Brian,
In SPC-2 look in section "7.3.5 Command support data". It is part of the
Inquiry command and does not work very well, if you can even find anyone
that has implemented it.
Bye for now,

Reporting supported opcodes for an SPC-2 compliant scsi device

I was hoping I could leverage the knowledge of this board to help me
|from going cross-eyed.
Is there an SPC-2 command that will tell me what opcodes a given scsi
disk device supports? For SPC-3, I'm aware of the 'REPORT SUPPORTED
OPERATION CODES' command, but I don't see that command in the SPC-2
spec? Is there some other way to determine this information?
Working on a linux platform, I'm using the sg driver to send passthrough
commands to my target devices. When I try to issue a persistent
reservation out command, I seem to get into a hung state with a final
return value indicating that a reset occurred. My persistent reservation
in command do seem to work, however.
Thanks,
Brian
