In my experience with ib-srp, I am not sure if there is such a thing as
link going down for a short time. When the link goes down, no matter how
short the duration (< 1s), IO fails over, this failover takes very long
time currently. Or, I would like to know if you can get a ib-srp
failover time

Hi Dave,
As long as we get faster failover I am happy with Bart's patch.
Currently when I run IO to several luns over multipath and the preferred
path goes down, the system hangs until the IO fails over. Even ssh'ing
into the systems take 20-30 seconds. I *suspect* that is because IO is

This conflicts with Bart's patches to improve failover; it will be much
better to use his approach to block the target rather than remove it
wholesale -- we could have lost connectivit
Thank you for clarifying!
