Hey guys,

I've been looking through our SAN traffic, which contains two separate Fabrics, each with core Cisco MDS9513 (with the DMXs are attached to) and edge MDS9509 switches (with hosts attached to). I've noticed that some windows hosts with PP installed do not split the traffic between the two Fabrics...

I've checked PP, license, policy (SymmOpt), ISLs, HEAT report was ok too. One of the hosts is even a part of a cluster which is connected the same as the other host, but only one of them do not split traffic. Traffic on those "problematic" hosts ranges betweem 5% on 1 fabric and 95% on the other and sometimes 20%-80%... All other 300+ hosts usually split it even at 50%-50%.

Any ideas?

Thanks,
Maxim
