-244r1) [Lappin]
10.3 Exception Handling Selection Mode Page (94-190r4) [Penokie]
10.4 Conflict between READ LONG and Read/Write Error Recovery
Page [Milligan]
10.5 ATA Systems Issues Study Group [Penman]
The agenda was approved with the above additions.
3. Attendance and Membership
The membership requirements were reviewed. X3 rules permit one vote
per organization. An individual from a new organization must attend
two out of three consecutive plenary meetings. He/she may apply for
voting membership the second meeting via a letter to the Chair of
X3T10. The individual may vote at the second plenary meeting.
Working group meetings do not count toward attendance requirements.
Organizations must also pay the X3 Service Fee ($300) to maintain
membership. The International Program fee ($300) is billed
separately directly from ANSI.
The Chair said he had sent letters to 11 people from 3 organizations
informing them that their membership was in jeopardy due to non-
attendance (see 94-009r5) and that their membership would be
terminated if they did not attend this meeting. All organizations
were represented at this meeting.
The following organization joined X3T10 at the meeting:
Sequoia Advanced Tech., Inc.
The X3T10 membership is now at 57 organizations up from 56
organizations last time. Enclosure (1) is the list of the people
present at the meeting and enclosure (2) is the current X3T10
membership list.
4. Approval of Minutes - November Meeting Palm Springs, CA
(X3T10/94-227r1)
The minutes were approved as written.
5. Document Distribution
The 1995 mailing subscription fees have increased substantially ($410
for USA residents) because the mailing size has increased
substantially. Members who have any problems with their mailing
subscription should deal directly with Katrina Gray or Dan Arnold at
(202) 626-5741.
Larry Lamers requested that all documents for the next mailing be in
his hands by noon on Thursday January 28, 1995. Documents received
after this date will go into a subsequent mailing.
Larry Lamers reminded the committee of the requirements for document
submission to be included in the committee mailing. Since X3T10
meets its document archiving requirements by including the X3
Secretariat on the mailing list, documents included in the mailing
must be suitable for microfilming. This means that high-quality,
single-sided originals with adequate margins and proper
identification must be submitted. Document X3T9.2/92-84 R1 contains
the list of requirements for submissions.
In keeping with the X3T10 committee's new efforts for electronic
document filing and distribution, Larry requested that electronic
copies of all documents be made available to him. The electronic
copies can be sent directly to Larry. Or, the electronic document
can be placed on the SCSI BBS.
As usual, minutes are also available on the SCSI BBS (719-574-0424)
and will be distributed to the ATA and SCSI Reflectors. To be added
to the ATA Reflector, send an email to majordomo at dt.wdc.com with the
line 'subscribe ata your-email-address' in the message body. To
subscribe to the SCSI Reflector, send an electronic message to: scsi-
request at WichitaKS.NCR.COM.
The current document register is enclosure (3).
6. Call for Patents
This is a regular agenda item to identify any potential patent issues
with developing standards.
A document is available from ANSI, "Procedures for the Development
and Coordination of American National Standards", at no charge.
Annex I contains the ANSI patent policy.

8. Subgroup and/or Project Status Reports
8.1 Project Status Summary and X3/OMC Liaison [Lohmeyer]
John Lohmeyer said that the current X3T10 project status summary was
included on the backs of the meeting agendas. John also noted that
CBEMA had changed their name to Information Technology Industry
Council (ITI). Their email address is now: x3sec at itic.nw.dc.us.
8.2 X3T10.1 Task Group Report
The X3T10.1 Plenary met on January 10, 1995. No other meetings were
held since November 1994 plenary. 22 Principle members and 14 other
members attend the meeting.
The SSA-PH Draft, (989D-r3) is in preliminary review. Revision 3 was
distributed at the meeting. Revision 3 contains major (6 months
worth of) changes from revision 2. The meeting approved changes in
driver spectrum content values, (electrical I/F). Major editorial
work is still needed in the glossary, Intro, unitized connector
appendix; style changes throughout; and clean up connector drawings.
Action items have been assigned. There will be an editors meeting on
Jan17-19,1995 - Austin, Texas. The goal is mailing of revision 4 by
the first week of February.
The letter ballot on SSA-SCSI2 (13:0:0) was withdrawn due to many
procedural and technical problems. The editor's meeting will review
this document, if time permits.
