Regarding the following ZBC r04a text ...
220.127.116.11.1 Writing in sequential write required zones
If the value in the MAXIMUM NUMBER OF OPEN SEQUENTIAL WRITE REQUIRED
ZONES field is non-zero (see 6.4.2) and the actual number of zones with
a Zone Condition of EXPLICITLY OPENED is equal to the value in the
MAXIMUM NUMBER OF OPEN SEQUENTIAL WRITE REQUIRED ZONES field, then a
command that writes to or attempts to open a zone with a zone condition
of EMPTY or CLOSED is terminated with CHECK CONDITION status with sense
key set to ABORTED COMMAND and the additional sense code set to
INSUFFICIENT ZONE RESOURCES as described in 18.104.22.168.6.
The ZAC letter ballot reviewers are unwilling to move the ZAC equivalent
text out of the subclause titled "Opening Sequential Write Required
zones" which was created especially for this purpose and which appears
after the equivalent of 22.214.171.124.1 in the working draft. The appearance
of "or attempts to open a zone" in the text (which has nothing to do
with write commands) has been cited as the justification for a separate
This author rather prefers the separate subclause, but also wonders if
the complaints are not another manifestation of inappropriately
obsessive calls for word-for-word matches between ZBC and ZAC. Since
such an absolute goal is impossible starting with "application client"
vs "host", blind copying must be questioned when it becomes too much of
a good thing.
All the best,
