Backup fails with "Virtual Machine is configured to use a device that prevents the snapshot operation." (4045416)

When attempting a backup of a VMware virtual machine, it fails with the following error message:

• API Call failed with message: Virtual Machine is configured to use a device that prevents the snapshot operation. Device is a SCSI controller engaged in bus-sharing.

Microsoft Clustering requires bus-sharing. If you have a virtual machine that has a device engaged in bus-sharing, you cannot create snapshots for the virtual machine. This is a limitation in the VMware infrastructure.

Since vRanger B&R requires snapshots for agentless operations, this error is received from the VMware API.  

If bus-sharing is not required, please reconfigure the virtual machine. However, if bus-sharing is required, you can use the vRanger Physical Client in order to backup the virtual machine.

Please refer to the VMware KB 1006392