The X3T10.1 plenary meeting approved motion to password protect
electronic versions of draft documents with password provided on page
2 in an editor's note, (12:0:1). The password is intended to avoid
inadvertent modifications, not a security feature.
Chair will revisit SD-4 project dates as part of annual report.
A working group meeting was authorized for March 6, 1995 in Newport
Beach, CA
8.3 SCSI Common Access Method (CAM) {Project 792-D} [Dallas]
Bill Dallas and John Lohmeyer reported that 792-D is in public
review. The review will end on April 4, 1995.
8.4 ATA Extensions (ATA-2) Status {Project 948-D} [Finch]
The ATA-2 working group completed its review of the proposed ATA-2
standard held at Western Digital on the December 1, 1994. The
result was the generation of ATA-2 revision 2j. At the ATA working
group held on Wednesday and Thursday of this week resulted in one
change to the 2j document, Annex F of the document was deleted. This
Annex dealt with typical device addressing on a PC compatible
systems. While the need for this information was felt to be
important, it was deemed not to be a requirement for the ATA-2
standard and that attempting to resolve the issues involved would
result in delaying the forwarding of ATA-2. Revision 2k was created
and will be in the next X3T10 mailing.
The ATA working group approved a motion to request that an X3T10
letter ballot be issued to ask the membership to approve forwarding
the ATA-2 working draft Rev 2k to X3 for further processing (first
public review). John Lohmeyer agreed to issue the letter ballot.
8.5 SCSI-3 Parallel Interface (SPI) Status {Project 855-D} [Lamers]
John Lohmeyer reported that 855-D is in second public review.
The review will end on April 4, 1995.
8.6 SCSI-3 Interlocked Protocol (SIP) Status {Project 856-D}
[Penman]
Duncan Penman reported that SIP revision 4a is ready. It will
be in the next mailing. Duncan has a few hardcopies for those who
need them immediately. John will put electronic copies on the BBS
and FTP site. Duncan asked working group time be allocated to
reviewing SIP.
8.7 Directly-Addressable Device Interface (DADI) Status {Project 964-
D} [open]
Gene Milligan moved that X3T10 process a withdrawal request for
Project 964-D (Directly-Addressable Device Interface). Bob Snively
seconded the motion. Gene Milligan noted that a near-future 1394
trade association meeting agenda includes a presentation from Martin
Freeman regarding P1285.
Bob Snively described the original concept, which was to provide a
memory-like interface to disk drives.
John Lohmeyer conducted a meeting vote whose results were: 34:0:0:23.
John accepted an action item to write a letter to X3 requesting that
Project 964-D be withdrawn.
8.8 SCSI Common Access Method -2 (CAM-2) Status {Project 990-D}
[Dallas]
Bill Dallas reported that the CAM working group met and came to
an agreement about formatting the CCB for SCSI-3, which requires
larger field sizes in several places. The general working group
agreed that the document title should be changed from CAM-2 to CAM-3
to avoid confusion. There was no objection from the plenary on
changing the title.
8.9 SCSI-3 Generic Packetized Protocol (GPP) Status {Project 991-DT}
[Stephens]
The GPP forwarding letter ballot passed 51:0:0:5. All comments
on the Gene Milligan (Seagate) yes ballot were resolved by the
working group. Paul Aloisi moved that the revised GPP be accepted as
resolving the letter ballot comments and be substituted for the
letter ballot version for forwarding to X3 for further processing
(first public review). Erich Oetting seconded the motion. The
motion passed 35:0:0:22. Gary Stephens took an action item to
prepare a revised GPP including the comments resolution. John
Lohmeyer took an action item to forward the revised GPP to X3.
8.10 SCSI-3 Serial Bus Protocol (SBP) Status {Project 992-D}
[Marazas]
Ron Roberts reported that 992-D is in public review. The review
will end on March 21, 1995.
8.11 SCSI-3 Fiber Channel Protocol (FCP) Status {Project 993-D}
[Snively]
Bob Snively reported that 993-D is in public review. The review
will end on March 21, 1995.
8.12 SCSI-3 Architecture Model (SAM) Status {Project 994-D} [Monia]
Charles Monia reported that 994-D is in public review. The
review will end on March 21, 1995.
