I have blade servers with esx4.1i and shared SAS storage with 2 controllers.
Blade servers are connected with SAS storage over 2 SAS switch, eveyone with 8 SAS ports, with every SAS switch is connected to storage with 2 SAS cable.
So, I have 4 (four) cable between every host and storage. At host storage configuration options I see 4 active paths.
But at Storage Views, for every datastore, multipathing status is Partial/No Redundancy. Why?
I didn't try to physically pull out the cables, but I will do it as soon as possible to be sure.
Thanks on your opinion.
