HP Lefthand VSS Provider Import Snapshot Error

Case [ID#00667058]

Hello,

i have a big Problem with my Hyper V 2012 R2 and Lefthand P4500 Environment .

My Backup Server is a 2012 R2 physical Server, Hyper-V Role is activated, HP Application Aware Snapshot (Hardware VSS Provider) installed (on Hyper V Hosts too) and he is a Offhost Backup Proxy.
The Hyper V Cluster contains two Hyper V Hosts with Windows Server 2012 R2. I also connected the CSV Luns over iSCSI to the Veeam Server (Offhost Proxy) but the Backup Jobs finish with:
"Unable to create snapshot LeftHand Networks VSS Provider on Hyper-V Offhost Backup Proxy (mode: Crash consistent). Details: Failed to import snapshot: Import snapshot task has failed. Vss error: '0x80042320' "

On the Storage CMC Console i see that one of the Hyper V Server creates a Snapshot but it disappears when the Job Finishs with error.

"
Hope someone can help me.

Best Regards

Artur

Can you create a hardware VSS snapshot on the Hyper-V host itself and not on the off-host proxy server?

Artur, As far as I remember you have to configure access list to the Hyper-V server (acting as an off-host proxy) in HP storage management console. Basically, both production host and off-host proxy should have identical hardware VSS configuration, in this case there should not be any problems with snapshot creation.

In the HP management console did you give read-only access to the LUNs to your off-host proxy server? Did you configure off-host proxy in the same way as production host?

I would recommend checking VSS providers status via command line in that server. Additionally, while you're waiting take a look at Windows Event log, might be helpful.

So here is a Update to my Call..

Supporter made same Tests as before with same result... manually making HP VSS Provider Snapshots from Hyper-V works fine... with Veeam B&R its just not working ...

Call will be escelated to TK 2 ... hope this Guy will find the Issue...

Just found an old Article where someone had the same Issue with HP SAN ... but without Results ...

microsoft-hyper-v-f25/cant-create-hardware-snapshots-t14879.html

Dont know if this is an Veeam or an HP Issue but i have to say with Backup Exec the HP VSS Provider worked fine ... Maybe there is another mechanism but at this Call State (after 1 month now) iam very disappointed with the Veeam Support... because there is no Information where the Problem is located ...

Manual snapshot creating should work just fine, it seems like there is an issue with snapshot transfer, let's see what our T2 engineer will find out after reviewing the debug information.

So here is the final Update to my Call...

At first i want to thank Denis Bozhkov and Nicolay Sergeev the T2 engineers who found the solution for our Problem! Really great Job !

So here is the Problem:
In the CMC of the HP SAN the HyperV Servers where all in a Cluster Group which was assigned to the LUN´s. We made a new single entry for the Proxy Server and assigned the LUN´s too and thats the major issue. U have to add the Proxy Server to the Cluster Group and than the Direct SAN Backup will work fine with the Lefthand Hardware Provider. I know sounds very strange but its the solution !

Hope this gonna help someone with same Issue

If you add the off-host proxy to the same LUN, will you be able to set only read-access to the LUNs for the off-host proxy?
