Results of Meeting
1. Opening Remarks
John Lohmeyer, the Acting Chair, called the meeting to order at 1:00 p.m.,
Thursday March 17, 1994. He thanked Skip Jones of QLogic Corp. for arranging
and hosting the meeting. John said that he had copies of the call for
volunteers to Chair X3T10 for anyone who wishes to apply.
Gary Stephens announced that Bill Spence has suffered another coronary event.
Gary distributed get well cards so that committee members could express their
sympathies. Dal will insure that the cards get delivered to Bill.
John said that X3 Subgroup Membership forms and 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. The X3 Membership forms and the X3T10 Mailing Subscription
forms should be mailed 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 additions:
14.3 Notification of Meeting Hosts Regarding Schedule Changes
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.
This year, the International Participation fee ($300) will be billed
separately directly from ANSI. Payments must be received by April 8, 1994
or the membership will be dropped and the organization will not be permitted
to vote or receive mailings.
The X3T10 membership is now at 60 organizations, with no changes since the
first meeting. Enclosure (1) is the list of the people present at the
meeting and enclosure (2) is the current X3T10 membership list.
John distributed a CBEMA list of the committee membership. John recommended
filling out an address correction form (on the documents table) if the
information on the CBEMA list is incorrect.
4. Approval of Minutes - January Meeting San Diego, CA (X3T10/94-016r1)
The minutes were approved as written.
5. Document Distribution
Members who have any problems with their mailing subscription should deal
directly with Katrina Gray at (202) 626-5741.
Larry Lamers requested that all documents for the next mailing must be sent
so as to be received by noon on Friday, March 31, 1994. 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.
As usual, minutes are also available on the SCSI BBS (719-574-0424) and will
be distributed to the SCSI Reflector E-mail list. To be added to the SCSI
Reflector, send an electronic message to: scsiadm 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. The last page
contains the ANSI patent policy.
7. Review of Old Action Items
1) John Lohmeyer will contact AIIM regarding AIIM activities. Complete.
John contacted Judy Kilpatrick and discovered that Ken Hallam is
coordinating this work. Ken has agreed to act as liaison.
2) John Lohmeyer will contact Fernando Podia regarding liaison reports.
Complete.
3) Larry Lamers will incorporate the correct patent statement in the dpANS
AT Attachment and will send a copy to the X3 Secretariat. Complete.
4) On behalf of X3T10, John Lohmeyer will submit a public review comment
against SPI requesting that SCAM be incorporated. Complete.
5) John Lohmeyer to progress the SCC project proposal to X3. Complete.
6) John Lohmeyer to progress the MMC project proposal to X3. Complete.
7) John Lohmeyer to discuss combined TC/TG mailing with X3 Secretariat.
Complete -- They are willing to do combined mailings.
8) Gene Milligan to revise project proposal on GPP. Complete.
9) John Lohmeyer to contact the X3 Secretariat regarding electronic SDs.
Complete -- The SD-2 and SD-3 are posted on the SCSI BBS.
8. Subgroup and/or Project Status Reports
8.1 Project Status Summary [Lohmeyer]
John Lohmeyer presented the current X3T10 project status summary. He noted
no major changes from previous reports. Details of project status for each
project will be presented below.
8.2 X3T10.1 Task Group Report [Scheible]
Substituting for John Scheible, Ken Hallam reported on meetings to define the
documentation for transceivers and connectors. The meetings chose to
document connectors in sufficient detail for successful interoperable
implementations. For transceivers, the group decided to inspect existing
transceivers specifications. Several key aspects of the inspected
specifications were chosen for inclusion in the standard. Bill Ham noted
that shield requirements also would be a critical part of the specification.
In the X3T10.1 meeting, John Scheible promised to get an IBM patent statement
by the May meeting. John also will have a word-format version of the SSA-PH
document by May. The meeting voted unanimously to request identifier codes
|from PCI. The meeting considered a new internal cable.
X3T10.1 is calling for volunteers to chair the committee. There have been
some problems getting volunteers. However, Ken felt that this is no longer
a problem.
8.3 SCSI-2 Status [Lamers]
John Lohmeyer reported that SCSI-2 was approved by the ANSI Board of
Standards Review on January 31, 1994. It will be designated X3.131-1994.
Publication is expected soon.
