Opening Remarks John Lohmeyer, the Chairman, called the meeting to order at 9:00 a.m., Monday February 22, 1988. He thanked host, Duane Barney, of Honeywell Bull for arranging the meeting in such a warm, pleasant location. He also thanked Harlan Andrews and Apple Computer for making the January mailing. He reminded all attendees to promptly return their Document Distribution Application Forms to CBEMA so that they will receive the next committee mailing. John also stated that his phone number and the SCSI Bulletin Board phone number will change on Sunday, March 13, 1988. The new numbers will be: (316) 636-8703 for John and (316) 636-8700 for the SCSI BBS. As is customary, each of the attendees introduced themselves. A copy of the X3T9.2 membership list was circulated for attendance and corrections. Copies of the draft agenda, the recent document register, and information on X3T9.2 were made available to all attendees. 2. Approval of Agenda The draft agenda was approved with the following additions: 9.9 Management of "Grown Defect List" (X3T9.2/88-004) [Johansson] 9.10 Flexible Disk Standards. 10.3 Overview of X3B7.1 activities [Meijers] 10.4 Synchronized Spindles [Mortensen] 10.5 Autosense 3. Attendance and Membership Membership requirements were reviewed. The Chairman stated that two organizations had requested membership since the last meeting. Ray Calvin and Michael Kosmala are the Principal and Alternate from Hirose Electric U.S.A. Randy Lovelady and Irv Triner are the Principal and Alternate from Molex Inc. Donna Pope and Larry Stoner, the Principal and Alternate from Cipher/Optimem, have left that organization. The new Principal is Ishtiyaq Syed and the new Alternate is Beth Stephens. New members at the meeting were Jerry Amstutz of ACT/Shugart, Robert Kellert and Joe Chen of Cirrus Logic, Daniel Loski of PTI, David McFadden and H. Minawa of Honda Connectors, Daniel I. Amey and Bob Strich of Elco Corp., and David Hatch and Terry Meighen of Stewart Connector Systems. 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 stated that he had sent jeopardy letters to all representatives of the following organizations: Amphenol Corp.; Cipher/Optimem; Laserdrive; MAI Basic Four; NCL America; Pentax Teknologies; Priam Corp.; Prime Computer, Inc.; and Seagate Technology. The letters said that these organizations failed to attend two of the last three plenary meetings and that their membership would be terminated unless they attended the February plenary meeting. Representatives were present from all of these organizations except: Laserdrive; NCL America; and Pentax Teknologies. The unrepresented organizations were terminated (that is, changed to Observer status). 4. Approval of Minutes - Dec. Meeting San Diego (X3T9.2/87-200 Rev 2) The minutes, which were previously revised through comments on the SCSI Bulletin Board, were approved without further changes. 5. Document Distribution The following new documents were distributed at the meeting: Document Doc Date Author Description of Document ------------- -------- --------------- --------------------------------------- X3T9.2/87-19 2/19/88 R.

Snively Consideration of phase definitions X3T9.2/88-24 2/22/88 D. McIntyre Unimplemented Page Request Response 5.1 New Document Distribution Procedures The Chairman stated that the new document distribution system will be used for the next mailing. It is very important that committee members promptly return the subscription form to the X3 Secretariat at CBEMA with their payment. The X3 Secretariat will maintain the database of who gets the mailings. Any address changes, member changes, etc. should be sent to both the X3 Secretariat and to John Lohmeyer. 6. Liaison Reports 6.1 ISO Gene Milligan reported that the eight position recommendations from the last meeting have been transmitted to ISO. He stated that the revised Flexible Disk standard does not appear to include everything that he expected it to include, but what is there is acceptable. John Lohmeyer reported that Bill Burr is editing the ISO SCSI draft standard. A copy containing of sections 5 through 8 was available during the meeting for review and comment. 7. Review of Old Action Items 7.1 Larry Lamers will reword section 5 to clarify that the initiator cannot send multiple groups of messages during a single MESSAGE OUT phase. Unresolved, but may be resolved by the ad hoc group that is working on clarifying message handling. 