Opening Remarks John Lohmeyer, the Chairman, called the meeting to order at 9:00 am, Monday June 22, 1987. Each of the attendees introduced themselves and stated their company affiliation. The attendance list was circulated with the standard instructions on membership. The 1988 service fees for principals and alternates has been increased from $175 to $200 and from $100 to $150 for observers. The Chairman pointed out that X3T9.2 receives none of this money for its operation -- it goes for the support of the X3 Secretariat's office within CBEMA. X3T9 is planning to conduct an experiment in 1988 by charging still higher fees that would go to support X3T9.2 operation (copying and mailing expenses) The amount of the higher fees and the details of operation have not been decided. 2. Approval of the Agenda The agenda from the mailing was revised slightly and copies of the revised agenda were available at the meeting. A discussion of whether T9.2 and T9.3 could remain in a joint session for the whole meeting revealed that T9.3 planned to review the IPI-2 Tape document. A separate suite was arranged for this meeting, with Dal Allan chairing the session. Items 10.7, Microcode Downloading (X3T9.2/87-7 Rev 2) and 11.7, Review of New Documents, were added to the agenda. The agenda approved with these changes. 3. Attendance and Membership New members at the meeting were: Name Status Organization ----------------------- ------ --------------------------- Mr. Alan Ebright P Laserdrive Mr. Doug Mitchell A Laserdrive Ltd. Mr. Frank Krulc P NCL America Mr. Aki Komatzuzaki A NCL America Mr. Fred Berkowitz P Sun Microsystems, Inc. Mr. Paul Rikkonen A Sun Microsystems, Inc. The chair stated the attendance rules. No letters concerning non-attendance were sent since the last meeting (due to the meeting location and the Chair's lack of time), so there were no members "terminated" at the meeting. Enclosures (1) and (2) are the list of attendees for X3T9.2 and X3T9.3, respectively. There were a total of 70 attendees, 51 for T9.2, 9 for T9.3, and 10 for both meetings. Enclosure (3) is the changes to the X3T9.2 membership list. Enclosure (4) is the current X3T9.2 membership list. 4. Approval of San Jose meeting minutes (X3T9.2/87-71). The minutes were approved with no changes. The Chair noted that as a general rule minor changes to minutes will be reported in the minutes of the meeting that makes the changes, but the revised minutes will not be redistributed. Revised minutes will be placed on the SCSI Bulletin Board. 5.0 Liaison Reports 5.1 IEEE P996 - No report. 5.2 IEEE P1134 - Members who sent a diskette to Carl Warren received the first draft of the bios proposal document on the diskette. 5.4 ISO - Dal Allan reported that a mailing concerning the TC- 97/SC-13 meeting has been made, perhaps just to the editors. 6.0 Joint Working Groups 6.1 SCSI-2/IPI Differential Results of the test at National on the Madison Cable indicate 10 - 12.5 MHz may be possible on SCSI and IPI. The standard timings may have to change and the cable quality will have to be specified. Changing to ECL components may not be necessary. Fairchild is to report on their findings beyond 12Mhz at the next Working Group meeting. The SCSI tests were run at 50 meters. It was reported by Dal Allan that current-mode parts such as the 75108 and 75112 do not work correctly for this application. He stated that the IBM current-mode parts do work. Ed Caulkins will check on the IBM position concerning availability of these parts. Most of the work focused on voltage-mode RS-485 parts. The working group plans to prepare a report on their studies. John Lohmeyer stated that he is working on a timing model for SCSI arbitration. The model attempts to derive the SCSI arbitration timing parameters from the fundamental parameters (cable length, clock period, driver/receiver propagation delays). The purpose is to analyze proposed changes to SCSI. The model requires VP-Planner, or Lotus 123. He invited interested parties to examine the model for accuracy. He noted that while the current model does produce the SCSI arbitration timing values, he is aware of an error that suggests that our current numbers may need to be revised slightly. 6.2 High Speed Channel (HSC) The next HSC working group will be held on July 16-17 at Fairchild, 10400 Ridgeview Court Cupertino. Call Gary Murdock at (415) 864-6200 for details. No hotel arrangements have been made. The first half day will be devoted to high-speed differential issues. Copies of the minutes of the last meeting are available from Jay Ullal at (408) 732-2400. The document will not be available on the SCSI BBS due to its high content of graphical data. Don Tolmie is maintaining the mail list. Dal Allan called for a volunteer to be the secretary of this group. HSC has the following characteristics: 50 MByte/Sec modular increments in data rate (50, 100, 200, etc. MByte/Sec). The interface is being designed with a focus on eventual conversion to fiber optics, current requirements are for copper. 