It failed to mount. Could you try to mount it manually using the SnapDrive?   -Wei

Re: Backup Verification Error with SME 6.0 against an Exchange 2010

Hi,

I saw you were having 'System.OutOfMemoryException' errors, this is a windows problem, Its a problem with VSS.

There is a patch for this from Microsoft (8MB approx), which resolve this problem.

Cheers

Re: Backup Verification Error with SME 6.0 against an Exchange 2010

Hi Lwei,

No I can't - so it's not a problem with SME but rather one with Snapdrive!

Re: Backup Verification Error with SME 6.0 against an Exchange 2010

Hi Moez,

Do you know the MS-KB-Number?

I know about some VSS-Bugs within Windows 2003 and Windows 2008 but are there still some with Windows 2008 R2? That would be a pity...

Greetings,

Philipp

Re: Backup Verification Error with SME 6.0 against an Exchange 2010

Hi Phillip,

Dont have it off head, i did a windows update .. it picked up a VSS update .. After that no more issues.

Let me see if i can get the KB from the customer site.

Re: Backup Verification Error with SME 6.0 against an Exchange 2010

Hi Philip,

Check the event viewer logs. What error do you see in them regarding SnapDrive. What is the eventid?

Thanks,

Bhavik

Re: Backup Verification Error with SME 6.0 against an Exchange 2010

Hi Bhavik,

I only see a warning from PartMgr within the System-Log that the DiskSignature of the Snapshot that should be mounted is the same like an existing this. I would say that's expected and can be ignored ;-)

After 7 Minutes I see the EventID 1116 from SnapDrive within the Application-Log that states:

"Failed to connect to LUN. VDS volume object for the LUN s/n 'C4iAWJVCMvUY' has not been found"

So I don't know what's up here and my local Netapp-Guru is dealing with more important issues at the moment... :-(

Best regards,

Philipp

Re: Backup Verification Error with SME 6.0 against an Exchange 2010

Hi Philip,

You might have checked this but is the VDS service ON? If not restart it, then restart the Snapdrive service and try doing the verification again.

Thanks,

Bhavik

Re: Backup Verification Error with SME 6.0 against an Exchange 2010

Hi Bhavik,

Restarting both services helped at least something.

Now I'm getting the Error-Message "RPC-Server not available" when connecting the Snapshot manually. (Source SnapDrive, EventID: 1116)

Nevertheless the mount itself failes :-(

Best regards,

Philipp
