Hi,
First of all, have you tried logging into the ESXi directly, not through vCenter Server? This might give you a better idea.
Anyways, the following esxcli command will show you the list of virtual machines running within the ESXi server:
esxcli vm process list
Sample Output:
test
World ID: 13572
Process ID: 0
VMX Cartel ID: 13566
UUID: 11 22 33 44 55 66 77 88-99 11 22 33 44 55 66 77
Display Name: test
Config File: /vmfs/volumes/"VMFS Volume"/test/test.vmx
test1
World ID: 13573
Process ID: 0
VMX Cartel ID: 13567
UUID: 11 22 33 44 55 66 77 88-99 11 22 33 44 55 66 78
Display Name: test1
Config File: /vmfs/volumes/"VMFS Volume"/test1/test1.vmx
Then, copy the Config File bit, e.g. /vmfs/volumes/"VMFS Volume"/test1/test1.vmx and navigate to the path if the files are still there.
If not, try restarting the management services.
Please keep me updated on how it goes.
Regards,
Steven.