Larry sent a copy to Bob Hager for ANSI publication.
Dal Allan noted that 4796 copies of SCSI-2 have been sold by Global
Engineering.
8.4 SCSI Common Access Method (CAM) [Dallas]
Bill Dallas reported on the CAM editing session this past Monday. See 94-073
for details.
8.5 AT Attachment Status (ATA) [Lamers]
AT Attachment is out for letter ballot at X3. The letter ballot closes on
March 30, 1994.
8.6 ATA Extensions (ATA-2) [Finch]
Steve Finch reported that the last meeting of the ATA Working Group was held
Monday, March 14. A total of 22 persons were in attendance. Issues
discussed included: 16.6 MB/s transfer rates, electrical signal definitions,
and issues relating to improving the ATA-2 document in the areas including
but not limited to: ATA DMA issues, power management issues, and
Master/Slave hardware issues.
Also discussed were the ATA-3 Project Proposals. The working group expressed
reservations that their approval might impact ATA-2. After some discussion,
it was unanimously agreed that the project proposals should be approved so
that parallel development of advanced features could begin.
8.7 SCSI-3 Architecture Model (SAM) Status [Monia]
Charles Monia described a working group review of SAM revision 12a. The
review primarily was to inform members of changes in SAM. Charles noted that
he will be revising the document for distribution in the next mailing.
Gene Milligan moved that all options in all protocol standards produced by
X3T10 be changed to mandatory. Ed Gardner seconded the motion.
Gary Stephens noted that allowing options in protocol standards creates a
scenario where the entities at both ends of the wire (the protocol) are
capable to transact an operation but the wire will not transmit the
description of the operation. This problem arose from a working group debate
regarding options in FCP. About half a dozen persons spoke against the
motion. A motion to end debate passed 41 to 1.
The motion was defeated, 1 to 33.
8.8 SCSI-3 Parallel Interface (SPI) Status [Lamers]
John reported that public review closed on February 25, 1994. One comment
was received, from X3T10. The comment asked that SCAM be added to the
standard.
8.9 SCSI-3 Interlocked Protocol (SIP) Status [Lamers]
No status change. John reported that efforts have been made to find help for
editing SIP.
8.10 SCSI-3 Generic Packetized Protocol (GPP) Status [Stephens]
At the last meeting, X3T10 voted to re-direct this project to be a Technical
Report instead of a standard. John noted that a motion to reconsider was
expected under agenda item 9.2.
8.11 SCSI-3 Serial Bus Protocol (SBP) Status [Marazas]
Gerry Marazas reported that numerous written comments were received on a
letter ballot for forwarding SBP. A meeting was held earlier this week to
review and resolve the letter ballot comments. There will be a new SBP
revision (16) based on the letter ballot comments and their resolution.
Revision 16 will be available for the next mailing.
John warned the membership to expect a forwarding letter ballot for SBP.
This was followed by a lengthy discussion of the general policies for
forwarding documents and the specific actions this case.
In summary, there will be a letter ballot for SBP forwarding to X3 sent to
principle representatives. A copy of the SBP document to forward will be in
the mailing. A copy of the comments and responses also will appear in the
next mailing.
8.12 SCSI-3 Fiber Channel Protocol (FCP) Status [Snively]
John reported that the FCP letter ballot passed 47:2:0 (11 ballots not
returned). There were two yes with comments ballots.
Bob Snively reported on the working group activities to resolve no votes on
the FCP letter ballot. Bob promised to provide a complete comments
resolution document. Bob reported that some major technical issues have not
been resolved. Bob described the actions that he will take from this point
forward. Those actions include directly mailing a revised FCP to committee
members prior to two-weeks before the next plenary meeting.
Bob described the resolution of the following major technical issues.
PRLI/PRLO -- PRLI is optional. PRLI acts only on an image pair.
Class 3 interlock -- Class 3 requires an interlocking protocol definition in
FCP. Class 3 is desirable in some situations. Bob is not sure whether the
interlock definition will be added or Class 3 will be prohibited in FCP.
FQXID -- Must be extended for process associators and XID invalidation.
LUN 0 -- Bob requested that SAM define the ability to retrieve collective
device capability information at LUN 0. This produced short discussion with
no resolution.
Data Count -- There is a general lack of agreement between SBP, SSP, and FCP
regarding data length information within the protocol. There is no
resolution yet.
