i'm running into an issue with a VMware hotadd proxy, Windows 2012 R2 fully patched, backing up a vSphere 6.5 environment running latest patches. Case id is 02189771
i never seen this one before in previous installs.
the backup fails when more than one SCSI (LSI, SAS) controller is presented to the proxy VM. But only in that case. When the backup is started with only the first SCSI controller active, everything runs fine.
I can see a VM disk being mounted (in disk management) during the backup in the case of 2 SCSI controllers on the proxy, but no read activity is performed at all on the mounted disk. it gets dismounted eventually, and the job fails (or fails over to nbd). I run the exact same job again, only this time with one SCSI controller on the proxy, job runs ok.
Any ideas? anyone seen this before?
VM hardware version 13
no AV active in proxy
automount is disabled
