Symptoms

  • VM Instant Access restore is performed using the NetWorker VMware Protection (NVP) vProxy appliance.
  • The recovery completes successfully but there is an error when using VMware storage vMotion to migrate the VM from the temporary NFS datastore on the Data Domain to a permanent datastore.
  • The error shown in VMware reports:
Invalid Configuration for device '##'

Cause

This is not a NetWorker issue. The Instant Access Recovery image is an exact copy of the original VM and its configuration.  The source VM was connected to a virtual Distributed Switch which was not present in VMware on the target host. The missing virtual Distributed Switch on the target host caused the vMotion to fail.

Resolution

VMware KB: 2102192 This hyperlink is taking you to a website outside of Dell Technologies. details the following workaround: 

To avoid this issue, before performing Storage vMotion, detach the virtual NIC from the distributed virtual switch by editing the settings of the virtual machine:

1. To access the virtual machine settings, select the virtual machine in the left pane in the vSphere Web Client.
2. Click the Manage tab, then click Settings and then click VM Hardware. If a virtual NIC is attached to a distributed virtual switch that does not exist on the host, the Attachment window displays no information.
3. To detach the virtual NIC from the non-existing distributed virtual switch, click the Network adapter to select an alternative option from the menu cascade (for example VM Network).
4. Click OK to save the changes.

If you get the "Invalid configuration for device 13" error while performing Storage vMotion, disconnect the NIC before initiating the migration.