Fiber Channel Nports -- There is a limit on resources in ports that can block
delivery of a task management function. A warning about this problem will
be added.
8.13 SCSI-3 Primary Commands (SPC) Status [Weber]
Generation of the first draft of SPC has progressed as far as the INQUIRY
command.
8.14 SCSI-3 Block Commands (SBC) [open]
John reported that there still is no project editor. Hopes were high
regarding the gentleman from Samsung. However, since the gentleman was
absent from the meeting, hopes were deflating quickly.
8.15 SCSI-3 Stream Commands (SSC) [Lappin]
Ed Lappin reported that a SSC document has been drafted for the next mailing.
There were questions about the correct home for the processor commands.
Ralph noted that the January meeting expressed a preference for putting the
processor commands in the SPC.
8.16 SCSI-3 Graphics Commands (SGC) [open]
A project editor is being sought. John noted that, if no editor can be found
in X3T10, he would be interested in a coordinated effort with AIIM and
possibly IT8.
8.17 SCSI-3 Medium Changer Commands (SMC) [open]
A project editor is being sought. There is an old draft from Gary Stephens
is available. Questions were raised regarding the relationship of medium
changer commands in SPC and the SMC document. That relationship is defined
in X3T9.2/92-006R1 (an approved committee document).
8.18 Directly-Addressable Device Interface (DADI) []
No formal report. Jim McGrath noted a possible interaction with ongoing
PCMCIA work.
8.19 SCSI Common Access Method -2 (CAM-2) (93-082) [Dallas]
Bill Dallas reported that no work will be undertaken until CAM (classic) is
ready for second public review.
8.20 SCSI-3 Serial Storage Protocol (SSP) [Scheible]
Ken Hallam reported that the SSP group met. All activities of the group are
recommendations. The project proposal has not been approved yet. The group
is recommending that autosense be a mandatory part of the SSP standard. Ken
noted that SSP autosense data would be transferred before status is
transferred.
John Lohmeyer stated that the SSP project proposal will go to OMC next week.
Steve Finch moved that upon approval the SSP project be assigned to the
X3T10.1. Ed Gardner seconded the motion. Multiple tens of minutes were
devoted to discussing how best to schedule protocol/physical issues meetings.
John noted that the concern that originally put SSP in X3T10 was the
structural separation of X3T9.7 and X3T9.2. That is no longer a problem.
The work of X3T10.1 will be forwarded to X3T10.
The motion passed 10 to 6. (John noted that apathy won 25 to 16.)
8.21 SCSI-3 Controller Commands (SCC) (93-130) [Penokie]
John reported that the SCC project proposal will be on the OMC agenda next
week.
8.22 Multimedia Command Set (MMC) [Harris]
Norm Harris distributed a revision 0 of the document at the working group
meeting. The document includes the CD-ROM command set. Norm is looking for
input regarding additional commands, particularly disk commands for multi-
media.
Concerns were raised regarding the cover page currently in use. John
promised to work with Norm to make the cover page reflect the absence of an
approved project proposal.
8.23 Replacement of ANSI X3.80-1988, Interfaces Between Flexible Disk
Cartridges and Their Host Controllers, with ISO 9315:1989.
In April '93, X3T9.2 voted to recommend that simultaneous withdrawal of
X3.80-1988 and adoption of ISO 9315:1989 as an ANSI standard. X3T9 accepted
this recommendation and voted to make the same recommendation to X3. The
public review period closed February 13, 1994. No comments were received.
The recommendation is now at X3 letter ballot, which closes April 20, 1994.
8.24 RAID Study Group [Penokie]
George Penokie reported on the two RAB meetings since the last plenary.
George was pleased to report that the new component logical unit (C-LUI)
concept goes a long way towards solving the dual-controller issues identified
in February. George will be building a new revision of the SCSI Disk Array
Model (94-040r3) for inclusion in the next mailing. The new revision will
include new C-LUI Services; Attach C-LUI; and Report C-LUI. The new revision
will include several modified services; Report P-LUI/C-LUI Identifier, Set
P-LUI/C-LUI Identifier, Exchange P-LUI/C-LUI, Remove P-LUI/C-LUI, Add
P-LUI/C-LUI, Create/Modify P-LUI/C-LUI Spare, and Report P-LUI/C-LUI Spare.
