Re: iSCSI - Question about StatSN and NOP-In PDU

Mark,

I am not sure that I understand what
is exceptional in this situation.
I assume that your Nop-In has TTT (it
is ping) and requests a Nop-Out.

Subject	iSCSI - Question about StatSN and NOP-In PDU

Our iSCSI target implementation generates an unsolicited
NOP-In PDU as a
"ping" mechanism after 5 minutes of inactivity within an established
connection.  We also increment the StatSN that is carried within that
PDU.
If the initiator happens to send a PDU at the exact same time as our NOP-In
PDU, the initiator and target StatSN values will get out-of-sync.

Is there anything in the Draft 19-90 specification that describes how to
handle this unique condition?
