Powering on a virtual machine fails after a storage outage with the error: could not open/create change tracking file (2009244)

Virtual machine does not power on after a storage outage
You see the error:

could not open/create change tracking file vmdk_file_name
There are no CTK variables on the virtual machine configuration (.vmx) as described in vMotion fails at 78% with the error: Could not open change tracking file (2001004)
When virtual machine is powered on, you may see the error:

invalid signature change in tracking file

This issue may occur if filename-ctk.vmdk file has been created at some point in the past and has not been cleared since then.

To resolve this issue, remove or rename the filename-ctk.vmdk file:

Remove the hard disk specified in the error message from the virtual machine.
Open an SSH session to the host. For more information, see Using Tech Support Mode in ESXi 4.1 and ESXi 5.0 (1017910).
Navigate to the virtual machine's folder (/vmfs/volumes/GUID/vm_name).
Remove or rename the filename-ctk.vmdk file.
Re-add the hard disk back to virtual machine
Edit the descriptor file (.vmdk) and remove or comment out any references that specify use of a ctk file.
Power on the virtual machine.

04/04/2012 - Added suggestion to remove any ctk references in the .vmdk files.
