Re: iSCSI : Abort Task Response violates SAM-2.

["Prasenjit Sarkar" <psarkar@almaden.ibm.com>]

The only constraint imposed is to ensure that a status for an aborted task
should not follow a task management response for that task, so a response
of
FUNCTION COMPLETE for a task that is not found is perfectly valid.

Julian,

SAM-2 Rev 15 Section 6.1 states that  :

"a response of FUNCTION COMPLETE shall indicate task was aborted or task
was
not in task set".

The iSCSI draft is violating SAM-2 by returning "task not found" when the
task
was not in task set.

Thanks,
Santosh