A request for a new general service also will be honored in the next
revision; Report P-LUI/C-LUI Attachment/Association.
George reported that no changes have been requested in the SCSI-3 Addressing
document (94-031r2). It will be submitted to X3T10 as soon as practical.
George reported that the SDA Commands and Mode Page document (94-042r2) must
be revised to reflect the C-LUI changes. George reported that the SDA States
and Types document (94-041r2) also requires changes to reflect C-LUIs.
George reported that the Error Handling for SCSI Controllers document
(94-024r2) contains a very long list of proposed new ASC/ASCQ codes. George
and others feel that the proposed ASC/ASCQ list needs to be scrubbed.
The complete RAID Study Group minutes can be found in X3T10/94-062.
9. Old Business
9.1 Technical Information Bulletins
Gary Stephens had prepared a TIB on the tape partition issue. Folks are
advised to review it. It is anticipated that a forwarding motion will be
taken soon.
Gary noted that a very old TIB on LOG SENSE (X3T9.2/90-165) also needs
processing. John took an action item call Lynn Barra to resurrect the LOG
SENSE TIB.
9.2 Revised GPP Project Proposal [Milligan]
Norm Harris reported that Adaptec, after internally discussion, had concluded
that discussion was terminated prematurely on the motion to change GPP to a
technical bulletin. Therefore, Norm moved that the previous decision be
reconsidered. Dal Allan seconded the motion.
After a lengthy discussion, the committee reached a point where further
alternative action was generally desired. Insufficient information was
available regarding specific changes in scope for GPP. No preferred
direction could be found for action with respect to project proposal changes
or GPP document changes. John asked if there were any objections to
withdrawing the motion to reconsider. No objections were heard and, in
effect, action on GPP was deferred to the next Plenary meeting.
10. New Business
10.1 Results of SPI Public Review
John reported that public review closed on February 25, 1994. One comment
was received, from X3T10. The comment asked that SCAM be incorporated in the
standard as a normative annex.
Ed Gardner moved that the public review comment be accepted by X3T10. Gene
Milligan seconded the motion. The motion passed 39:1:0:20. Larry Lamers
took the action item to incorporate SCAM in SPI.
10.2 Results of Flexible Disk Public Review
The public review period closed February 13, 1994. No comments were
received. The recommendation is now at X3 letter ballot, which closes April
20, 1994.
10.3 Results of FCP Letter Ballot
John reported the FCP letter ballot results:
FCP Letter Ballot Results: 47 Yes, 2 No, 0 Abstain, 11 Did not return ballot
Yes, with
comment: IBM, Unitrode
No: FSI, Seagate
Did not
return ballot: Advanced Micro Devices, Cirrus Logic, Conner Peripherals,
Distributed Processing Technology, Harting Electronik,
Maxtor, National Semiconductor, Oak Technology, P. E.
Logic, Rancho Technology, and Samsung
FCP has passed this ballot, but X3T10 must make an effort to resolve the
comments. Since Bob Snively, FCP Editor, cannot complete this effort prior
to the mailing deadline, the current plan is for Bob to mail a revised FCP
document directly to the X3T10 members at least two weeks prior to the May
'94 X3T10 meeting.
Expect motions to approve the responses and to approve the substantive
changes to FCP at the May meeting.
John accepted an action item to distribute the FCP voting results and
comments to the SCSI and FC Reflectors.
10.4 Review of new documents
Steve Finch noted his new document (94-072) describing errors in SPI.
Steve Finch presented a document describing Updated Mode 4 16.6 Mbyte/sec
timing for ATA-2 (94-045r2). Steve asked everyone consider this document
carefully. He will be seeking an approval vote at the next Plenary meeting.
10.5 Withdrawal or Reaffirmation of ANSI X3.170-1989, Enhanced Small Device
Interface (ESDI)
The ESDI standard is up for its five-year review cycle. Jim McGrath moved
that X3T10 recommend reaffirmation of ANSI X3.170-1989, Enhanced Small Device
Interface (ESDI). Ed Gardner seconded the motion.
A clarification of the options was requested. John noted that withdrawal or
reaffirmation will included a four month public review. Gene Milligan noted
that the ISO version of the ESDI standard is close to publication. The
motion passed 39:4:0:17. Three no votes were based on the belief that ESDI
is a dead interface. John took an action item to inform X3 of the decision
to reaffirm ESDI.
