Did you tried opening it from the vcenter Client UI. It may be happend due to the issue in network .
you can follow this to troubleshoot this situation.
Try these steps :
A. Connect directly to host and see if you are still face the same issues
B. Browse to the datastore and see if the VM's are located.
C. Try restarting the management agents
D. Try to unregister and register the VM again to inventory .
Assuming that the VM's are up and running. Just that the VM's are in invalid state.http://www.myitblog.in/
It seems this would be an issue with your SAN, or the network that connects you to it.
you need to check this with your network team..
Rebooting SAN also didn't help, Network connections were perfect. I was unable to trace the .vmx files of the VMs when i browsed the shared datastore. I wasn't able to unregister VM as the option was greyed out.
Hi Sunny, This could not always be issue from host or N/W, check with storage team metadata on the storage LUN might have corrupted.
