IHAC is using is running SAP/Windows on filer, the Windows is SAN booted and with SnapDrive installed. They are using Legato Networker to backup OS and Application files.
During the backup, we find that Networker will use VSS for the backup, but it is using ‘Data ONTAP VSS Hardware Provider’, but not use ‘Microsoft Software Shadow Copy provider 1.0’, which caused to create snapshots on filer, we have tried this solution https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb37896 but not work.
Does anyone know how to disable Networker to use ONTAP VSS Hardware Provider and to use Microsoft Software Shadow Copy Provider?
Can you stop the Data ONTAP VSS Hardware Providerservice from control panel? Then Networker will probably look for another provider. I think the Microsoft VSS specifies the order of providers is first harsware then software. -Wei
As long as the Data ONTAP VSS hardware provider is installed and registered (which is done as part of SnapDrive Windows installation), it will be used to create snapshot of NetApp LUNs - this is the default behavior. To avoid this, the VSS requester (Legato Networker in this case) needs to choose the software system provider explicitly while creating the snapshot set.
We had this problem as well and simplest way to avoid it is not to use VSS on this client. To do this, add "VSS:*=off" to the "Save operations:" field of the "Apps & Modules" tab on the clients properties page.
