- X3T9.2 Meeting #79 Minutes
- December 5-6, 1988 -- San Diego, CA
-
- 1. Opening Remarks
-
- John Lohmeyer, the Chairman, called the meeting to order at 9:00 a.m.,
- Monday December 5, 1988. He thanked Dan Davies of Cipher for hosting the
- meeting and he also thanked Classic Conferences for arranging the meeting.
-
- As is customary, the attendees introduced themselves. A copy of the X3T9.2
- membership list was circulated for attendance and corrections. Copies of
- the draft agenda and the recent document register were made available to all
- attendees. Information on X3T9.2 and Document Distribution Application
- forms were made available for new attendees.
-
- 2. Approval of Agenda
-
- The draft agenda was approved with the following additions:
-
- 6.3 SCSI-2 Common Access Method Committee Report
- 6.4 Fiber Channel
- 8.3.4 Generic Error Recovery Page
- 8.3.5 Save data pointer message
- 9.7 Terminate immediate (X3T9.2/88-158, -162)
- 11.2 New Device Type for SCSI-3 (X3T9.2/88-163)
-
- 3. Attendance and Membership
-
- The membership requirements were reviewed. The Chairman stated that since
- the last meeting several changes had occurred in the voting membership:
- Wayne Roen replaces Tony Kozlowski as the Principal for 3M. Chuck Kummeth
- was added as a second Alternate from 3M. John Herron has replaced Kim Le as
- the Aspen Peripherals Principal. Steve Brooks has been named the Cygnet
- Systems Alternate. Mark Sherwood replaces Ron Schlitzkus as the Alternate
- for Scientific Micro Systems. Honeywell Bull has become a member with Chris
- Kowal named as the principal.
-
- The following membership changes occurred during the meeting: Ken Post has
- replaced Lou Domshy as the Archive Principal. Lou is now at WangDAT.
- Curtis Ridgeway has replaced Fred Berkowitz as the Sun Microsystems
- Principal. Fred is now at Omni Solutions.
-
- Enclosure (1) is the list of attendees at the meeting. Enclosure (2) is the
- X3T9.2 membership changes since the last minutes and enclosure (3) is the
- current X3T9.2 membership list.
-
- 3.1 Roll Call of Members in Jeopardy
-
- The Chairman did not have time to send jeopardy letters, so there were no
- terminations due to non-attendance.
-
-
-
-
-
- 4. Approval of Minutes - October Meeting Boston, MA (X3T9.2/88-130 R1)
-
- The minutes were approved with the following correction:
-
- Delete the phrase, "but they would get hotter", from section 8.6, paragraph
- 3, second sentence. The revised minutes will be posted to the SCSI Bulletin
- Board, but not distributed in a mailing.
-
- 5. Document Distribution
-
- The last mailing was split into two parts. The first part (866 pages)
- included SCSI-2 revision 6 and was sent to most people via United Parcel
- Service. The second part (86 pages) went out after the Austin working group
- meeting and was sent to most people via first class mail.
-
- John Lohmeyer said that the X3 Secretariat had converted the mailing list
- from a word processor file to a data base and that as a result six or seven
- people were accidentally dropped from the subscription list. The error was
- corrected but these people did not get their mailings on time.
-
- Kate McMillan had informed John Lohmeyer that due to a mistake on postage,
- part 2 of the mailing was sent to the international recipients very late.
- Kate sent extra copies of part 2 of the mailing to John for those
- international attendees who did not receive their mailings prior to
- departing for the meeting.
-
- The job of maintaining the committee data bases has grown so large that
- CBEMA has hired a new employee to deal with this. Future inquiries
- concerning the committee data base or the subscription list should be
- directed to Andrew Barrera at (202) 737-8888.
-
- John Lohmeyer requested that all documents for the January mailing be sent
- to him before January 18, 1989.