8.13 SCSI-3 Primary Commands (SPC) Status {Project 995-D} [Weber]
Ralph reported that SPC revision 4 was in the previous mailing.
George Penokie provided detailed comments in 95-106r0. Those
comments were reviewed the working group meeting. Of the 21
comments, 15 were accepted. Comment 3 was accepted provided Ralph
will send the revised wording to George and Bob Snively for approval.
Comments 1, 7, 8, 9, and 13 were rejected because they conflict with
previously approved documents. George was satisfied with the reasons
for rejecting comment 8. However, George maintained that the MOVE
MEDIUM, READ ELEMENT STATUS, and processor commands should not be in
the SPC.
There had been some complaints about missing entries in the
Vendor-ID list in Annex E. John Lohmeyer and Ralph are revising
their procedures to avoid future problems. Charles Monia informed
Ralph that the parameter rounding material was removed from the SAM
last fall with the intent that it will be placed in the SPC. Ralph
was unaware of this change.
Ralph promised to generate SPC revision 5 for the next mailing.
However, he noted that his workload may make finishing on time
difficult.
Based on a comment from Rick Tewell, the committee discussed the
presence of references to CCS in the SPC. John suggested that the
topic be remanded to the working group.
8.14 SCSI-3 Block Commands (SBC) Status {Project 996-D} [Tewell]
Rick Tewell reported that the revision 0 of the SBC was in the
last mailing. George Penokie provided Rick with a list of approved
documents that affect the SBC. The approved documents will be
included in the next revision of the SBC.
8.15 SCSI-3 Stream Commands (SSC) Status {Project 997-D} [Lappin]
Ted Lappin reported that the working group on SSC met earlier
that day. SSC revision 2 will be in the next mailing. Ted will be
providing several proposals for the next mailing. He mentioned that
many of the density codes in the current table are not fully defined.
He suggested that such density codes may be changed to reserved if
fuller definition information cannot be obtained. Erich Oetting will
be writing a proposal for writing tapes without error recovery.
There also will be proposals on reading in flaky areas of the tape
and ASCs for cleaning tapes.
8.16 SCSI-3 Graphics Commands (SGC) Status {Project 998-D} [Tewell]
Rick Tewell has volunteered to act as Project Editor on the SGC
project. John Lohmeyer expressed his appreciation and asked the
committee to support Rick. Rick reported that revision 0 (a rehash
of the SCSI-2 graphics commands) will be ready for the mailing. Rick
will be contacting IT8 for information that affects the SGC.
8.17 SCSI-3 Medium Changer Commands (SMC) Status {Project 999-D}
[Oetting]
Erich reported on conceptual discussions on medium changer
improvements in the working group meeting. He reported that no
action was taken. Ralph Weber prepare a written proposal regarding
elimination of conflicts in operation codes for the MOVE MEDIUM and
READ ELEMENT STATUS. That proposal will be in the next mailing.
8.18 SCSI-3 Controller Commands (SCC) Status {Project 1047-D}
[Penokie]
George Penokie moved that SCC revision 4 be accepted as
resolving the letter ballot comments and replacing revision 3 for
public review. Gene Milligan seonded the motion. The motion passed
34:0:0:23.
John Lohmeyer took an action item to forward SCC revision 4 to
X3 for further processing toward public review.
8.19 Multimedia Command Set (MMC) Status {Project 1048-D} [Roberts]
Ron Roberts reported that the MMC working group met earlier this
week. The working group received a copy of a Sony proposal for CD-
ROM commands. That proposal was not reviewed because Sony was unable
to attend the working group meeting due to weather problems. Ron
requested authorization for an MMC working group meeting in Santa
Clara on February 2nd. Western Digital is creating a reflector for
MMC issues. The reflector address will be mmc at dt.wd.com. Reflector
sign-up messages should be sent to majordomo at dt.wd.com with the line
`subscribe mmc' in the message body.
8.20 SCSI-3 Fast-20 Parallel Interface (Fast-20) {Project 1071-D}
[Lamers]
The letter ballot passed 50:2:0:4. The negative votes came from
IBM and Gene Milligan (Seagate). Larry reported that all the
comments have been resolved. Larry Lamers reviewed the letter ballot
comments and responses. The comments and responses are covered in
the working group meeting minutes, 95-129.