6.3 ESDI Rev 1.3 was distributed to the X3T9.3 membership. ESDI tape has been removed from the document, since there is not much interest in such devices. Also, ESDI tape is not architecurally consistent with ESDI disk. Only magnetic and optical disk are in current proposal. Gene Milligan moved that X3T9.3 accept X3T9/87-005 Rev 1.3 as the committee's working document for the ESDI project. Dan Banerje seconded the motion. The motion carried unamimously. Dal Allan proposed that X3T9.2 also distribute ESDI in the next mailing. The ESDI document should be reviewed carefully because a forwarding motion is intended at the next plenary meeting. The ESDI document will be available on the SCSI BBS with a separate message area (#16) setup for it. Copies on floppy disks are available from Dal Allan. A proposed recommendation from Jim Whitworth to include a command to permit setting sector sizes of greater than 4095 was accepted. 6.4 SMD & FLEX Final Edit Review - No report 7.0 Document Distribution The document register has a new field called "Resolution", which has the status of the document in the Chairman's viewpoint. If any discrepancy exists please notify the Chair. The revised document register was distributed at the meeting. Enclosure (4) is the current document register. The following documents were distributed at the meeting: Document Doc Date Author Description of Document ------------- -------- --------------- ---------------------------------------- X3T9.2/87-7 6/22/87 D. W. Spence Revised proposal for downloading Rev 2 microcode. X3T9.2/87-59 6/16/87 Queuing W.G. Command Queuing proposal for SCSI-2 (rev Rev 2 from 87-46, -49, 54) X3T9.2/87-76 6/18/87 P.

Davies Clarification of Additional Sense Codes for BLANK CHECK X3T9.2/87-98 6/22/87 D. Davies Proposed Buffered Mode for Deferred Error Handling Copies of documents 92, 93, 95, and 96 from Gary Stephens were not available at the meeting. Electronic copies will be placed on the SCSI BBS and these documents will be included in the next mailing. Gary Robinson commented that possible variations for document distribution should be considered since X3 may not go along with the X3T9 proposal that is before X3. Typical mailing costs are running in the thousands of dollars. The fee may range from $100 to $350 per year, with a target of $300. Typical postage costs are $2.40 for under 2 pounds. Frequently, our mailings exceed this weight. If the X3T9 proposal is not accepted at X3, then we must either get more volunteers or find a third-party organization to collect the money and make the mailings. 8.0 Review of Old Action Items 8.1 Gary Stephens will make a proposal to enumerate those MODE SELECT actions which will cause UNIT ATTENTION for Sequential-Access Devices. Complete. (X3T9.2/87-95) 8.2 John Lohmeyer will send a single-sided copy of SCSI-2 Rev 1 to Tony Lo for distribution. Complete. 8.3 Tony Lo will distribute SCSI-2 Rev 1 to the non-attending Principals and Alternates. Complete. 8.4 Jim Murphy will host a Scanner ad-hoc meeting April 29 at Dest. Complete (No report at the meeting). 8.5 Balu Balakrishnan will host a differential ad-hoc meeting May 14-15 at National Semiconductor. Complete (No report at the meeting). 8.6 Gerry Houlder will host a general working group meeting May 18-20 at the Airport Hyatt in Minneapolis. Complete. 8.7 Paul Nitza will prepare a proposal on INQUIRY 7Fh usage. Complete. X3T9.2/87-77 and X3T9.2/87-77 rev 1 8.8 Jim Semenak will include X3T9.2/87-68 (new density codes) in the next revision of section 9. Complete. 9.0 Working Group Reports 9.1 SCSI General See X3T9.2/87-80. The section 8 review was partially completed, but significant work remains to be done at next working group. John Lohmeyer has started the July working group agenda. Twenty items are carried forward. Tape Glossary Issue - comment from Bill Spence. There is a key problem, 1/2 inch tape uses EOT for what 1/4 inch tape calls early warning. Bill proposes to adopt the 1/4 inch standard using EOM and EOT. This issue needs to be revisited to develop a bridge in terminology between documents. Some changes in the documents could result. Bill was assigned an action item to work on the tape glossary. 9.2 SCSI Scanner - no report. 9.3 SCSI Queuing See X3T9.2/87-59 rev 2. Several concerns surfaced in Minneapolis. Four people subsequently met with Bob Snively to review those concerns. There is a proposed change to the messages for queuing. Several of the messages had their definitions enhanced. Two concerns: 1) The order in which the modifying tags are given (There is a preferance for the tag to come before the command, but it could come after). 2) Data integrity; how much responsibility does the O/S vs the controller have to insure the data integrity on the medium? The general feeling is that it is a software function. Restrictive protocols only solve some particular cases but still do not insure it, and there is an increased burden on the controller that may affect performance and may prevent other system solutions. The IPI queuing model should influence the SCSI queuing model so that they are similar. See action item 12.2. 