10.6 Forwarding motions on ATA-3 Project Proposals (ATA3-PH, ATA3-XPT, ATA3-
PI, and ATA3-BC)
Steve Finch moved that Project Proposals for ATA3-PH, ATA3-XPT, ATA3-PI, and
ATA3-BC be forward to X3. Bob Masterson seconded the motion.
Concerns were raised about the scope sections in ATA3-PI and ATA3-BC. The
two scope sections are virtually identical. John asked if there were any
objections to withdrawing the motion to forward. No objections were heard.
John announced that all four project proposals will be processed using letter
ballots.
Owing to general confusion regarding the proposed ATA-3 document set, Steve
Finch reviewed the ATA-3 document relationship diagram.
10.7 SPI-2 Project Proposal and Ultra SCSI Status Report [Ham]
John requested guidance from the committee regarding how best to standardize
the Ultra SCSI work already in progress. Options considered were creating
a new project proposal and folding Ultra SCSI in SPI. Many representatives
noted the industry excitement regarding Ultra SCSI and hoped that its
standardization could proceed as quickly as possible.
John noted a couple key don'ts expressed by the committee. Don't tie Ultra
SCSI to a connector. Don't unnecessarily break upward compatibility from
Fast SCSI to Ultra SCSI.
John thanked the committee for their advice.
Bill Ham reported on the break-neck progress of the Ultra SCSI work. Since
the beginning of the year, several meetings have gathered the silicon vendors
and system houses interested in Ultra SCSI. Much performance data and signal
integrity data have been collected and reviewed.
10.8 Authorization to edit SPI document
Dal Allan moved that X3T10 authorize editing work per the quotation in 94-
082. Erich Oetting seconded the motion. The motion passed unanimously.
10.9 Call for Volunteers - X3T10 Chair, Vice-Chair, and International
Representative
John announced that there are a calls for volunteers for X3T10 chair and
vice-chair.
11. ISO [Milligan]
Gene Milligan, the acting X3T10 International Representative, gave an oral
report and provided the following electronic report:
ISO Report
March 1994
At the last series of meetings the acting IR reported that he
expected the changes at the SC 25 Secretariat with the appointment
of Walter v. Pattay would result in significant improvements in the
processing time of the international versions of our standards
projects. This has proved to be correct and their is now a plethora
of international matters to act upon.
Somewhat ironically, with the renewed vigor at SC 25 the retirement
of X3T9 without having taken a position on how the ongoing SC 25
work should be handled could have slowed the activity on the U.S.
end. Although the SC 25 TAG Secretariat and the SC 25 WG 4
Secretariat had not been informed of any official transition plan
the acting IR has unilaterally informed them that he would be the
acting IR for X3T10, X3T11, and X3T12 until further notice. This
will enable ongoing processing hopefully without interruption. The
SC 25 Secretary has been informed of essentially the same
information.
In addition to numerous liaison statements which the July SC 25/WG
4 delegation can address in executive session, the following items
have been issued by the SC 25 Secretary or the JTC 1 TAG
Administrator which require action by X3T10, X3T11, or X3T12:
X3T10:
A recommendation on the FDD standard 9315:1989 whether this ISO
standard represents the best possible solution at this time;
whether actual practice is consistent with the ISO standard; and
whether the ISO standard should be confirmed for another five
years, revised and if so why, or withdrawn with reasons; and
finally if it is to be revised whether or not we are prepared to
participate in the development of the revision.
The equivalent request concerning the SCSI standard 9316:1989.
Both of these requests have a JTC 1 TAG deadline of 4/25/94 to
line up with a JTC 1 deadline of 6/30/94.
With regard to the questions on SCSI 9316:1989 it should be
pointed out that SCSI-2 has been issued as DIS letter ballot 9316-1
closing 8/24/94. The JTC 1 TAG pushback date is not yet known
X3T11:
In a similar vein X3T11 is required to make the equivalent set
of recommendations on the Data processing - Description of
interface between process computing system and technical process
ISO 6548. The deadline is also 4/25/94. This one is a bit more
convoluted. Somewhat in deference to earlier sponsorship of this
standard by Germany, the X3T9 vote at the SC 25 level was to
reaffirm. However Germany voted to withdraw. The U.S. delegation
to the 1993 meeting was persuaded by their arguments and now
recommends that we support their 1993 position in our
recommendation to the JTC 1 TAG.
