Results of Meeting
1. Opening Remarks
George Penokie convened the meeting at 9:00 am, Tuesday, January 09, 1996.
He thanked Jim MaGrath of Quantum for hosting the meeting.
This is a joint meeting of the X3T10 SCSI Controller Commands working group
and the RAB Host Interface working group. The purpose of the group is to
deal with interface issues related to using RAIDs. The study group will
assess the issues and then formulate a strategy for dealing with them.
As is customary, the people attending introduced themselves. A copy of the
attendance list was circulated for attendance and corrections.
It was stated that the meeting had been authorized by X3T10 and would be
conducted under the X3 rules. Working group meetings take no final
actions, but prepare recommendations for approval by the X3T10 task group.
The voting rules for the meeting are those of the parent committee, X3T10.
These rules are: one vote per company; and any participating company
member may vote.
The minutes of this meeting will be posted to the SCSI BBS and the SCSI
Reflector and will be included in the next committee mailing.
2. Attendance and Membership
Attendance at working group meetings does not count toward minimum
attendance requirements for X3T10 membership. Working group meetings are
open to any person or company to attend and to express their opinion on the
subjects being discussed.

3. Approval of Agenda
The agenda developed at the meeting was approved.
4. Report on status of the SCC standard
The SCC standard rev 6 has exited it's second public review without
comment and will move to X3 for approval.
5. Discussion of SCSI-3 fault tolerant controller configurations
proposal
Steve Sicola presented his proposal for fault tolerant controller
configurations. After his presentation a long discussion ensued about the
best solution to his problem. The following solution was agreed to:
-Create a new SCC service action that would report the world wide
identifier assigned to all volume sets the addressed SCC device is aware
of.
Note: Not all the volume sets the addressed SCC device is aware of need to
be configured by the addressed SCC device or have LUN_V values assigned by
the addressed SCC device.
-Create a new SCC service action that would assign a LUN_V value to a
volume set identified by a world wide identifier. A SCC device should only
allow volume sets that do not already have a LUN_V assigned to be assigned
the LUN_V.
6. Action Items
a)Steve Sicola will prepare a revision of the SCSI-3 fault tolerant
controller configurations proposal.
7. Meeting Schedule
The next meeting will be hosted by QLogic in San Diego at the Hyatt
Islandia Hotel on March 12 from 9:00AM to Noon.
8. Adjournment