9.4 SCSI Changers See X3T9.2/87-74. The base document has been prepared, however there is still much to do. Two changer models presented by S. Jones. The element address correlation to the SCSI ID appears ambigous and may need more work. There was more discussion on the architectural concepts of changers. The real issue is whether a more "logical level" command set makes sense. This item is on the July working group agenda. 9.5 IPI/High Speed Channel Don Tolmie brought a revision of his previous proposal. It was referred to the HSC Ad hoc meeting July 16-17. Bob Bellino sent a letter to Dal Allan expressing his pleasure at the results of the driver/receiver testing on the samples of his current cable. Bob has volunteered to build a pilot run of 5,000 feet if sufficient companies express an interest in purchasing it (to justify the cost of a special run). 9.6 IPI-2 Tape The document was reviewed and several comments on operation in Master-Slave-Facility configuration were made. Some, but not all of these were answered during the meeting, and others will require more work on the part of the editor. 9.7 IPI Communications Chuck Pheterson has responded to many of the comments made by X3T9 and brought one copy to the meeting for interested parties to comment on. He expects to have a completed document that can be ready for forwarding again before the end of the year. 9.8 IPI-3 Disk/Tape Rev 5A - No actions. 9.9 IPI-2 Disk Jim Luttrull submitted a proposal with a list of items which are either incorrect (editorial) in the standard and asked for clarification on some others so that there would be consistency in implementations where the standard does not specifically state what action to take. He also included material related to RPS extensions which complements the text of the standard and is suitable for inclusion as an appendix. A problem to be faced is that now the standards are published and the only revision activity is on the Physical Interface, there has to be some way to advise the world of changes, enhancements, corrections that are being made. The committee will establish a mechanism for addendums to be carried which can be used as the basis for an Errata to be provided by ANSI (and avoid having to wait until there is another revision of the standard). 10. Old Business 10.1 Review of SCSI-2 section 8 -- Remanded to working group. 10.2 Asynchronous Event Notification (AEN) - X3T9.2/87-52&-61. Paul Nitza, Gary Stephens, and Bob Snively had an extended discussion of AEN and deferred errors. Treatment of deferred errors needs to be specified (see X3T9.2/87-19). Paul Nitza suggested that the LUN 0 should always exist for processor devices, and other LUNs may exist according to the rules in 6.5.2. Gary Stephens suggested that the SEND Command should have a bit that indicates the data that follows is in the format of REQUEST SENSE data. More work is needed to clarify that AEN is optional. Bob Snively accepted an action item to generate rev 1 for next working group. 10.3 REQUEST SENSE Response Identification - X3T9.2/87-60. Paul Boulay's need for REQUEST SENSE data formats to deal with SCSI/CCS/SCSI-2 mixed command sets still needs to be dealt with. Greg Floryance would rather not support a separate command to switch between SCSI versions due to the limitations on ROM-based code. Bob Snively will undertake an action item to make a proposal on SCSI version switching. 10.4 SCSI-2 BROADCAST CAPABILITIY X3T9.2/87-61. Lou Edwards reported that Paul Boulay has decided not to pursue this proposal at this time in light of the changes it may require in existing protocol chips. 10.5 READ LOG COMMAND X359.2/87-43 Rev 1. Greg Floryance has revised this document to deal with the suggestions made at the last meeting. Further changes were suggested at the May working group and these will be incorporated in a rev 2 document for the July working group. One item has been posted on the SCSI BBS concerning over/under run counters that Greg would like comments on. 10.6 SCSI-2 Document Restructuring The May working group received a proposal from Ralph Schultz to break up the SCSI-2 document along the lines of the IPI document structure. Much discussion ensued at the May working group, but no resolution was reached. A motion to alphabetize commands within each device type passed unanimously. An action item was given to Larry Lamers to coordinate the update. The next revision is to merge group 0 and 1 commands within each device type. An experiment on removing change bars and using strike- outs and italics to indicate changes is being conducted. There was no opposition from the membership. 