Re: [EXTERNAL] SV: Ndmpcopy times out...

So based on your testing,  the timeout does only affect the actual cluster
login. It does not propagate to the SP.

Autologout: System Console being disconnected due to inactivity


This is the interaction of the SP and ONTAP. Remember, you do the "system
console" to get to the "serial" access of the node.
That is what is timing out. If a command is running via system console it
should continue to run.
If you are getting that message (above), sounds like a bug to me.
You could try to modify the SSH setting to enable the "keepalive" bit that
is supposed to send something benign every minute??
