VMWare Virtual Machine wont power on from SAN

Hi,

Have been having issues with our cluster of VMWare VIrtual machines going down 1 by one of the last few days and losing there VMDK files to know where to locate and boot the machines virtual hard disk. These are running off 3 seperate ESX servers.

Have managed to restore a few virtual machines by recreating but the virtual machines that have multiple disk are causing issues.

When we try and boot one of these Multiple Virtual Machine Disk Virutal Machines after recreating all the relevent vmdk files for each disk we are getting the following error :

"Unable to access file [DE-SANVM1] DE-Exch02/DE-VMECH02-000002.vmdk since it is locked " 

and then it says Reason failed to lock the file.

We have this for the 3 multiple disk Virtual Machines.

check out this VMware Article, and use the lsof command to try and isolate the process which has locked the file.

Sounds like this could be a space issue.  When were the last good snapshots taken?  How much overhead storage do you have remaining?

After recent events, with issues and locking.

Restart your Host.

Also check my EE Article to see if you are running on snapshots.
