when a logical unit is not accessible for security reasons (06-219r0). The
group agreed that the editor should assign the additional sense code value,
guided by the recommendations in the proposal. George Penokie requested that

Ready command be removed from the proposal and Avraham agreed to revise the

(06-248r1) [McFerrin]
Bill McFerrin presented a proposal to address several MMC-5 Letter Ballot
comments by removing the PREVENT ALLOW MEDIUM REMOVAL command from SPC-4 and
placing it in other command set standards (06-248r0). The group insisted the
proposal explicitly list SBC-3, SSC-3, SMC-3, and OSD-2 as standards into
which the removed SPC-4 text will be placed.

command, and related aspects of SBC-3 (06-034r3). The group requested several
changes and Rob agreed to prepare a new revision for consideration at the next
meeting.

5.3.1 SES-2 Display element enhancements (05-011r2) [Elliott]
Rob Elliott presented a proposal to add displaying characters on 7-segment
LEDs to SES-2 (05-011r1). He noted that the previous discussion of this
proposal produced requests that it be made more general and support larger
numbers of characters. The intervening months have demonstrated no need for
larger numbers of characters, whereas supporting small numbers of characters
has become more important. Therefore, addressing large numbers of characters
has been dropped as a goal for the proposal.
The group requested that the ordering of character delivery be rigorously
related to the ordering of the displayed characters and Rob agreed to revise
the proposal. Other changes were agreed to for the revised proposal.
Rob Elliott moved that 05-011r2 (r1 as modified) be recommended for inclusion
in SES-2. Mark Overby seconded the motion. In the absence of any objections,
the motion passed unanimously.
5.3.2 SES-2 Internal/External Vendor Specific connectors (06-200r1) [Penokie]
George Penokie presented a proposal to allow differentiation of internal and
external vendor specific SAS connectors (06-200r0). The group requested
modifications in the code values assigned and their meanings. George agreed to
modify the proposal.
George Penokie moved 06-200r1 (r0 as modified) be recommended for inclusion in
SES-2. Rob Elliott seconded the motion. The motion passed 12:2:7.
5.4 Other Proposals
5.4.1 ADC-2, SPC-4, and SSC-3 Vendor-specific service actions for MAINTENANCE
IN/OUT (06-223r1) [Banther]
Michael Banter presented a proposal to define eight vendor specific service
actions in the MAINTENANCE IN and OUT commands (06-223r0). Several people
complained about assigning vendor specific uses where standardized uses might
be more appropriate.
Michael Banther moved that 06-223r0 be recommended for inclusion in SPC-4,
SSC-3, and ADC-2. Paul Suhler seconded the motion. The motion failed 2:2:13.
