VSS Snapshots Fail with the Message: "No Volume Connected to the Host”

Snapshots taken of a VMware Virtual Volume (VVol) using Volume Shadow Copy Service (VSS) fail if the VVol does not have its array serial number registered on the workstation. The error message "No volume connected to the host” is displayed.

This error occurs when you import a virtual machine (VM) containing the VVols to a new vCenter workstation. The registration information does not get added to the new workstation. You must manually add it.

  1. Power off the VM.
  2. Open the VMX file and add the following line for the VVol:
    disk.EnableUUID="true"
    NOTE: For information about locating the VMX file, see the VMware KB article Locating a hosted virtual machine's files (1003880)
  3. Power the VM back on.
