sequences to zoning (06-181r1). The proposal contained two options for stating
the same requirements and the group expressed a preference for the second.
Concerns were discussed and resolved related to not changing to the default
zone group in some scenarios where the attached device really did not change.

5.4    SAS-2 Add expander change count to all SMP functions (06-197r1) [Elliott]

Discussion of this topic was deferred due to a lack of time.


6.     Self-configuration clarifications

6.1    Discovery - Configuring bit (06-097r2) [Symons]

Tim Symons presented a proposal to clarify/define/redefine the Configuring bit
(06-097r2). The group discussed making the Configuring bit Obsolete and
determined that the bit could be useful as a way to indicate the I_T Nexus
Loss Timeouts should not be applied.

Tim agreed to work with Rob Elliott to revise the proposal for consideration
at the next meeting.

6.2    Self configuring devices (06-098r3) [Symons]

The group discussed the general concept of route table configuration. It was
agreed that the Discover Process included sending Discover and Report General
SMP functions to develop an image of the topology. The Configuration Process,
wherein Configure SMP functions are sent to table-routed expanders, can be
viewed as a subroutine within the Discover Process.

The group requested corrections to several of the example configurations in
the proposal and then requested two additional examples. Tim agreed to revise
the proposal for consideration at the next meeting.

6.3    SAS-2 Self-configuring expander status (06-187r0) [Elliott]

Discussion of this topic was deferred due to a lack of time.


7.     Major new features

7.1    SAS-2 Allow table-to-table expander attachment (06-189r0) [Elliott]

Rob Elliott presented a proposal to allow table-routed phys to be connected to
table-routed phys (06-189r0). The group discussed the merits of the proposal,
how it would simplify SAS configuration rules going forward in time, and
possible removal of the term 'fanout expander'.

The group recommended several changes, including trying to more clearly
differentiate between self-configuring expanders and configurable expanders.
Rob agreed to prepare a new revision of the proposal for consideration at the
next meeting.


8.     New SMP functions

8.1    SAS-2 SMP Lists (DISCOVER LIST) (06-037r3) [Johnson]

Steve Johnson presented a proposal to define a new SMP function that returns
information about multiple phys (06-037r3). The group requested several
changes and Steve agreed to prepare a new revision for consideration at the
next meeting.

8.2    SAS-2 Expander Routing Table (REPORT ROUTE TABLE) (06-078r0) [Johnson]

Discussion of this topic was deferred due to a lack of time.

8.3    SAS-2 SMP CONFIGURE PHY ZONE function (06-201r0) [Symons]

Discussion of this topic was deferred due to a lack of time.

8.4    SAS-2 SMP CONFIGURE ZONE PERMISSION function (06-202r0) [Symons]

Discussion of this topic was deferred due to a lack of time.

8.5    SAS-2 SMP REPORT ZONE PERMISSION function (06-203r0) [Symons]
