Sorry for late reply. Configuring email client took a while.

Trigger failover from controller reset path can be removed, as
keep_alive timer failure would trigger failover.

What if target controller resets and comes back up within timeframe
that keep-alive timer gets serviced. This will lead to aborting of 
all IO request after multiple retries and retries completed within
same time frame before another keep_alive would get serviced. 
This will not trigger fail over.
