Re: iSCSI: Plugging holes in CmdSN

["Julian Satran" <Julian_Satran@il.ibm.com>]

Yes an initiator can send a reset and
have the target completely clear. However bear in mind the recent changes
in SPC3 and SAM with regard to support for  reset 
Reset will also clear commands already
in execution and (depending on the type of queuing supported) commands
from other initiators.

Subject	iSCSI: Plugging holes in CmdSN

If the target detects data
digest error in a PDU,
and sends Reject the initiator

 
 * MAY retry the command
with the same CmdSN, TaskTag, etc. 
 
 * Or, Send a Task
Mgmt command to ABORT TASK that task.
 
Target will not advance
ExpCmdSN until initiator does something
to clear the rejected command.
 
But, can the initiator send
a Task Mgmt command with function
LU Reset (instead of ABORT
TASK) as IMMEDIATE command? Should 
the target then clear the
rejected command and any command that 
was received after that?
And, advance the ExpCmdSN so that initiator
can proceed with that session?
 
thanks!