Larry promised to make a new revision of Fast-20 as soon as
possible. Larry Lamers moved that X3T10 accept the resolution of the
Fast-20 letter ballot comments, as recommended by the working group.
Gene Milligan seconded the motion. The motion passed 36:0:0:21.
8.21 AT Attachment-3 Interface (ATA-3) Status {Project 2008-D}
[Milligan]
Gene Milligan reported on the work of the ATA-3 ad hoc group
meeting. Early proponents of the ATAPI expressed opposition to X3T10
working on ATAPI prior to "final review" by SFF. Consequently, the
ad hoc was not able to generate the ATAPI plan and schedule as yet.
A presentation was given on ATASPI which has been offered to the
industry for an ATA industry API.
The ad hoc agreed on scope relative to command overlap and
queuing. The ad hoc requested that the ATA-3 project editor include
the security mode, check power mode, device 1 only description, and
DMA Identify command in the initial draft. The ad hoc extended the
deadline to the February 15 meeting for PFA, revision reporting, host
information, and dynamic power selection. Gene reported that the ATA-
3 project is on schedule.
Gene Milligan moved that X3T10 accept the ATA ad hoc's
recommendation to include: (a) "weak command overlap"; (b) "strong
command overlap"; and (c) "command queuing" in the ATA-3's scope and
to establish high priority on (a) with diminishing priority on (b) to
(c) -- ultimately dropping (b) and/or (c) to ATA-4, if it (or they)
delays accepting the definition beyond February 16, 1995, from ATA.
Richard Kalish seconded the motion. The motion passed unanimously.
John Lohmeyer said that his reading of the ATA-3 project
proposal suggests that all the concepts in the above motion can be
interpreted as being part of the project and asked if there were any
objections to his interpretation. There were no objections. Thus,
no revision of the project proposal was undertaken.
8.22 ATA Packet Interface (ATAPI) Status {Project ____-D} []
The ATAPI project proposal was on the OMC agenda for this week.
Approval of the project proposal by X3 letter ballot is anticipated
before the next X3T10 meeting.
8.23 XOR Commands Study Group [Houlder]
Reporting for Gerry Houlder, Gene Milligan said that this week's XOR
meeting had higher attendance, with a lot of people contributing to
the discussions. This indicates a higher level of interest in this
topic. Complete minutes will be in document 95-114.
9. Old Business
9.1 X3T10 Procedures [Lamers]
Since Larry has not yet had time to prepare draft procedures, John
said he would remove this agenda item until we have a proposal.
9.2 X3T10 Standards Development Policy and Procedure (94-198)
[Milligan]
Gene Milligan led a discussion of 94-198r3. He reported on the
history of how the document was developed. Lengthy electronic mail
discussions, one working group meeting, one study group meeting, and
a review with X3T10 Chair Lohmeyer all were performed to create the
document revision presented to this meeting.
Gene Milligan moved that X3T10 accept the revised document as an
acceptable response to the letter ballot comments. Ron Roberts
seconded the motion. Gene Milligan moved that consideration of the
above motion be deferred until March 9th. Ron Roberts seconded the
motion. The motion to defer consideration passed unanimously.
9.3 Clarification of international program fee [Allan]
Dal Allan was absent from this meeting. Therefore, this agenda item
was carried over to the March Plenary meeting.
10. New Business
10.1 Letter Ballot Results and Resolution
John Lohmeyer reported the results of the two letter ballots (see 95-
123).
10.1.1 Forwarding SCSI-3 Fast-20 to X3 (94-248)
10.1.2 Forwarding GPP to X3 as a Technical Report (94-249)
10.2 Immediate Commands (94-244r1) [Lappin]
Ted Lappin reported on working group revisions to 94-244r0. The
proposal modifies the SPC slightly to allow reporting of progress
information on all immediate commands (not just immediate FORMAT
commands). There was a brief discussion which reveled a new issue.
Since consensus was not immediately forthcoming, the question was
remanded to the working group.
10.3 Exception Handling Selection Mode Page (94-190r4) [Penokie]
George Penokie reported that the working group unanimously
recommended 94-190r4 be accepted for inclusion in the SPC. George
moved that 94-190r4 be accepted for inclusion in the SPC. Bob
Snively seconded the motion. The motion passed unanimously.
