snapmanager for exchange problem

GUVNIJJAR

WE are using snapmanager for exchange V6.0.2.871, and we are occasionally now getting errors on our backups which are failing.   The exchange server we use is exchange 2007.   The error we get is linked to the volume shadow copy service and the reports logs the following error message :

Error in calling VSS API: Error code = 0x8004230f

Error description: VSS_E_UNEXPECTED_PROVIDER_ERROR

We restart the snapdrive service which then corrects the situation, the backup next time runs successfully.   The server is running on a windows 2008 service Pack 2 server.

We get these messages once a week now.   Any reason why. 

Also are we running the latest snapmanager for exchange server , or is there a latest one.

Based on my research, the error code 8004230f means: The shadow copy

provider had an unexpected error while trying to process the specified

operation. Generally this issue can be caused the following factors:

1. Certain VSS DLLs are not registered properly

2. There is a problem with shadow copy provider

I suggest we perform the followings to troubleshoot the issue:

Step 1: First please apply the latest VSS package (KB940349) on the server.

Download Link:

http://support.microsoft.com/kb/940349

Reboot the server for the package to take effect

Step 2:  Re-register the VSS related DLLs

==================

To do so, type the following commands at the command prompt. Press ENTER

after each command.

cd /d %windir%\system32

net stop vss

net stop swprv

regsvr32 ole32.dll

regsvr32 oleaut32.dll

regsvr32 vss_ps.dll

vssvc /register

regsvr32 /i swprv.dll

regsvr32 /i eventcls.dll

regsvr32 es.dll

regsvr32 stdprov.dll

regsvr32 vssui.dll

regsvr32 msxml.dll

regsvr32 msxml3.dll

regsvr32 msxml4.dll

Note: The last command may not run successfully.

Try Backup and see if the error still occurs.

Step 3. If the issue persists, go to the following registry key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\STORAGE\Volume]

Import this key for backup

Delete Key "VOLUME"

Reboot the system

This will recreate the "VOLUME" key

Hi GUVNIJJAR,

please run the configuration Wizard again. It will only re-write the configuration without changes.

Check the SM logs to see the time of the failure then check the Windows logs to see if anything else was going on at this time.

I've seen this when the OS is being backed up at the same time the SM job is running and VSS gets screwed or any other process

If it literally is happening once per week on the same day this will be your problem