-
- The following new or revised documents were distributed and/or discussed at
- the meeting:

-
- 6. Liaison Reports
-
-
- 6.1 ISO
-
- Chairman's Note: There was no report at the meeting due to a courier
- problem (i.e., I didn't receive the report until Thursday). Gene
- Milligan, who was unable to attend, did provide the following report:
-
- " The SMD interface standard was distributed as ISO/IEC DIS 9324
- under the fast track procedure. The draft was submitted 9/8/88
- and the voting terminates 3/8/89 (international dates were not
- used and without a priori knowledge they could be interpreted as
- 8/9/88 and 8/3/89).
-
- Unfortunately the second page attached to the distribution
- includes a cover note from the ITTF which X3T9 should recommend
- an objection to. The note in effect states that the SMD document
- does not comply with IEC/ISO Rules and will be amended if a
- favorable vote is received. It further states that the amendment
- project will be assigned to ISO/IEC JTC 1/SC 13. This
- complicates the recommendation X3T9 should make on this ballot.
- X3T9 should take action on this matter at the 9 December
- meeting.
-
- The second cover page also includes a synopsis of the fast track
- procedure.
-
- ISO/IEC JTC 1 N 317, dated 8 November 1988, provides
- significant comments from the voting on N 240 Directives for the
- Work of ISO/IEC Joint Technical Committee 1 (JTC 1) on
- Information Technology. The cover page optimistically describes
- the voting results as substantial support with considerable
- editing needs. While the U.S. submitted only a few trivial
- comments, the entire package includes 63 pages of comments.
- There are numerous comments of significance.
-
- We should be in agreement with many of the comments. There are
- two which we should consider for a possible recommendation to
- ANSI. The Danish comments include a recommendation for a
- procedure to require a fast track DIS preview by the responsible
- SC. The UK comments point out that the the directives do not
- include procedures for the case when a fast track document is
- not in compliance with ISO/IEC rules for presentation. The UK
- recommended that such procedures be added and that they state
- that the originator be responsible for redrafting, not the ITTF
- or any JTC 1 body.
-
- In addition to the action required during this week on the SMD,
- X3T9 should plan to have their submissions and recommendations
- ready for the September SC 13 meeting by the end of the April
- meeting. "
-
- 6.2 IT8
-
- Mr. William Smythe had sent a letter (X3T9.2/88-137) to John Lohmeyer
- requesting that X3T9.2 include a reference to IT8's project in SCSI-2.
- This project is to develop a standard on the exchange of digital data
- between color electronic prepress systems and direct digital color
- proofers. Although IT8 has selected SCSI-1 as the basis for their
- standard, they are requesting that the reference be included in SCSI-2 as
- an appendix. The Austin working group recommended that such a reference
- be included, but that the editors should choose the best place to include
- the reference. Possibilities include the foreword, Section 1, Section 2,
- or a new appendix.
-
- 6.3 SCSI-2 Common Access Method Committee Report
-
- Dal Allan reported on the first CAM meeting. Documents were distributed
- from Seagate on SCSI Access Method (SAM), from Columbia Data on Standard
- Device Level Protocol (SDLP), and from Cipher on SCSI-Facto. Iomega made
- a presentation on their implementation of a common access method. The
- next meeting is on Wednesday, December 7, 1988. Document X3T9.2/88-148
- contains the minutes from the first meeting. John Lohmeyer has setup a
- separate area on the SCSI Bulletin Board for CAM documents. Those
- documents that are available in electronic format will be placed in file
- area 13.
-
- 6.4 Fiber Channel
-
- Dal Allan reported on the most recent Fiber Channel working group meeting
- which was held December 1-2, 1988. The minutes of this meeting will be
- distributed as X3T9.2/88-160 in the next X3T9.2 mailing. Dal also stated
- that the other Fiber Channel working group documents will be distributed
- in the X3T9.3 mailings.
