Hi I am still struggling to resolve this issue, I only get the problem when I am moving/migrating virtual computers to the open-e FC volumes, doing the same to Sanmelody Datacore FC volumes on the same esx server works fine. Tired different server hardware/fibre cards and 2 x brocade sikworm switches. I have raised with support and so far nothing possitive.

I have tried ESX 3.5 and 4, vm powered on or off still the same. Any one else experianced this let me know
