RE: iSCSI Check Condition

[Black_David@emc.com]

The short answer is "Autosense is REQUIRED", see
section 2.4.5 of -06.  If CHECK CONDITION comes
back, the Initiator MUST look for the sense data
even if the Initiator doesn't expect any response
data from a successful command execution, and hence
the Target sends the sense data back with the
response.