10.7 Microcode Download X3T9.2/87-7 rev 2. Bill Spence has revised his proposal from the comments received at the working group. A form of the WRITE BUFFER command is used to send the microcode to the target, with no requirements on the format of the data. A "save local copy" function has been added. A function was also added to load the code from removable media. An upload function was added to the READ BUFFER command to capture the microcode from the target. A lengthy discussion ensued with the following results: Delete items 5 & 6 on page 1. Pages 3-5 are of academic interest and are deleted. Delete the implementor's note. The remaining document was accepted for incorporation in SCSI-2. 11.1 Working Group Agenda The agenda includes all the new documents and the items identified on the SCSI BBS, as well as twenty items carried over from the prior working group. The agenda of the July general working group: Day one will review outstanding proposals minus the tape items. Day two will start with the review of section 8. If this task is completed, we will return to outstanding proposals. The priority of consideration is based on longevity. Tape items will start at noon of day three. See 13., Meeting Schedule, for the meeting location and dates. 11.2 Criteria For Forwarding SCSI-2 There was a variety of suggestions on what should be included in SCSI-2 prior to forwarding it to X3T9. Paraphrased somewhat they were, "We should forward it as soon as my proposals are included." Gene Milligan has accepted an action item to generate a Project Proposal (SD3) for SCSI-3. This would allow the Task Group to continue work on those items that are not completed in time for SCSI-2. Jeff Stai moved that X3T9.2 establish the following schedule for the SCSI-2 document: 1) All technical issues on SCSI-2 shall be completed by the October plenary meeting. 2) A vote to forward the document is scheduled for the February 1988 plenary meeting. The motion was seconded by Skip Jones. Jim McGrath moved that the motion be amended as follows: 1) All technical issues on SCSI-2 shall be completed by the December plenary meeting. 2) A vote to forward the document is scheduled for the April 1988 plenary meeting. The motion was seconded by Bob Snively. 11 YES - 21 NO. Amendment failed. 30 YES - 5 NO. Motion passed. All new proposals should be submitted by the August plenary meeting. 11.3 SCSI-2 Editors John Lohmeyer stated that he had received a letter from John Hoy saying that due to an employment change he could no longer act as the editor of section 15. The following tentative changes (pending management commitment) were made to the editor assignments: Paul Nitza will edit sections 7 and 8. Larry Lamers will edit section 15 (and continue as general editor). Editorial schedule - The editors plan to have an editing session on July 16 and 17 following the July working group. Another session is being considered following the Wichita working group. Any person interested in editing should contact John Lohmeyer. 11.4 IMMED Bit on WRITE FILEMARKS & VERIFY X3T9.2/87-88 There was no disagreement over the intended change in X3T9.2/87-88. It would allow the target to return status as soon as the CDB is received and parsed. The only real question was in how to word the description. Eventually the proposal was accepted with the word "received" changed to "validated". 11.5 Initiators Providing Terminator Power A proposal is expected from Steve Kappes of Interphase to allow external power (power other than from the initiator or target) for termination. Discussion is tabled pending the proposal. 11.6 SCSI Bulletin Board System (BBS) Attached to the agenda and the revised document register was a sample session on the SCSI Bulletin Board. This was included for tutorial reasons and because there were several messages on the SCSI BBS that the Chair felt were of general interest. John Lohmeyer briefly discussed how to use the BBS. Since many committee members do not have access to the BBS, proposals received on the BBS will be distributed in subsequent mailings. To have a document considered as a proposal it should be uploaded as a file with a message requesting John Lohmeyer to assign a document number. In addition, public messages which have significant content will be printed and distributed. Message #3 from Greg Floryance on what constitutes a READY condition -- The result of this discussion is that paragraph 6.1.3 has been changed to delete the paranthetical phrase "(after the logical unit becomes ready)" and a third condition is added to the list of thing that reset a target "or by a power-on reset". Message #4 from John Lohmeyer on whether a unit reservation followed by an extent reservation from the same initiator is permissible. Several people felt that this condition is covered by (or in any case, should be covered by) superseding reservations. John accepted an action item to review the wording of superseding reservations. 11.7 Review of New/Revised Documents X3T9.2/87-7 Rev 2 - Covered in item 10.7. X3T9.2/87-59 Rev 2 - Covered in item 9.3 X3T9.2/87-76 Rev 1 and X3T9.2/87-77 Rev 1 - Added to the Working Group agenda. X3T9.2/87-88 - Covered in 11.4. X3T9.2/87-89 - Richard Hodson of Micropolis presented a document describing a potential flaw management problem using REASSIGN BLOCKS, including one possible solution. Skip Jones offered a specific proposal for a 12-byte TRANSLATE command. A more refined proposal is to be developed for the working group. X3T9.2/87-91 - Added to the Working Group Agenda. X3T9.2/87-92,93,95,96 - Added to the Working Group Agenda. X3T9.2/87-94 - Added to the Working Group agenda. X3T9.2/87-97,98 - Added to the Working Group agenda. 