7.2 Paul Boulay will review the archival vs. update issue for WORM optical media. Carried over. 7.3 Bob Snively will investigate compatibility issues of non-queued targets with queued initiators. Carried over. 7.4 Gary Stephens will propose revised wording in the retry counts and algorithms of REQUEST SENSE and MODE SELECT. Carried over. 7.5 John Lohmeyer will revise the SCSI-3 Project Proposal [87-193]. Complete. 8. Working Group and/or Project Status Reports 8.1 ESDI At its last meeting, X3T9 voted to include Appendix K on synchronized spindles into the ESDI document before it was sent to X3 for public review. Appendix K was included in the last X3T9.2 mailing. 8.2 SCSI General Working Group (X3T9.2/88-011) An SCSI-2 Working Group meeting was held January 6-8, 1988 in San Jose, CA with 27 attendees. Dal Allan chaired the meeting which was hosted by Adaptec and Quantum. The minutes were distributed in the January mailing (X3T9.2/88-011). Larry Lamers reported the highlights of the meeting. 8.2.1 SCSI-2 vs. SCSI-3 determination There was a discussion of X3T9.2/87-215 Rev 1 which proposes a process for determining which items will be considered under SCSI-2 and which will be deferred to SCSI-3. Items which are clearly clarifications or corrections would automatically be given first priority. New proposals which the author wants included in SCSI-2 would be given 5 minutes of plenary time to determine whether the majority of the membership favors adding the proposal to SCSI-2. If accepted, these items would be given second priority. Items proposed for SCSI-3 and those items failing to receive majority acceptance are third priority for committee attention. Bill Spence moved and Gene Milligan seconded that X3T9.2 adopt the principles set forth in X3T9.2/87-215 Rev 1 as a basis for accepting new proposals. The motion carried unanimously (28-0). 8.2.2 Working Group Recommendations A number of recommendations were made by the working group. Each of these recommendations were reviewed by the plenary with the following results: Fast SCSI (X3T9.2/87-195 Rev 3) was accepted for inclusion in SCSI-2 Rev 4. The working group asked the plenary to resolve whether the scanner command set should be restructured to use 2-byte length fields in the 10-byte commands and to add a 12-byte command set. Those in favor of this restructuring cited that it is inconsistent with the direct-access 10-byte commands which use 2-byte length fields. John Lohmeyer pointed out that the 6-byte commands for direct-access and sequential- access devices already have inconsistent length fields. A brief survey of those organizations who have implemented software drivers for multiple device-types, found no one who objected to the current inconsistency. The Chairman reminded the plenary that IT8 has established a liaison with X3T9.2 and expects to make some recommendations on this command set for SCSI-3. He recommended leaving the 12-byte command set for SCSI-3 in order to have maximum flexibility in dealing with the anticipated IT8 recommendations. Ben Driscoll moved that the scanner command set be accepted as is. Jim McGrath seconded and asked that the motion be modified to add that X3T9.2 investigate a 12-byte scanner command set for SCSI-3. Ben Driscoll agreed. The modified motion carried unanimously (35-0). Bob Snively's document on deferred error handling (X3T9.2/87- 019 Rev 1) was accepted for inclusion into SCSI-2 Rev 4. The working group reported that in spite of previous attempts to clarify this issue, target message handling is still confusing. There was a concern expressed that with the addition of several new messages, an initiator could string a long series of messages together in a single MESSAGE OUT phase. This would introduce complexity in the target's message handling due to the requirement that the target not switch phases while ATN is true except to send MESSAGE REJECT. This requirement is due to the method used to handle outbound message parity errors. One suggestion was that outbound message parity errors be handled with an inbound MESSAGE PARITY ERROR message. Several people objected to this change in that new devices would have to support both methods, further increasing complexity. (Chairman's note: This would also bring us back to the original outbound message parity error handling method that initiator designers found objectionable.) A small ad hoc group met on Monday evening to address this issue. On Tuesday, John Lohmeyer reported that the ad hoc group had agreed on a direction for solving the problem which should reduce message-handling complexity in both the target and the initiator. The approach would be to require the initiator to drop ATN on the last byte of several messages including those that require negotiation (synchronous and bus width) along with several others. Dexter Anderson agreed to prepare proposed wording. Jeff Stai's proposed modifications to the CHANGE DEFINITION and INQUIRY commands (X3T9.2/88-005) were discussed. CHANGE DEFINITION now has a DATA OUT phase to permit sending a password. This command no longer has a DATA IN phase. The information previously returned by CHANGE DEFINITION is now returned as "Vital Product Data" in the INQUIRY command. These modifications are to be included in SCSI-2 Rev 4 unless some objection is made at the next working group meeting. 