There is one VM in our prod environment that I am unable to backup due to unable to quiesce the VM. I looked at the event log of the machine and found out Event ID 157 and Event ID 15 started occurring same time the backup started failing.

Looks like there are phantom disks seen by the OS. Device Manager shows 2 drives and this is correct. I have storage migrated the VM but the error keeps on occurring meaning it is with the VM itself. System scan (sfc) not showing any error.
What are your thoughts on this?
