Discussion of 12-104 rev. 3 (Add progress indication to SYNCHRONIZE CACHE
commands) at the July CAP meeting suggested adding a two bit mode page
field to control which response should be provided. The three choices are
unsupported, supported with queuing commands, and supported with aborting
commands. That discussion didn't recommend which mode page to use, however.
I think the Control Extension mode page is the most obvious choice (there
aren't any two bit fields available in the Control mode page unless we
either make the page larger or break into an obsolete field). Does everyone
agree with this choice? If you think a different mode page is more
appropriate, please reply to this email.
