I am using 2 X HP DL360 G6 in cluster mode (vSphere 4 advance).
Recently I upgrade both ESX servers from version 4.1 (4.1.0, 320092) to 4.1 Update 1 (4.1.0, 348481).
After the successful process I wasn't able to start one of the VM's that uses pass-through nic card.
I reconfigure the pass-through nic card, restarted the host but when I'm trying to add pci device, it shows that the device is unavailable.
I even try to vmotion the machine to the other host and configure it from the beginning but the same results.
I guess that it something to do with the Update 1 because everything works fine before the upgrade
