I have placed SPC-2 revision 6 on the FTP site in

   <ftp://ftp.symbios.com/pub/standards/io/t10/drafts/spc2/spc2r06.pdf>

SPC-2 revision 6 includes all changes approved by T10, including
those changes approved by the November Plenary meeting.

For quick reference, here are the revision history notes that concern
revision 6, mostly incorporation of 98-203r9 (Persistent Reservations).

To maintain consistency in the additional sense code database,
additional sense code qualifier values other than those recommended
in 98-203r9 have been assigned to INSUFFICIENT REGISTRATION RESOURCES
and REGISTRATIONS PREEMPTED.  In 98-203r9, the cut and paste from the
model clause to the various annex clauses was a little too inclusive,
and editorial cleanup was applied during incorporation.  In the SMC
commands annex of 98-203r9, the reserve and release six and ten byte
commands were grouped as per the SBC tables and READ RELEASE
ELEMENT(10) was corrected to RELEASE ELEMENT(10).  The flowchart
figure was restructured slightly to reduce the amount of white space.

In addition to the changes described in 98-203r9, all text in the
various command descriptions that specifies the behavior of commands
relative to reservations has been marked for deletion.  The technical
editor believes that the text marked for deletion is superseded by
the new model information provided by 98-203r9.  During this process,
it was discovered that the REPORT DEVICE IDENTIFIER and SET DEVICE
IDENTIFIER commands were not represented in the conflicting
reservations tables in 98-203r9 and suitable entries were added to
the tables.

As per a fall working group discussion, usage of "SCSI-3" has been
changed to "SCSI" wherever possible.

Thanks.

Ralph...
