Any ideas atleast ?

It seems to be working fine if the shares on the local storage. I dont see even a single illigitimae resource movement.

But when it was on SAN, the resource moves regularly because of one more error messages related to availability of Q and E drives to the active node . If it sence that the specific shared drive is not available the resource moves to another node and wise versa.

Any idea ?

But no!  the  cluster failed over to other host with out any reason, I dont see any error event inthe System logs expect the event whch says the resource has failed over...

Any idea again...???!!!
