T10 proposals
Kevin,
I reviewed the following T10 proposals
and added some comments.
T10/06-272r3 Report
Element Info command
Background - does not mention if this
command is meant to be an eventual replacement for Read Element Status,
but the implication is that it is intended for this. This should
be mentioned. And along these lines, section 6.x.6 comments that
some RES characteristics are not represented by this command. These
characteristics should be addressed or mentioned for inclusion in another
new command.
section 6.x.4 - comment mentions possible
common element locations - add "tier" as a location if they want
to standardize.
section 6.x.6 - seems to be some overlap
and confusion with Static Information page ECBD bit and State descriptor
ED bit.
section 6.x.6 - what's the difference
between State Descriptor FULL and RMVD? Need both?
T10/07-199r0 SMC-3 POSITION TO ELEMENT
command clarification
section 6.8 says The element specified
by the DESTINATION ADDRESS field
may represent a storage element, an import/export element, a data transfer
element, or a medium transport element. Doesn't make sense for
medium transport element to be a destiniation since the MTE is what is
being positioned.
T10/06-442r3 SMC-3 Add PREVEN ALLOW
MEDIUM REMOVAL command
looks good
