BTAVM2273W Unable to find file "File name" which is the backing device of the virtual disk "Disk name" of hypervisor Hypervisor name, virtual machine "VM name".
Explanation
The backing info of the virtual disk was not found by the ESX probe. This happens when either the virtual disk was created after the latest datastore scan or VM was probed while its snapshots were being deleted.
Because the virtual disk could not be correlated to its backing device, the capacity of the VM will be reported wrong in Spectrum Control.
Action
Rerun the hypervisor probe.
