I get the following error when trying to access a one of my VM's console in VI Inventory - "Virtual machine config file does not exist".
In vmkernel I find many errors messages like:
vmkernel: 15:13:16:42.169 cpu3:1091)<6>Debug scsi underrun
vmkernel: 15:13:16:10.703 cpu3:1041)WARNING: FS3: 5507: FS 479885c6-516e1dc6-4c5b-00145ec2c8ec may be damaged. Corrupt lock detected: [type c2c2c3c2 offset 14033993530586874562 v 14033993530586874562, hb offset 14033993530586874562
vmkernel: gen 14033993530586874562
Is the VM on the same storage as the Vms you can access or different storage - I've seen a similar error when we lost connection to the SAN - we had problems accessing one VM that we were restarting after patching and then we eventually lost communications to all the VMs. Had to represent the servers to the SAN and that fixed the problem.
You can also check in the datastore to verify that the config file still exists.
I have find one more error message in vmkwarning:

I would backup the VM data using traditional backup means.
THe main issue is that the mount point looks to have gone away on your ESX server, this is never a good thing. Which means the files that the VM is using have also gone away.
I would check presentation, zoning, and possibly reboot the ESX host. The LUN itself may also be corrupt.