-
- The next meeting of the fiber channel working group will be held on
- January 30-31, 1988 at the Sunnyvale Hilton, in Sunnyvale, CA.
- Reservations for rooms ($89 per night) should be made under ENDL. There
- will be a $20 meeting fee to cover expenses.
-
- 7. Review of Old Action Items
-
- 1. Bob Mortensen will take another pass at the wording on Rotational
- Position Locking and will submit it to the working group for further
- consideration. Completed by Larry Lamers.
-
- 2. John Lohmeyer will revise section 5 to include 88-91 along with the
- modifications developed in the August meeting. Complete.
-
- 3. Gary Robinson will address the edge connector dimension issue in the
- Flexible Disk standard (X3.80R-198X). Completed by Chuck Brill.
-
- 4. Jim Semenak will correct page 7-31 paragraph 3 in SCSI-2 R5 which
- references a section that does not exist and should contain a
- description of time ordering of log entries. Carried over.
-
- 5. Jim Semenak will clarify the format-in-progress part of the sense-key
- specific bytes in the REQUEST SENSE data wording so that it is clear
- that it only applies to the FORMAT UNIT command with the Immediate bit
- set to one. Complete.
-
- 6. Christian Mollard will develop a complete proposal on changing the
- termination network for single-ended systems. Complete (88-142).
-
- 7. Dal Allan will revise the ESDI dpANS per the results of the ad hoc
- meeting (see 88-131) and he will forward master copies to John
- Lohmeyer for the X3T9.2 mailing and to Bill Burr for the X3T9 mailing.
- (See agenda item 8.1 -- reassigned to John Lohmeyer and Larry Lamers.)
-
- 8. Larry Lamers will contact Greg DeRosa concerning the development of a
- model and a glossary for scanner devices and his willingness to be the
- scanner section editor. Carried over.
-
- 9. John Lohmeyer will obtain Bill Burr's model on rotating mass storage
- devices for possible use in developing the SCSI-2 model for direct-
- access devices. Complete (88-139).
-
- 8. Working Group and/or Project Status Reports
-
- 8.1 ESDI
-
- Dal Allan reported on the status of ESDI. He had edited the public
- review changes into the ISO version of ESDI and did not update ESDI
- version 2.A, which was the public review document. He then sent this
- document electronically to John Lohmeyer. Dal stated that his impression
- is that all documents should be edited to ISO format. He felt that there
- is no technical justification for a difference in format between ANSI and
- ISO. Since ISO will not print an ANSI style document, we should use the
- ISO style, which ANSI may accept. At this time there is no definitive
- decision from ANSI, but Dal expects one in the near future. Dal
- indicated that he would not maintain the ANSI version of ESDI.
-
- Dal has converted all of the documents for which he is the editor to ISO
- style. Dal stated that the revised ISO ESDI is not technically different
- from the ANSI ESDI 2.A document plus the Boston changes. Only the style
- has changed and most of these editorial changes are confined to the first
- 4 sections.
-
- John Lohmeyer stated that he had initially agreed to print the document
- for the mailing, but had not included it because he did not have the
- figures to paste into the document nor did he not have time to act as the
- ESDI editor. He also had concerns that the style change would not be
- acceptable to the committee. He outlined two paths: accept Dal's ISO
- version and distribute it, or find a new editor to maintain and revise
- the ANSI ESDI document.
-
- The committee decided to distribute the ISO-style document in the January
- mailing. John Lohmeyer and Larry Lamers will do the necessary editing to
- get this document into the January mailing. John Lohmeyer advised the
- members to allocate adequate time in early February to review the
- document carefully as a forwarding motion is planned for the February
- meeting.
-
- John Lohmeyer stated that Bret Weber had reviewed the new document and
- Bret had a problem with the trigger condition for requiring that the ESDI
- drive report its transfer rate. The Boston ad hoc group had agreed that
- any drive which supports subscripting must report its transfer rate. The
- document says that any drive that implements the high-speed port option
- must report its transfer rate. This problem should be corrected before
- the mailing.