9. Old Business 9.1 High-Density Connector Presentations/Discussion (3:00 p.m. Monday) The Chairman stated that he had sent a letter to nine connector vendors who had requested X3T9.2 mailing labels. In addition to the mailing labels he had enclosed copies of the ANSI patent policy, an extract from the December plenary minutes, and a request that each vendor provide a letter concerning their position regarding patents along with drawings suitable for inclusion in the draft standard. He stated that he had received a lot of information from the vendors and had spent many hours on the phone with them. Due to the large number of presentations planned, the Chairman requested that all presentations be limited to 10 minutes. He also proposed that one talk per proposal be given first followed by time for questions and answers. If time still remained additional talks would be permitted. Ten-minute presentations were made by the following people: 3M, ITT-Cannon, Dupont-Berg: John Knudsen Hirose, T&B, Molex: Ray Calvin, Mike Kosmala Elco: Don Amey Burndy: David Barnum, Jerry Marazas AMP, Fujitsu, Honda, Hirose: Ed Reynolds, Joel Urban, Dave McFadden Stewart, Viking: David Hatch, Karl Kwiat, Peter Kurbikoff JAE: Martin Pullman Don Amey indicated that Elco would support the 3M proposal. Thus the Elco proposal was dropped from consideration. Dal Allan prepared a "check list" of questions to aid in comparing the various proposals. This check list is attached as Enclosure (5). After the "question and answer" period, the Chairman offered time for the remaining presentations. The speakers declined due to the late hour and the less-than-enthusiastic audience. 9.2 High-Density Connector Selection (9:00 a.m. Tuesday) Before the voting began, Steve Goldman and Bob Snively gave a presentation on daisy-chaining issues. The presentation highlighted the issues of using flat ribbon cable to daisy-chain using high-density connectors. Most of the problems arise when mixing low-density and high-density connectors. There is also an issue of optimizing for 50-mil or 25-mil flat ribbon cable. Their presentation is attached as Enclosure (6). The Chairman stated that the voting process would be a successive elimination. Each member organization would be allowed to vote for one or more proposals on each round. The proposal receiving the fewest votes would be eliminated from the next round until only one proposal remained. The voting results were as follows: Round Proposal Style 1 2 3 4 5 6 --------------------------------- ----- -- -- -- -- -- -- 3M, ITT-Cannon, Dupont-Berg, Elco Rib 31 31 30 26 23 Hirose, T&B, Molex Rib 26 23 21 (Withdrawn by Elco) Rib Burndy Rib 12 10 Amp, Fujitsu, Honda, Hirose T&R 35 34 33 30 29 32 Stewart, Viking Tel 27 22 23 26 26 27 JAE T&R 01 TelTec Rib 00 Style Key: Rib Ribbon Style T&R Tab and Receptacle Style Tel Telephone Style After round 1, both proposal 7 and proposal 8 were eliminated due to the obvious lack of support for both of these proposals. There was no objection. Following the elimination voting, a brief break was taken while the Chairman prepared the following motion: Mr. Lohmeyer moved and Mr. Stai seconded that X3T9.2 accept the "tab & receptacle" style connector proposed by AMP, Fujitsu, and Honda for a 0.050-inch centerline connector as an alternative connector for high-density shielded and unshielded applications. Both 50-position and 68-position connectors are to be included for Cable A and Cable B, respectively. The cable connectors are to be male gender and the device/board connectors are to be female gender. The non-shielded connectors are to be included in the body of the document as an alternative to the current low-density connectors. The shielded connectors are to be included in the appendix as a third alternative to the existing two shielded connector alternatives. X3T9.2 requests that AMP provide the appropriate eight drawings to the document editors by March 7, 1988. The roll-call motion carried (48-7-0-13).