10.4 Conflict between READ LONG and Read/Write Error Recovery Page
[Milligan]
Gene Milligan moved that X3T10 accept the working group's
recommendation to rescind document X3T10/94-077 resolution to the
READ LONG CORRCT bit and Read/Write Recovery Page and to make the
following changes to SBC: (1) Add test to READ LONG that states that
READ LONG is a command whose definition is independent of the
Read/Write Error Recovery Page, but does allow retries; (2) Add text
to define that a READ LONG command with CORRCT=0 should result in
GOOD status unless data cannot be transferred for some reason other
that non-correctable errors.
Jim McGrath seconded the motion. The motion passed 33:0:0:24. Gene
took an action item to prepare a written proposal for changing SBC.
10.5 ATA Systems Issues Study Group [Penman]
Duncan Penman reported on a reflector discussion regarding the need
for a study group to investigate ATA systems issues (BIOS, software,
etc.). The synopsis of the reflector discussion can be found in
document 95-133. In the absence of objections, John authorized a
study group effort to be lead by Duncan. Currently, there are no
plans for study group meetings. The discussion will be conducted via
electronic mail. The study group will be called the "System issues
study group."
11. ISO [Milligan]
Gene Milligan, the X3T10 International Representative, gave an oral
report and provided the following electronic report:
ISO Report 1/95
SC 25 Working Group 4 has distributed N626 which is a
contribution from Professor, Doctor Oehler on Interfaces of active
components to the cabling. Grivna has requested a list of references
to convert from EIA to IEC component standards for Fibre Channel. A
new ISSBN1695 document dated 94/11/30 SD9 Memorandum of Agreement
for US TAGs has been distributed.
The enclosed list of ISO documents since the last SC 25 meeting
includes nine International Standardized Profiles relating to the
X3T12 FDDI work.
The SC 25 Secretary Walter v. Pattay has sent a 94/12/04
letter to Chairman Fujisaki appointing Gene Milligan as the SC 25 to
SC 26 Liaison. SC 26 is the ISO group responsible for microcomputer
systems.
ISO/IEC is working on a process to publish de facto
specifications. Some information has been distributed JTC1N3142
94/12/06 Transposition of Publicly Available Specifications -
Management Guide Plan.
Interoperability of implementations (as opposed to standards
conformance) is starting to receive ISO attention as noted by
JTC1N3325 94/12/06 Req for SWG-CA study of product interoperability.
The US contact for Interoperability SWG-CA is the Chair of JTCA Dave
Thewlis, of Share Inc. at 71210.76 at compuserve.com.
The SC 25 Secretary has decided not to precisely follow the
action item to request that the JTC 1 Secretariat, ANSI, reverse
their interpretation that the HIPPI and FC new work items failed.
Instead he has decided to, on the basis of the passing CD ballots,
submit the HIPPI-FP, LE, SC, & FC-PH DIS documents and resolution of
CD comments to JTC 1 for the registration of DIS ballots. The HIPPI-
PH is ready for IS publication as soon as an editor's report on DIS
ballot comments is received. X3T11 is addressing these items.
A revision of the ISO/IEC procedures is now available as
JTC1N3348 94/12/20 Procedures for the Technical work of JTC1 - Third
Edition.
JT94-0717 94/12/21 provides a Timeline for JTC1 Strategy for
Implementation of Information Technology. The X3T10 IR has requested
additional information from the US contact Karen Higginbottom,
higginbottom @ cup.hp.com, on both the international and US activity
on electronic mechanization.
12. Liaison Reports
12.1 X3T11 Liaison Report [Cummings]
X3T11 met on December 7, 1994 with 90 attendees. One member
organization was added (TV/COM), bringing the membership of X3T11 to
54.
It was reported that X3.230-1984, FC-PH, and X3.254-1994, FC-FP, had
both completed BSR review, and were with the ANSI editors for pre-
publication editing. The requests to withdraw the IPI-2 Tape (X3.176-
1990) and IPI-3 Communications (X3.177-1990) standards had also
completed BSR review and were being actioned.
The FC-SB (Revision 3.3) and FC-AL (Revision 4.4) drafts have
completed OMC compliance reviews and have been assigned X3.271-199x
and X3.272-199x respectively. First Public Reviews will commence on
both drafts early in 1995.
A new naming convention was approved by a vote of F30-O01-NV23. By
this change FC-EP will become FC-PH-2 and subsequent generations of
all FC projects will follow this convention.
