iSCSI: Plugging holes in CmdSN

["Lakshmi Ramasubramanian" <nramas@windows.microsoft.com>]

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!
