Adjournment 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: Document Doc Date Author Description of Document ------------- -------- --------------- --------------------------------------- X3T9.2/88-103 D.

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. 13. Meeting Schedule The next meeting of X3T9.2 will be February 20-21, 1989 at the Windham Southpark Hotel (512-448-2222) in Austin, Texas hosted by Motorola.
