5. virtual machine disk descriptor file shows normal and CID chain is not broken.
Reason:
The VMDK or Delta VMDK is locked by one of the esxi in the cluster. Even if we move the VM in the particular Host, VM will fail to power on or consolidate disk.
To identify which disk is locked, refer the /var/log/vmkernal.log
Solution:
Identify the ESXI host which is currently have lock on the Delta vmdk or VMDK with below command.