-
- 8.2 Flexible Disk
-
- This document was distributed in the X3T9 mailing. Unfortunately, the
- copy John Lohmeyer received lacked sufficient quality to be photocopied
- for the X3T9.2 distribution. Anyone who really needs a copy should
- contact John.
-
- 8.3 SCSI General Working Group (X3T9.2/88-153)
-
- Bill Spence hosted a working group meeting in Austin, Texas on November
- 7-9, 1988 with 30 attendees. The principal work done at this meeting was
- to review SCSI-2 revision 6, which Bill generously copied for the
- attendees. The working group made a large number of recommendations to
- the plenary group plus three topics that require plenary discussion. The
- recommendations were all highlighted in the working group minutes with
- bold type.
-
- Dal Allan reviewed the recommendations in the working group meeting
- minutes with the following results:
-
- Deletion of the EXTENDED IDENTIFY Message -- Accepted.
-
- The recommendation to exclude the READ LONG command from CD-ROM
- devices was rejected. Paul Boulay will add this command to the CD-ROM
- command set.
-
- Add the WRITE SAME command to section 15, but not 9 -- Accepted.
-
- The CHANGE DEFINITION command should not be changed -- Accepted.
-
- The Rotational Position Locking recommendations were accepted, except
- clarification is needed on when unit attention conditions are created.
- These unit attention conditions should occur when sychronization
- status changes.
-
- The recommendations in item 1.6 of 88-153 concerning section 9 were
- accepted, except Paul Boulay was assigned to write the implementors
- note on restoring mode parameters following a third-party release.
-
- The working group recommendations concerning 88-146 were accepted.
-
- The working group recommendations concerning medium changers were
- accepted.
-
- The working group recommendations concerning the appendixes were
- accepted.
-
- Bill Spence moved and Paul Nitza seconded that the working group
- recommendations as modified above be accepted, but that soft reset, save
- data pointer, generic error recovery, rotational position locking, and B
- cable detect need further discussion to arrive at a consensus. The
- motion carried unanimously.
-
- 8.3.1 Delete soft RESET Alternative?
-
- Paul Boulay moved and Gary Stephens seconded that the soft RESET
- alternative be retained and a bit be added to the INQUIRY data to
- indicate that soft RESET alternative is enabled. The motion carried
- 27 to 6.
-
- The SftRe bit will be added to byte 7, bit 0 of the INQUIRY data with
- the following wording:
-
- "A soft reset enabled (SftRe) bit of zero indicates that the target
- responds to the RESET condition with the hard RESET alternative. A
- SftRe bit of one indicates that the target responds to the RESET
- condition with the soft RESET alternative."
-
- 8.3.2 B Cable detection scheme (X3T9.2/88-156)
-
- Tom Wicklund had suggested in 88-114 that a detection scheme be
- devised to detect the presence or absence of the B cable. The working
- group discussed several methods and selected one that they assigned to
- John Lohmeyer to document. John found a significant problem with the
- selected technique and opted to document another technique that had
- also been discussed by the working group.
-
- There was a discussion of whether this function is needed at all and,
- if so, whether other methods of detection (time-outs on REQB or ACKB
- or both) might not be more desirable.
-
- Steve Cornaby moved and Steve Goldman seconded that X3T9.2 not add a B
- cable detection protocol to SCSI-2. The motion carried 21 to 12.
-
- 8.3.3 Wide data transfer bit ordering
-
- While the bit ordering is not especially intuitive, it was deemed
- acceptable. The only real concern was that people may assume a
- different ordering because of the way bits are numbered.
-
- It was noted that some text in section 4 concerning the wide DATA BUS
- may conflict with the text in section 5. Jeff Stai presented a new
- figure (see below) that may help clarify the byte ordering when using
- 8-, 16- or 32-bit wide buses. John Lohmeyer will correct the wording
- in section 4, delete the [] note in section 5 and include Jeff's
- figure.