11.8 X3T9.2 and X3T9.3 Merger John Lohmeyer spoke to the issues of joint meetings and the attendant problems with document distribution. He stated that the joint meeting approach is difficult and that he would like to proceed with the merger. A single plenary meeting with the various projects largely developed in working groups is the proposed structure. There ensued a lengthy discussion on this topic, including issues of voting, agendas, ability to focus on tasks, and efficacy of meetings. Gene Milligan moved that X3T9.2 and X3T9.3 request of X3T9 that they be merged into one task group to be known as X3T9.1 with the following general charter and general voting rules: 1) Development of peripheral subsystem interfaces including application as peer to peer interfaces including projects such as IPI, SCSI, and ESDI. 2) Votes to request project authorization and to take final action such as forwarding are to be by the full task group. 3) Votes to implement and/or change drafts are to be by attendees in split working sessions or the full committee in accordance with their previously designated area of interest allowing members, for example, to vote only in ESDI and no other interfaces if they so choose. This motion specifically requests that X3T9 attempt to implement the merger as of the August meeting and that they arrange with the X3 Secretariat to maintain John Lohmeyer as the Chair and Dal Allan as the Vice-Chair. Jeff Stai seconded the motion for both X3T9.2 and X3T9.3. Jeff moved that the motion be amended by deleting paragraphs 2) and 3). Bob Snively seconded the amendment for X3T9.2 and P. Nitza seconded the amendment for X3T9.3. The amendment passed in both Task Groups: 36 YES, 6 NO. Arnold Roccoti moved that the motion be ammended to strike the recommendation that the merged task group be called X3T9.1. Dave McIntyre seconded the motion. The motion carried: 30 YES, 3 NO. The amended motion is as follows: Gene Milligan moved that X3T9.2 and X3T9.3 request of X3T9 that they be merged into one task group with the general charter to be the same as the charters of X3T9.2 and X3T9.3. This will include the existing projects of both task groups. This motion specifically requests that X3T9 implement the merger as of the August meeting and that they arrange with the X3 Secretariat to maintain John Lohmeyer as the Chair and Dal Allan as the Vice-chair. X3T9.3 voted 10 in favor - 6 opposed. X3T9.2 voted 27 in favor - 3 opposed. (Chairman's note: This motion received considerable debate at X3T9, where the motion was amended to include voting rules, again. The motion was defeated 6-7-1. A motion to separate X3T9.2 and X3T9.3 again with SCSI, ESDI, and Flexible Disk assigned to X3T9.2 and IPI, SMD, RDI, and HSC (if it becomes a project) assigned to X3T9.3 passed unanimously. X3T9, as part of this motion, recommended that SMC solicit new officers for X3T9.3 as the Vice-Chair position is vacant and Gary Robinson has applied for the X3T9 International Representative position.) 12. Review of New Action Items 12.1 Ed Calkins will check on IBM position concerning availability of the IBM current-mode differential drivers and receivers. 12.2 The Queuing Ad Hoc will review the IPI model on queuing. 12.3 Bob Snively will revise X3T9.2/87-52 to include the comments from the June plenary meeting. 12.4 Bob Snively will prepare a proposal on SCSI version switching. 12.5 Larry Lamers and the section editors will revise the SCSI- 2 draft document to present the commands in alphabetical order. 12.6 Bill Spence will revise the EOT definition in the tape glossary with the assistance of Gary Stephens and Jim Semenak. 12.7 Gene Milligan will prepare a draft SD-3 for SCSI-3. 12.8 John Lohmeyer will review the unit vs extent reservation issue that he identified to determine whether superseding reservations adequately covers this situation. 13. Meeting Schedule The next meeting of X3T9.2 will be August 17-18, 1987 at the Clarion Hotel in Colorado Springs, Colorado [(303) 576-5900]. Please mention the "ANSI X3T9" meeting when making reservations to receive the special room rate of $75.00 for single occupancy and $85.00 for double occupancy (including tax). The plenary meeting schedule for 1987 and 1988 is: October 12-16, 1987 Saratoga Springs, New York December 7-8, 1987 San Diego, California February 22-23, 1988 Phoenix, AZ April 25-26, 1988 New Orleans, LA June 20-21, 1988 Vancouver, B.C. or Seattle, WA August 15-16, 1988 Denver, CO October 17-18, 1988 Boston, MA December 5-6, 1988 San Diego, CA (Chairman's note: The 1988 meeting locations were selected at the subsequent X3T9 meeting based on straw votes taken at the X3T9.2/3 and X3T9.5 meetings.)
