We have an MSA 1500 with dual controllers. Each had a single HBA, and each\nHBA attached to a seperate switch. When one of the HBA's in a server failed,\nwe discovered that the path to the standby controller did not function,\nobviously. So we were told my HP to buy a switch or a hub to rpovide access\nfrom each controller to each switch- the hub was signicantly cheaper.\n\nSo now we have 2 - 2 port hubs rather than a single HBA. And when I enable\nthe port where the second port in the hub is attached to (on the opposite\nswitch of the working one) we get 2 failed ports. I've contacted HP, and\nthey're lookign into it... any ideas? Is there some kind of conflicting\npath?
