Every once in a while you may reboot your NAS w/o rebooting the ESXi server.. From my experience, you are in for some pain. Previously I found that you would have to unmount the NFS share, remount, remove all VMs, and re-add all of them.
So how do you fix the (inactive) and inaccessible?
~ # esxcfg-nas -l <volumeName> is /volume1/ESX from <IP> unmounted unavailable ~ # esxcfg-nas -d <volumeName> NAS volume <volumeName> deleted. ~ # esxcfg-nas -a -o <IP> -s /volume1/ESX <volumeName> Connecting to NAS volume: <volumeName> <volumeName> created and connected.
After doing this, all of the (inaccessible) boxes should start popping back up as their real names. It *may* require a reboot. Older ESXi versions wouldn’t re-add, and doing it once at a time was quite a pain.
