We are putting our first physical Redhat (rhel 6.8) on a compellent. sc8000/scos 6.7.5.
I am using the multipath parameters that is advised in a Dell TID which is pretty much the defaults it says after rhel 5.4.
However when testing doing some SCP copies and pulling a fiber, my scp will stall for about a minute. During that time a multipath -l still shows 4 active paths. After a minute it will show 2 and my scp will resume. I have to believe I need another option to in order to getting data traffic from stalling out like that. It seems odd because the defailt is round-robin so not sure why it times out for a minute.
And to be clear this is pulling a 1 of 2 fibers from the phsyical redhat host to test a failure. Everything is zoned correctly too, ie my physical HBA zone to the virtual ports on the Compellent.