Four project proposals were forwarded for further processing. They
were:
1) For an amendment to the HIPPI-SC standard, by a rollcall vote of
F38-O00-NV16
2) For a Technical Report on HIPPI-Serial, by a rollcall vote of F40-
O00-NV14
3) For an FC-PH-3 standard, by a rollcall vote of F36-O00-NV18
4) For a Technical Report on a 10 bit interface, by a rollcall vote
of F36-O00-NV18
Letter Ballots for the Revised IPI-3 Disk and Revised IPI-3 Tape
projects for a first Public Review, and for the withdrawal of Project
782-D (HIPPI-IPI3) were not issued in advance of the Plenary as had
been expected, but are expected to be issued early in the New Year.
A Letter Ballot for the SBCON Project Proposal was also not issued as
authorized in October, due to ongoing debates and changes to the
proposal, but a new Letter Ballot on a revised SBCON Project Proposal
was authorized for issuance subsequent to the meeting. A request for
written arguments for
and against adoption of the Proposal to accompany the ballot was
accepted.
12.2 SFF Industry Group [Allan]
Jim McGrath reported on the progress in connector design progress
this week and urged participation in the SFF meeting tomorrow. Bill
Ham reported that the very-high density connector SFF group may
produce one or two connector choices that will be forwarded to X3T10
for consideration.
12.3 IEEE P1394 [Marazas]
Jerry Marazas provided the following electronic report:
The proposed IEEE Standard 1394, High Performance Serial Bus had
successful closure of the IEEE administered ballot on December 22,
1994.
The results are summarized as follows:
144 People in Ballot Pool (an unusually large number)
133 People eligible to vote upon the ballot
84 Afirmative Votes
6 Negative Votes
10 Abstentions
The 75 per cent criteria was achieved ==> 100 votes / 133 Eligible
The ratio of affirmative votes is 93 per cent ==> 84 Yes / 90 votes.
The IEEE procedures provide for a comments resolution process to be
conducted by the given Working Group ( P1394 WG in this case). To
execute this process I have directed that a 30 day ballot be
submitted to the voting members (some 29 people) of the P1394 Working
Group. The ballot closes February 6, 95.
The ballot provides:
<> The P1394 Working Group authorize a Ballot Resolution Committee
to act
on its behalf for the purpose of executing the IEEE comments
resolution procedure.
<> The Ballot Resolution Committee (BRC) specifically consists of a
named slate of persons which are to be approved as a block by
the Working Group ballot.
<> Participation in the BRC meetings is open and not limited to the
authorized slate of members.
<> Notice of BRC meetings is to be posted to reflectors maintained
in
support of (a) the P1394 Working Group, (b) the P1394 Trade
Association, and (c) the X3T10 committee.
The work of the BRC requires that each comment (both positive and
negative ballot comments) is to be formally placed in writing
(verbatim), and a disposition made indicating acceptance or rejection
of the comment. In many instances, the disposition will result in
changes to the P1394 draft standard. A written reply is to be sent
each comment submitter indicating the disposition.
It is my expectation that comments are sufficiently numerous and
sufficiently detailed that the BRC will find it necessary to produce
a new draft of the proposed standard. Such new draft, upon its
completion by the BRC, will be given to the IEEE so that it may
submit the document to the P1394 ballot pool for a vote as to
acceptability of comments resolution.
In anticipation of an affirmative vote by the P1394 Working Group as
to authorization of the BRC, I have posted announcement of the first
meeting of that committee. The first BRC meeting will be hosted by me
in Boca Raton at the IBM PC Company main site on February 14, 15, and
16, 1995. I expect additional BRC meetings will be necessary. It is
my desire to schedule the second BRC meeting to occur during X3T10
week at the March 6-10 series of meetings in Newport Beach,
California. Subject to X3T10 approval (as well as host approval) I
wish the March meeting of the BRC to occur Monday, Tuesday,
Wednesday, of X3T10 week. The Monday start time would be 1 PM. The
Tuesday and Wednesday start times would be at 9 AM.
12.4 IEEE P1285 Status [Pak]
Dennis Pak provided as written report in document 95-128r0. Key
elements of the report are as follows. The collaboration with P1596
SCI is finishing up. Another co-located meeting will be held on
January 12. The beta level data structures have been updated to allow
for both 32-bit and 64-bit operation. A new P1285 document update is
imminent. The beta level and gamma level portions of the document
have already been updated.
