Re: Avoiding deadlock in iSCSI

That is the way ACA works - and that is what I understood from Ralph's
messages on the CA/autosense track (I was unwilling to give up on CA
exactly for this type of action - until I understood that ACA is replacing
my
old fashioned CA).

Part 1) Add a new task management command: CLEAR TASK SET FULL

Part 2) Once a target returns TASK SET FULL, it must return TASK SET
FULL for all non-ACA attribute commands until it receives a target
reset, LUN reset, ABORT TASK SET, or CLEAR TASK SET FULL.

ACA attribute commands may proceed against a target, even when the
TASK SET FULL error condition is present.


I'm not sure about backward compatibility. I'd appreciate feedback on that.