The motion carried unanimously (39-0). Gene Milligan moved and Dave McIntyre seconded that Gerry Houlder be assigned an action item to organize a special working group to develop a completed proposal on a single-cable, sixteen-bit wide connector for either SCSI-2 or SCSI-3 depending upon the acceptance and timing of his work progress (reference document 87-169 R2). The motion failed (3-28). 9.3 SEARCH Command Modifications (X3T9.2/88-002 - Jeff Stai) Since this item is related to the scatter write and gather read capabilities proposed for SCSI-3, it was put in queue for SCSI-3. 9.4 BUSY issue (short vs. long?) (X3T9.2/87-192 - Semenak) There was considerable discussion on when REQUEST SENSE data is valid. Some people were opposed to having REQUEST SENSE act differently depending on the previous status (BUSY vs. something else). Others suggested that "long" BUSY conditions should be avoided altogether by defining these as NOT READY. This issue also is related to extended contingent allegiance. Jim Semenak was requested to develop a NOT READY version of his proposal and this item was remanded to the working group for further work. 9.5 Review of SCSI-2 Draft Document (X3T9.2/86-109 Rev 3) There was insufficient time to review the draft document during the plenary meeting. This will be a high priority item for the next working group. 9.6 CD-ROM Proposals (X3T9.2/87-106 Rev 1 and X3T9.2/87-210 Rev 1) The new document (87-210 R1) combined previous documents from Sony and LMSI-OSI and is based on discussions between Paul Boulay and Larry Lamers. Unless there are objections at the working group meeting, this document will be incorporated into SCSI-2 R4. 9.7 Proposed SEND DIAGNOSTIC Pages (X3T9.2/87-186) [Spence] This item was moved to the SCSI-3 queue. 9.8 SCSI-3 Project Proposal (SD-3) (X3T9.2/87-193 Rev 1) Bob Snively moved and Dave McIntyre seconded that X3T9.2/87-193 Rev 1 be forwarded to X3T9 for further processing. The motion carried unanimously (39-0). 9.9 Management of "Grown Defect List" (X3T9.2/88-004) [Johansson] Peter Johansson expressed concern that his proposal (originally 87- 151) seems to have been forgotten. He missed a meeting where it was on the agenda and then it was dropped from subsequent agendas. John Lohmeyer suggested that it is the author's responsibility to keep track of his proposal. If it is dropped, final responsibility for keeping the proposal alive falls on its supporters. Lack of persistence may be interpreted as lack of support. It was noted that this proposal is not a trivial change and will require careful consideration. The proposal was remanded to working group with a high priority for consideration. 9.10 Flexible Disk Standards. Gene Milligan stated for the record that X3.80 does apply to flexible disk drives smaller than 5.25-inch form factor. It had been stated previously that X3.80 was lacking support for some 3.5- inch flexible disk drives. 10. New Business 10.1 Review of new documents Each of the new documents were briefly introduced and assigned a priority based on the mechanism proposed in 87-215 R1 (See 8.2.1). The items were then added to the working group agenda, below. 10.2 Agenda for Newport Beach Working Group The following agenda was drafted for the Newport Beach working group meeting. It consists of carry-over items from the last working group meeting plus new items recently submitted. Items are prioritized by SCSI-2 vs. SCSI-3 and by longevity. Agenda Items for SCSI-2 1. Grown Defect Management [87-151, 88-004] (Johansson) 2. [] bracket removal (sections 9 - 17) 3. Corrections to Deferred Errors [87-019R1] (Snively) 4. 3rd party RESERVE/RELEASE for copy management.

Expanded RelAdr Bit [88-007] (Boulay) 10.3 Overview of X3B7.1 activities [Meijers] Frank Meijers of Luctor gave a brief overview of the X3B7.1 activities on testing disk drives using an intelligent interface such as SCSI. Dave McIntyre moved and Bob Snively seconded that X3T9.2 request a liaison be established with X3B7.1 and that a report be given at the April plenary meeting. The motion failed (11-11). 10.4 Synchronized spindles [Mortensen] Bob Mortensen proposed adding an extension to MODE SELECT page 4 for controlling synchronized spindles. The physical layer would be similar to the ESDI approach, but Bob is principally interested in defining a mechanism to define who sources the sync signal. Of those voting in a straw poll, eight felt that this should be addressed in SCSI-2 and five felt this should be deferred to SCSI-3. This item was added to the working group agenda. 10.5 Autosense In discussing Dan Davies proposal (88-016), several people expressed concern that autosense adds unnecessary complexity. Jeff Stai moved and Skip Jones seconded that autosense be deleted from SCSI-2. The motion carried (18-2). As a result of this motion, 88-016 was removed from the working group agenda. 11. Review of Action Items 11.1 Larry Lamers will reword section 5 to clarify that the initiator cannot send multiple groups of messages during a single MESSAGE OUT phase. 11.2 Paul Boulay will review the archival vs. update issue for WORM optical media. 11.3 Bob Snively will investigate compatibility issues of non-queued targets with queued initiators. 11.4 Gary Stephens will propose revised wording in the retry counts and algorithms of REQUEST SENSE and MODE SELECT. 11.5 John Lohmeyer will take the SCSI-3 project proposal (X3T9.2/87-193 Rev 1) to X3T9. 11.6 Steve Goldman will research cables and pin assignments for new high-density connectors. 11.7 Charles Brill will provide the editors with the eight drawings needed for the high-density connector. 11.8 Larry Lamers will move bit 0 to bit 2 in the WRITE SAME CDB. Bit 0 will be reserved. 11.9 Dexter Anderson will develop proposed wording for resolving the message protocol issues. 12. Meeting Schedule The next meeting of X3T9.2 will be April 25-26, 1988 at the Trade Winds Hotel in St. Petersburg Beach, FL (800) 237-0707 or (813) 367-6461 hosted by AMP.
