Ah. Far better.
What about delegating FORMAT UNIT to the control LUN, and not
implementing it for the individual disk LUNs?
That would make an even stronger case for having a control LUN;
with that there wouldn't be any problem with having to synchronize
across LUNs etc.
It sounds to me like NVMe might be a much better model for this drive
than SCSI, btw :)
So you found a document that outlines NVMe's architecture! Could you
share the url (no marketing BS, please)?
And a serious question ... How would you map NVMe's (in Linux)
subsystem number, controller device minor number, CNTLID field
(Identify ctl response) and namespace id onto the SCSI subsystem's
h:c:t:l ?
