Hyper-V Storage Live Migration Error: …not allowed because replication state is not initialized.

We had a Hyper-V server choke on some attached USB storage that was being used as a backup destination.

After getting things up and running we went to move one of the VM's VHDX file set and hit this:


Move Wizard

Storage migration for virtual machine 'VMName' failed.

Operation not allowed because the replication state is not initialized.

Storage Migration for virtual machine 'VMName' (GUID) failed with error 'The device is not ready.' (0x80070015).

Operation not allowed for virtual machine 'VMName' because Hyper-V state is yet to be initialized from the virtual machine configuration. Try again in a few minutes. (Virtual machine ID GUID)

The "fix" is to restart the VMM Service in an elevated PowerShell:

Restart-Service -Name VMMS

Once the service was restarted:


The move started without issue.