CD 14165-1 (FC-PH) has been distributed with closing date of
6/3/94. The X3 and SC 25 TAG pushback dates are not yet known.
Because FC-PH was bigger than ANSI cared to distribute as an
information copy, the CD was inadvertently distributed by the SC 25
Secretariat only through the table of contents of Rev 4.0.
Consequently the acting IR assisted the SC 25 Secretary by rushing
a copy Rev 4.0 for a second distribution. Of course it is not known
what ultimate confusion will result among other nations over this
surprising event.
CD 11518-6 HIPPI-SC Revision 2.6 dated 1/29/93 has been issued
with the same closing date of 6/3/94 and unknown push back dates as
have:
CD 11518-2 HIPPI-FP Revision 4.3 dated 1/29/93
CD 11518-3 HIPPI-LE Revision 3.4 dated 1/29/93
CD 9318-6 IPI enhanced PHY dated 1/4/93.
X3T12:
X3T12 is required to make an equivalent set of recommendations
on the disposition of ISO 9314-1:1989 FDDI PHY and 9314-2:1989 FDDI
MAC.
Like the CDs noted above CD 9314-13 FDDI CT-PICS Revision 3.4
dated 5/28/93 has been issued. The acting IR is recommending a
letter ballot position presenting the changes necessary to bring
the eventual DIS up to the dpANS Revision 3.4.
In addition CD 9314-8 FDDI MAC-2 Revision 5 dated 12/21/92 has
been issued with the same deadline and unknown pushback dates.
The miscellaneous liaison and other reports covered: N134
Disposition of comments to DTR 12075 "Planning and Installation
Guide for CPC to support ... Token Ring Stations; N135 Liaison
report to SC 6 concerning 2.048 Mb/s and PHY layers; N144
Disposition of DIS 9314-5 FDDI HRC comments; N149 Liaison from SC
27, IEC TC 46, SC 46A, 46C, 86A, 86B, and 86 C to JTC 1?SC 25;
N152 Draft Agenda SC 25/WG 4; N154 Disposition of comments DIS
9318-5 IPI-2 Tape with N 41(?); N155 Programme of Work Status; N158
Liaison from SC 25 to ITU TS WG XVIII/3 concerning 100 ohm and 120
ohm cables for ISDN primarry access; N159 Lision report to IEC/SC
46D concerning connector IEC 603-7 and LCL Testing; N160 Liaison
statement to IEC/SC 86B concerning FO Connectors; N161 Liaison to
IEC/SC 46A concerning Test Method for Transfer Impedance;
At an earlier meeting a forerunner of X3T10 voted to withdraw the ANS FDD
standard and replace it with the ISO version 9315:1989. 9315 is now due for
its five year review. Consequently, as acting IR, Gene Milligan moved that
X3T10 recommend the following answers to the four questions:
1) 9315:1989 FDD represents the best possible solution for
international application at this time.
2) Actual practice is consistent with 9315:1989 FDD.
3) X3T10 is in favor of confirmation of 9315:1989 FDD.
4) If the voting results in a need for revision of 9315:1989 FDD, X3T10
is prepared to participate in review and comment on proposed
revisions. However X3T10 is not likely to offer a project editor for
such a revision.
Steve Heil seconded the motion. The motion passed 34:0:0:25.
The forerunners of X3T10 and SC 25 have previously recommended that from a
planning standpoint the ISO SCSI standard 9316:1989 be replaced with the
eventual ISO SCSI-2 standard. Consequently, as acting IR, Gene Milligan move
that X3T10 recommend the following answers to the four questions:
1) 9316:1989 SCSI no longer represents the best possible solution for
international application.
2) Actual practice is no longer consistent with 9316:1989 SCSI. It has
been overtaken in a downward compatible manner by DIS 9316-1 SCSI-2.
3) X3T10 is in favor of withdrawal of 9316 upon publication of 9316-1
SCSI-2 for the reason noted in the answer to question 2.
4) If the voting results in a need for revision of 9316:1989 SCSI X3T10
is not prepared to participate in review and comment on a proposed
revisions and is not likely to offer a project editor for such a
revision.
