Re: error in data cmd

Prasenjit,

I assume that you are talking about a format error, an inconsistency, a
data-integrity error etc.
For all those - since there is no recovery involved - the target should
drop the packet and possibly all
subsequent packets and terminate the command after a long delay with an
error condition.

After several such errors the session should be closed.

Regards,
Julo

Assuming there is an error in the iSCSI DATA command, the target can

(i) drop the ball
(ii0 abort the transaction (Fibre Channel)
(iii) send back a repeat  RTT (sometimes counter-productive)
(iv) send back an iSCSI_CHECK response

What does iSCSI intend to do?