-
- When transferring bytes W, X, Y and Z across various bus widths, they
- are transferred as follows:
-
- Hand- 8-bit 16-bit 32-bit
- shake ______ ______
- # A Cable B Cable A Cable / B Cable \ A Cable
- +-------+ +---------------+ +-------------------------------+
- 1 | W | | X | W | | Z | Y | X | W |
- |-------| |-------|-------| +-------------------------------+
- 2 | X | | Z | Y | 31...24 23...16 15....8 7.....0
- |-------| +---------------+ Bit Number
- 3 | Y | 15.....8 7.....0
- |-------| Bit Number
- 4 | Z |
- +-------+
- 7.....0
- Bit
- Number
-
- NOTE: This figure does not represent how these bytes are stored in
- the initiator's memory, which may be different.
-
- 8.3.4 Generic Error Recovery Page
-
- Dan Davies had previously proposed that the mode page on error
- recovery be made generic across all device types. During the
- discussion, it became apparent that neutering the information in this
- page so that it could be generic would require that sections be added
- to each device type clarifying how the generic error recovery applied
- to that device type. This would largely wipe out the paper savings
- that Dan was attempting to achieve.
-
- Jeff Stai moved and Jim Semenak seconded that X3T9.2/88-103R2
- (proposing a generic error recovery page) be rejected. The motion
- carried 23 to 6.
-
- 8.3.5 Save data pointer message
-
- This subject had been discussed at the previous plenary meeting (near
- the end of the meeting) and at the Austin working group meeting.
- Related documents are 88-120, 88-152, and 88-153. The main issue was
- whether the target should be required to insure that the final value
- of the current data point reflect the actual transfer length. At
- Boston, the plenary decided that the target should be required to do
- so. The Austin working group felt that this requirement was too
- strong and recommended that the requirement depend on a new mode bit
- called the Save Data Pointer Control (SDPC) bit.
-
- Several people were confused in that the proposal was concerned with
- the current data pointer and not the saved data pointer. While many
- (but not all) host adapters make the final value of the saved data
- pointer available to software, very few make the final value of the
- current data pointer available.
-
- The proposal was aimed to solve the problem of one host adapter that
- verifies the actual data transfer length by inspecting the final value
- of the current data pointer.
-
- John Lohmeyer moved and Bill Spence seconded that the two underscored
- paragraphs on page 5-29 (S2R6) be deleted and that the SDPC bit not be
- accepted. The motion carried 20 to 4.
-
- 8.4 Fiber Optic Physical Layer Working Group
-
- Dal Allan reported on the Fiber Channel working group meeting that was
- held December 1-2, 1988 in Cupertino. This group is actively solicting
- proposals at this time. Dal also requested that people who have a
- background in SCSI attend these meetings to insure that the Fiber Channel
- does not neglect SCSI. See document X3T9.2/88-160 for additional
- information of the Fiber Channel project.
-
- 8.6 Transmission Line SSWG
-
- The Austin working group recommendations on this topic were accepted.
-
- 8.7 Medium Changers SSWG
-
- Paul Boulay reported that the revised medium changer section was well
- received in Austin. He has had requests from several people to include
- the ability to deal with volume tags. He plans to incorporate this
- feature in the next revision of the medium changer section.
-
- 9. Old Business
-
- 9.1 Proposed change to the Single-ended terminator
- (X3T9.2/88-142, -144, -161)
- Paul Boulay presented several overheads showing an analysis of Christian
- Mollard's proposal for termination. The worst case is termination at
- each end with terminator power supplied in the middle of the cable.
- Using 180/390 raises the setpoint in marginal conditions and lowers the
- impedance to about 123 ohms. The consensus was that much of this
- information is beneficial to users and should be included in an appendix.
- Paul Boulay accepted an action item to develop this appendix. 88-161 was
- accepted for inclusion in SCSI-2.