Steve Heil seconded the motion. The motion passed 34:0:0:25.
Although the pushback date is not yet known and there could be time at a
later meeting, Gene Milligan saw no reason for deferring action on the SCSI-2
DIS. Consequently, as acting IR, Gene Milligan moved that X3T10 recommend
approval of DIS 9316-1 SCSI-2. Steve Heil seconded the motion. The motion
passed 34:0:0:25.
Based upon the ESDI discussions under New Business Items, as IR, Gene
Milligan moved that X3T10 instruct the IR that if the SC 25 Secretariat
determines that ISO/IEC 10 has not been published, the IR take steps to
discontinue publication of the standard. Dal Allan seconded the motion. The
motion was passed 34:0:0:25.
John requested that persons interested in attending the ISO SC-25 working
groups meetings beginning on July 4th in Denmark identify themselves. Gene
Milligan and Larry Lamers said that they would be attending. Gene said that
Roger Cummings indicated that he and Horst Truestead would volunteer from
X3T11.
12. Liaison Reports
12.1 X3T11 Liaison Report [Cummings]
94 people attended the February X3T11 Plenary.
Initial membership in X3T11 is 49 organizations.
FC-PH Second Public Review closed 2/15/94 with comments from X3T9.3
and IBM. Comment resolution is expected in 3/94.
FC-FP Revision 2.1 is in First Public Review, closing 5/21/94.
X3T11 Letter Ballots, closing 4/13/94, for forwarding for 1PR
for:
HIPPI-FP Amendment, Revision 1
FC-AL (Arbitrated Loop), Revision 4.2
FC-SB (Single Byte Command Code Sets), Revision 3.0
SD-3 for FC-GS (Generic Services) forwarded to X3.
Work on FC-EP starting in earnest:
First proposals for 2,4&8 gigabit variants
Additional copper variants (e.g. STP-5)
Bufferred Class 1 operation, data compression
Work on ATM mapping proposals also now underway.
12.2 SFF Industry Group [Allan]
Dal Allan requested that future agenda replace "Small Form Factor" be
replaced with SFF.
Dal reported on two connector decisions taken by SFF. SFF has a document
(SFF-8017) showing 26 tables of mix-and-match SCSI cabling. Dal recommends
obtaining a copy of mix-and-match document. Dal reported that the document
describing the unitized-parallel connector for rack applications will be
revised and distributed for letter ballot vote.
Sun Microystems has provided a copy of the SCA (Single Connector Attach)
without copyright for distribution as SFF-8015.
The BIOS and software limitations of drives >528 MB was renamed to be <=8GB
and a new revision will incorporate recommendations on the translation of CHS
defined by Identify Drive parameters.
The Unitized Parallel Connector SFF-8009 will be revised to add dimensions
so that the mating interface of the three connectors (68-pin P-cable, 12-pin
2mm Features, 4-pin Power) will have the same spacing between them.
12.3 IEEE P1394 [Marazas]
Jerry Marazas reported that the IEEE P1394 committee approved distribution
of a 30-day letter ballot to approve forwarding of P1394 to IEEE MSC for
public review. The IEEE MSC meets on May 9. If IEEE MCC approves, P1394
will be placed in public review. If no problems are identified during the
public review, P1394 will become an IEEE standard and the committee will
disolve.
12.4 IT8 [Lohmeyer]
No report.
12.5 IEEE P1285 Status [Pak]
Dennis Pak provided a written liaison report, which can be found in document
94-076. The committee accepted the report without comment.
12.6 PCMCIA Report
Larry Barnes described the history, problems, and current status of efforts
to put SCSI on PCMCIA cards. Larry noted several restrictions of SCSI on
PCMCIA. Larry noted that only single ended SCSI will work in this environ-
ment. Cable lengths will be 1.5 meters or less. Only three drops can be
supported.
Specific cable layout, connector issues, and termination issues produced
significant amounts of discussion. Several X3T10 representatives showed some
frustration regarding some of the PCMCIA choices, particularly regarding
connectors and termination. Also, several PCMCIA organizational practices
generated controversy.
