failed to open (The specified virtual disk needs repair)
An unexpected failure of the ESXi host could cause the virtual disk to get into repair mode.
To resolve the issue, identify the vmdk file and repair it.
vmkfstools -x check /<path to VM folder>/VM.vmdk
If the following output is seen, run the following command in step 3
root@esx:/vmfs/volumes/datastore/VMfolder] vmkfstools -x check VM.vmdk
Disk needs repair.
Caution: Ensure a backup copy of the vmdk descriptor and flat (if snapshots are involved, delta files and its descriptor files) is made before proceeding.
vmkfstools -x repair /<path to VM folder>/VM.vmdk
root@esx:/vmfs/volumes/datastore/VMfolder] vmkfstools -x repair VM.vmdk
Disk was successfully repaired.
Power on the virtual machine.
