Snapdrive VSS hardware provider not working

[ Edited ]

I am trying to backup virtual machines using Veeam and the SnapDrive VSS hardware provider. I am unable to get it to perform the backups.

I am using Snapdrive 7.1 on Windows 2012 R2 hosts. The virtual machines reside on fibre attached LUN's presented from a NetApp FAS3240 running in 8.1.2 7-mode. Snapdrive is configured to run under a domain account which is a member of the Administrators group on the SAN, and is communicating via RPC.

 

When a backup job is started the following event logs are written:

 

CreateTargetLun failed.
Storage System Name = SAN02
lunPath = /vol/SNAPSHOTS/2_1_Snapshots
Snapshot copy Name = {e7a2fd17-3f7e-44df-a6d1-647fc0a3b02f}

Does anyone know why this keep failing?

Re: Snapdrive VSS hardware provider not working

Hi,

We support our Data Ontap VSS Hardware provider when the VSS requestor is our SnapManager.

you can use another requestor to call our provider at your own risk though.

with that said, the key error message you need to focus on is:

"The volume name 'sdw_cl_SNAPSHOTS_0' exists already."

I would ensure that the application is not creating more than one clones of the same volume at once, perhaps by putting database and logs in separate volumes....etc.

hope that helps,

Domenico

Re: Snapdrive VSS hardware provider not working

Hi,

 

i'm also in front of this error message, trying to backup an HyperV cluster with Veeam 8 :

 

Snapdrive is creating the snapshot, and is finishing with this event :

GetTargetLunInfo succeeded.

Storage System Name = vs-mutu-san-win-1
lunPath = /vol/hvr3exc1/mutu_exc1
Snapshot copy Name = {258c7671-6e0a-4470-9a85-9ca16b2ce96a}

 

but just after that i've got an error :

CreateTargetLun failed.

Storage System Name = vs-mutu-san-win-1
lunPath = /vol/hvr3exc1/mutu_exc1
Snapshot copy Name = {258c7671-6e0a-4470-9a85-9ca16b2ce96a}
Error code = 0xc00410d1
Error description = The clone creation operation failed. The volume name 'sdw_cl_hvr3exc1_0' exists already.

 

Veeam is telling me that this is a snapdrive error, so i must see with Netapp Smiley Happy and of course Netapp is saying here that it is a Veeam backup error ...

 

Whats next ?

Hi there.

 

I finally solve this error.

 

I was using a Snapdrive 7.1 (also tried 7.11)  with a clustered ontap 8.2.1 P2.

 

The snapshots are working with the MMC interface but doesnt work with command line tools like diskshadow to do backups.

 

I went back to Snapdrive 7.03 and all went fine after that : command line tools, and Veeam backups (nearly fine).

Re: Snapdrive VSS hardware provider not working

It is fixed in the latest version of Snapdrive - 7.1.3P3