-
- It was proposed that 88-161, which contains the essential requirements
- for single-ended terminators, be included in SCSI-2. This document would
- still permit the 220/330 ohm termination or one that meets requirements
- outlined in the document. Bob Snively objected that not having specific
- schematics could cause problems in sourcing cost-effective terminator
- assemblies.
-
- Bill Spence moved and Paul Boulay seconded that 88-161 be included in
- SCSI-2 Rev 7. The motion carried 23 to 7.
-
- During the above discussion, Dal Allan pointed out that the SCSI-2
- document fails to place any characteristic impedance requirements on
- round cables. John Lohmeyer said that this is probably an oversight and
- the group agreed to revise this section so that the characteristic
- impedance requirements in section 4.2 apply to all cable types.
-
- 9.2 Schedule for SCSI-2
-
- The editors plan to prepare a revision 6A, of just the sections which
- have substantially changed, for the Costa Mesa working group.
- Furthermore the editors plan to prepare a revision 7 for inclusion in the
- next mailing. A forwarding motion is planned for the February meeting.
-
- 9.3 Review of SCSI-2 Draft Document (X3T9.2/86-109 Rev 6)
-
- This item was deferred to the end of the meeting and then was dropped due
- to the late hour.
-
- 9.4 Cable Impedance Testing (X3T9.2/88-154)
-
- John Morse gave a report on the testing of new connectors and cables. He
- expects the testing to be completed for the February meeting. Kurt Chan
- stated he expects to have some results by the January working group
- meeting.
-
- Harvey Waltersdorf of Thomas and Betts gave a presentation of results on
- impedance testing of 50-mil center cable and made a recommendation that
- .050-inch spacers be used when folding cables for maintaining high
- impedance.
-
- Jeff Stai accepted an action item to develop a set of recommendations for
- proper cabling installations.
-
- 9.5 WDTR disable residue function (X3T9.2/88-116)
-
- After some discussion, Jeff Stai withdrew his proposal.
-
- 9.6 Power-on to selection time (X3T9.2/88-145 R1)
-
- The need for a definition of this time has been discussed on several
- occasions in the past. Joe Lawlor brought it up again at the November
- working group meeting. Jim McGrath recently identified this interval as
- requiring definition so that auto configuration can be implemented in
- SCSI-3 (88-115). The difficulty in achieving consensus has been on the
- value of the time interval. Systems integrators usually have favored a
- smaller number than the peripheral suppliers have been willing to accept.
- Also, a definition of what constitutes a response to selection is
- required.
-
- Jim McGrath was unable to attend this part of the meeting, but he left a
- document describing his opinion on the subject (88-159). Dal Allan read
- this document to the group.
-
- The 88-145R1 document was revised to read as follows:
-
- "Each SCSI device, as it is powered on, should perform appropriate
- internal reset operations and internal test operations. It is
- recommended that following a ten second period of delay after power on
- each SCSI target be able to respond with appropriate status and sense
- data to TEST UNIT READY, INQUIRY and REQUEST SENSE commands."
-
- Joe Lawlor moved and Dal Allan seconded that X3T9.2/88-145R1 paragraph
- two, as revised, be accepted for SCSI-2. The motion carried 32 to 6.
-
- A similar revision was made to the section of the document concerning the
- reset to selection time:
-
- "It is recommended that following a 250 ms period of delay after a hard
- reset condition each SCSI target be able to respond with appropriate
- status and sense data to TEST UNIT READY, INQUIRY and REQUEST SENSE
- commands."
-
- Bob Snively moved and Jeff Stai seconded that X3T9.2/88-145R1 paragraph
- four as revised, be accepted for SCSI-2. The motion carried 24 to 9.
