4. Old Business
4.1 SAS-1.1, protocol for changing driver amplitude (03-285r2) [Evans]
Mark Evans requested that discussion of this topic be deferred to the next
meeting, and that the content be deferred to SAS-2.
4.2 SAS-2 More counters (04-172r0) [Elliott]
Rob Elliott requested that discussion of this topic be deferred to the next
meeting.
5. New Business
5.1 SAS-1.1 revision 9 letter ballot comment resolution as of SAS1R09b
(05-169r1) [Elliott]
Rob Elliott led the group in a review of numerous SAS-1.1 Letter Ballot
comments (05-169r1). Rob recorded the resolutions agreed by the group for
inclusion in 05-169r2.
Ralph Weber moved that the two comments defining application client specific
coded values in the SMP Discover response be rejected. Bill Martin seconded
the motion. The motion passed 8:1:9.
5.2 SAS-2 Zoning (05-144r0) [Liao, Gorshe and Grieff]
Heng Liao presented an overview of a proposed SAS-2 Zoning feature (detailed
proposal 05-144r0). The group discussed the model and raised several issues.
Heng agreed to prepare a new revision of the proposal for consideration at the
next meeting and he agreed to post the overview that he presented.
5.3 SAS-1.1: BreakWait issue resolution (05-145r0) [Hoglund]
Tim Hoglund reviewed newly surfaced problems in the 05-093r1 changes approved
in March (minutes in 05-094r0) that are worse than the problems the proposal was
trying to fix (05-145r0). Concerns were raised that some devices already
shipping implement 05-093r1.
Tim's presentation also proposed fixing the problem by adding a Break Wait
Response to close a formal frame handshake as an airtight solution. The group
agreed to defer the handshake solution to SAS-2, and Tim agreed to prepare a
new revision of 05-145r0 containing the SAS-2 changes.
The group agreed to address problems caused by incorporating 05-093r1 as
responses to LSI SAS-1.1 Letter Ballot comments.
5.4 SAS 1.1 - Transport layer retry and argument passing fixes (05-143r2)
[Penokie]
George Penokie presented a proposal to correct numerous argument passing
details in the SAS-1.1 state machines (05-143r2). The group reviewed the
proposed changes page-by-page. The group requested changes and George agreed
to prepare a new revision.
5.5 SAS-2: New NOTIFY to indicate imminent power failure (05-167r0)
[Penokie]
George Penokie presented a proposal to add a NOTIFY primitive to indicate
imminent power failure (05-167r0). George noted that none of the NOTIFY
primitives are considered in the SAS state machines. Concerns were raised
about sending the proposed NOTIFY primitive just once.
George agreed to revise the proposal for consideration at the next meeting.
6. Review of Recommendations
No documents were recommended for inclusion in SAS-1.1 or SAS-2 during this
meeting.
