I was working on a case where live migration was failing for a cluster due to  unwanted disk was attached on the virtual machine VM1.

Here is the troubleshooting which I did to fix the issue.

 

Issue

=======================================================

Live migration is failing for the cluster ABC from host host1

Troubleshooting

=======================================================

– Found that all the VMs are synced with VMM and Hyper-V for the host host1

– Now refresh the Host and virtual machines and it come back but could see the below errors.

 

Error (23243)

A Virtual Hard Disk attached to VM1 does not have a VHD file path specified.

Recommended Action

Specify a path to a virtual hard drive file or remove this virtual hard disk.

 

Error (23234)

VM Refresher encountered an error while creating or updating VM VM1 with ID: 9725FC69-5FE3-4A72-9A7D-BFA516C42F7E. A Virtual Hard Disk attached to VM1 does not have a VHD file path specified.

Specify a path to a virtual hard drive file or remove this virtual hard disk.

Recommended Action

Validate the VM's configuration in Hyper-V, repair the VM in VMM, and retry the operation.

 

Error (23243)

A Virtual Hard Disk attached to VM1 does not have a VHD file path specified.

Recommended Action

Specify a path to a virtual hard drive file or remove this virtual hard disk.

 

C:\ClusterStorage\volume2\VM1\VM1 .vhdx

 

– Now checked the VM properties from hyper host and found that it is having 3 vhdx but actually it has 2 hard drive.

– Now we removed the unwanted disk from VM and refresh the Host, Cluster and issue got resolved.