-
- 9.7 Terminate Immediate (X3T9.2/88-158, -162)
-
- Steve Goldman's proposal was discussed and once again Jim McGrath's
- absentia comments were read by Dal Allan. The discussion appeared to be
- converging on including a TERMINATE IMMEDIATE message, but returning the
- residual block count in the REQUEST SENSE data instead of defining a new
- message for this function.
-
- Jeff Stai moved and Robert Kellert seconded that the terminate immediate
- function be moved to a SCSI-3 Specific-Subject Working Group (SSWG) so
- that it can be fully studied and developed. The motion carried 19 to 13.
-
- 10. New Business
-
- 10.1 Review of new documents
-
- Only a few new or revised documents were distributed at the meeting. All
- of these documents were discussed under other agenda items.
-
- 10.2 Agenda for the Costa Mesa Working Group
-
- The following draft agenda was established for the Costa Mesa working
- group meeting:
-
- 1. Review of SCSI-2 revision 6A.
- 2. Review of Jim Semenak's LOG SELECT/SENSE clarifications.
- 3. Preliminary report on cable/connector testing.
-
- While it is not expected, if time permits, the group will begin
- discussion on the SCSI-3 proposals:
-
- 50. 87-186 SEND DIAGNOSTIC Pages [Bill Spence]
- 51. 87-203 & 87-217 LOAD SKIP MASK command proposal [Greg Floryance,
- Dave McIntyre]
- 52. 87-206 More that 8 devices on wide SCSI [David Harms]
- 53. 88-002 Search Command modifications [Jeff Stai]
- 54. 88-007 Expanded RelAdr Bit Definition [Paul Boulay]
- 55. 88-69R1, 88-92, & 88-100 Autoconfiguration SSWG [Jerry Marazas, Paul
- Nitza, Jim McGrath, Paul Boulay]
- 56. 88-127 Error Handling Action Codes [George Penokie]
- 57. 88-158 TERMINATE IMMEDIATE message [Steve Goldman]
-
- 10.3 Cinch comments on unshielded connector figure 4-4 (X3T9.2/88-157)
-
- This comment resulted from confusion over the notes concerning the
- backend of the connector. While the figure is correct, it could benefit
- from some enlightened revisionist editorialization.
-
- 11. SCSI-3 Activities
-
- There was no activity on the SCSI-3 project since the last meeting. At this
- meeting a SSWG for terminate immediate was established.
-
- Chairman's note: While not reported at the meeting, the project proposal
- for SCSI-3 has been approved by X3.
-
- 11.1 Autoconfiguration SSWG
-
- There was no report.
-
- 11.2 New Device Type for SCSI-3 (X3T9.2/88-163)
-
- Matt Gulick of Apple Computer stated that there are features in DAT
- devices which are not fully exploited in the sequential-access device
- model. He is proposing that a new device type for DAT devices be
- included in SCSI-3. The question was raised as to whether we should
- remove the set mark feature from SCSI-2 in that it was added for DAT
- devices. It was felt that this feature could be useful for other types
- of sequential-access devices so it was retained.
-
- 12. Review of Action Items
-
- 1. Jim Semenak will correct page 7-31 paragraph 3 in SCSI-2 R5 which
- references a section that does not exist and should contain a
- description of time ordering of log entries.
-
- 2. John Lohmeyer and Larry Lamers will revise the ISO ESDI document to
- correct the cover page, to include the figures, and to correct the
- statement concerning transfer rate reporting requirements.
-
-
-
- 3. John Lohmeyer will correct the wording concerning byte ordering in
- section 4, delete the [] note in section 5 and include Jeff Stai's
- figure.
-
- 4. Paul Boulay will develop an appendix on single-ended terminators.
-
- 5. Paul Boulay will add the READ LONG command to the CD-ROM command set.
-
- 6. Paul Boulay will write an implementors note on restoring mode
- parameters following a third-party release.
-
- 7. Jeff Stai will develop cabling recommendations.
-
- 8. Jeff Stai will add the WRITE SAME command to section 15.
-