Gene Milligan questioned whether placing the REQ and ACK signals in same
bundle was inviting crosstalk problems and wondered whether grouping REQ and
ACK separately with data signals would be better. Bob Snively responded that
Sun had experimented with such a cable grouping and had found that placing
REQ and ACK in the same bundle is superior. Consequently, there were no
specific recommendations regarding the cable.
The slides from Larry's presentation can be found in document 94-077.
12.7 AIIM C21 [Podio]
William Burr reported on ANSI/AIIM MS59-199x, a Media Error Monitoring and
Reporting Technique for Verification of Information Stored on Optical Digital
Data Disk. This work is of interest to organizations that store data for
long periods of time (e.g., the Library of Congress). The standard specifies
the methods for reporting reallocated sectors, corrections above a specified
threshold, number of errors, uncorrected data, and errors in header
information. The standard extends the definitions of the SCSI MODE SELECT
and INQUIRY commands. Vendor unique mode page and vital product data pages
have been defined. Requests were made for SCSI-3 mode page codes.
The committee members were not pleased with the use of mode pages. Log sense
pages were suggested as the correct place for error information reporting.
Specific details of the objections were presented. John recommended that
Fernando Podio contact Gary Stephens or Ralph Weber for guidance. John
further recommended that Fernando attend the May meetings in Harrisburg.
Steve Heil reported that ISO SC-23 and ISO SC-15 (technical committees in the
optical disk industry) have concerns regarding this work.
George Penokie moved that X3T10 notify Fernando Podio that unless he can
prevent ANSI/AIIM MS59-199x from moving forward, the Chairman of X3T10 will
forward a letter to AIIM and/or BSR stating that MS59-199x may have
unexpected and undesirable impact on the SCSI devices that have to support
the specified functions. Gary Stephens seconded the motion. The motion
passed 21:1:0:38. John took an action item to monitor AIIM activities in C21
and write the letter if necessary.
Chair's note: On 3/22/94, Fernando Podio contacted the chair to say that
C21 would hold up the draft standard until the issues can be resolved.
Bill's report can be found in document 94-083.
13. Review of Action Items
10) John Lohmeyer will contact Lynn Barra to resurrect the LOG SENSE TIB
(X3T9.2/90-165).
11) Larry Lamers will incorporate SCAM in SPI.
12) John Lohmeyer will write a letter accepting the SPI public review
comment regarding SCAM.
13) John Lohmeyer will inform X3 of the recommendation to reaffirm ESDI
(ANSI X3.170-1989).
14) John Lohmeyer will monitor AIIM activities in C21 (ANSI/AIIM MS59-199x)
and write the letter if necessary.
15) Bob Snively will investigate liaison with IEEE P1244.5.

Jul 18-22, 1994 Manchester, NH DEC
Sep 12-16, 1994 Houston, TX Compaq
Nov 7-11, 1994 Palm Springs, CA Western Digital
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 is automatically deferred to the plenary group.
Jeff Stai moved and Neil Wanamaker seconded that X3T10 authorize the X3T10-
related meetings and events in the list above. The motion passed
unanimously.
14.2 Authorization of 1995 Meeting Dates, Locations, and Hosts
John Lohmeyer presented a foil (summarized below) showing the proposed 1995
meeting dates, locations, and hosts.
The long-term X3T10 meeting week schedule is:
Date Location Host/Comments
--------------- ------------------------ --------------------------
Jan 8-13, 1995 Lake Tahoe, NV SSI
Mar 5-10, 1995 Newport Beach, CA QLogic
May 7-12, 1995 Harrisburg, PA AMP
Jul 9-14, 1995 Colorado Springs, CO NCR
Sep 10-15, 1995 Manchester, NH Digital
Nov 5-10, 1995 Southern CA Western Digital
Dal Allan moved that X3T10 accept the proposed 1995 meeting dates, locations
and hosts. Steve Finch seconded the motion. The motion passed 18:1:0.
14.3 Notification of Meeting Hosts Regarding Schedule Changes
Dal Allan moved:
1) that all committees provide the host with a firm meeting schedule
30 days prior to the actual meeting week.
2) that additional meeting requirements within the 30 day window be
arranged directly with the hotel, with the hotel, with the costs
born by the requesting organization, and not involving the host.
3) that cancelations must be made through the host, with the canceling
organization financially responsible for any cost incurred by the
host related to the cancelation.
Jeff Stai seconded. The motion passed unanimously.
