Check using Edit Settings on your backup solution's virtual machine to see if it has a hard disk attached that belongs to a different virtual machine. From here I deviated from the KB article. This reduces the amount of lock troubleshooting to just the VMkernel. You might find a few surprises from old data that has not been properly cleaned up on VMFS volumes. More about the author

Remove one of the disk from the VM and attempt to power on.Opening a Support RequestIf your problem still exists after attempting the steps in this article, contact VMware Technical Support The Hot-add feature of the backup software to the backup server VM meant that the backup server had a lock on on of the vmdks. If you do make changes directly to this file, make a backup copy first.
Looking at -delta.vmdk files The -rdm.vmdk file. In such cases, if the backup fails and/or the host shuts down, the backup virtual machine may still have another virtual machine's vmdk file(s) attached. First step is to find all snapshots and delta disks on the datastores: # find /vmfs/volumes/ -name *-delta*;find /vmfs/volumes/ -name *-0000* /vmfs/volumes/[id]/[VM]/VM-000002-delta.vmdk /vmfs/volumes/[id]/[VM]/VM-000002.vmdk /vmfs/volumes/[id]/[VM]/VM_1-000002-ctk.vmdk /vmfs/volumes/[id]/[VM]/VM_1-000002-delta.vmdk /vmfs/volumes/[id]/[VM]/VM_1-000002.vmdk As you can see above Vmware Snapshot File Extension You can add any text or html markup here.

As I knew the VM I moved straight to locating the lock and removing it. Virtual machines will lock the .vswp, -flat.vmdk and -delta.vmdk, .vmx and .log files during runtime. The locking mechanism for VMFS volumes is handled within VMFS metadata on the volume.Determining if the file is being used by a running virtual machineIf the file is being accessed by http://webjak.net/vmware-unable/vmware-unable-to-generate-initrd.html Assess the virtual machines current state on the host: For ESX, run this command: # vmware-cmd

The descriptor file also contains a pointer to the large data file as well as information on the virtual disks drive sectors, heads, cylinders and disk adapter type. Only one of these files exists regardless of the number of snapshots running, as they all update this single file. When the snapshot is deleted, these files are automatically deleted after they are merged back into the original flat.vmdk file. Vmware Delta Disk If this is the case, collect diagnostic information from the VMware ESX host and submit a support request.