New features include: - Mover capability: the reporter - Setup
command for 64-bit addressing - Event handling support -
Scatter/Gather for beta level - Command pre-fetching support for
the beta levelFuture meetings are scheduled as follows: January
12 Co-located Meeting with IEEE 1596, Santa Clara University, Bannon
Engineering Building
Meetings are usually scheduled from 2:00-5:00 PM. Comments and/or
questions should be forwarded to Martin Freeman, IEEE P1285 Chair,
@(415)354-0329. His e-mail address is
martin at savant.PRPA.Philips.COM.
12.5 PCMCIA Report [McLean]
Pete McLean reported that PCMCIA has publicly announced the next
revision of their standard. Several loose ends were discovered in a
recent review of that revision. Pete anticipated final adoption at a
meeting near the end of January. Pete described a shrouded connector
that will allow higher bus speeds. The connector appears headed for
inclusion in PCMCIA.
12.6 AIIM C21 [Podio]
John Lohmeyer noted that Fernando Podio had attended the SCSI Working
Group meeting on Wednesday and that there had been unanimous consent
on resolving the remaining issues involving how to document the log
and mode pages (see 95-129 for details).
13. Review of Action Items
62) Larry Lamers will generate the SCSI-2 responses document for
distribution to ISO via the IR.
63) Larry Lamers will prepare a final ISO version of SCSI-2.
64) Gene Milligan will double check the ISO status of all forwarded
dpANS documents and to generate new ISO work items for any
lacking an approved ISO project, with the exception of ATA.
67) John Lohmeyer will obtain an electronic copy of the new X3 SD-2
and post it on the SCSI BBS and on the FTP site.
68) Larry Lamers will conduct a letter ballot regarding the
forwarding ATA-2 to X3 for processing toward first public
review.
69) John Lohmeyer will send a letter to X3 requesting withdrawal of
Project 964-D (Directly-Addressable Device Interface).
70) Gary Stephens will prepare a revised GPP for forwarding.
71) John Lohmeyer will forward the revised GPP to X3 for further
processing.
72) John Lohmeyer will forward SCC revision 4 to X3 for further
processing toward public review.
73) Gene Milligan will prepare a written proposal for changing SBC
based on the motion approved
under agenda item 10.4.
14. Meeting Schedule

Other Activities John Lohmeyer (719) 573-3362
john.lohmeyer at hmpd.com
John presented a foil of a letter from Joe Molina of the RAB
complaining about the X3T10 meeting locations for the November `94
and January `95 meetings. This engendered a lengthy discussion on
site selection criteria. Of course, each person had his/her favorite
criteria, which often conflicted with other's criteria. Some key
points made were: a) locations should have convenient air
transportation; b) locations should be situated so that component
vendors can combine trips with customer visits; c) locations should
be selected that have reasonable hotel rates; d) risky travel
locations should be avoided (e.g., mountains in winter, Florida in
hurricane season); e) avoid repeated locations in the same geographic
area; f) restaurants and other business services should be convenient
to the hotel; etc.
It was noted that Palm Springs (and to a lesser degree, Lake Tahoe)
actually met many of the above criteria. Few people could remember
getting better hotel rooms at any rate. Those who actually attended
the meetings were generally pleased with the location. However, it
was suggested that resort locations should be restricted to no more
than once per year to balance the other criteria.
The long-term X3T10 meeting week schedule is:

Volunteers to host 1996 meetings should contact John Lohmeyer.
14.1 Authorization of Working Group Meetings
John noted that the working group meetings are required to operate
under the same voting procedures as does X3T10 (that is, one vote per
organization) and the results of a working group are not binding on
the parent committee. This later requirement is why we have
traditionally only used non-binding straw polls in working group
meetings. Any issue where the voting rules would make a difference
should be deferred to the plenary group. Nonetheless, task groups
and ad hocs should strive to achieve consensus prior to bringing
issues to X3T10.
Jim McGrath moved and Erich Oetting seconded that X3T10 authorize the
X3T10-related meetings and events in the list above. The motion
passed unanimously.
15. Adjournment
The meeting was adjourned at 5:35 p.m. on Thursday January 12, 1995.
