Hotfix to address Etracks 932426 and 932446 - NetBackup (NBU) 6.0 and higher Snapshot backups or Backup Exec (BE) Remote Agent for Windows using the Storage Foundation for Windows (SFW) Volume snapshot copy service (VSS) snapshot provider fails [SFW 5.0].

Solution



This problem is caused by an Access Violation in VxCMD.dll. As a result, a backup job that requires the use of the SFW VSS snapshot technology will fail. Some examples of the Symantec backup applications that use this technology are the NetBackup Advanced Client Backup/NetBackup Snapshot Client Backup and Alternate Client Backup features.
In order to successfully perform a snapshot backup using the SFW VSS method, you need to apply the attached SFW 5.0 hotfix on all systems that such snapshot backups will be performed.
-------------------------------------------------------------------------
Specific information concerning this Hotfix: Windows 2003, SFW 5.0, and NBU 6.0 and higher or Backup Exec Remote Agent for Windows must be installed. Please make sure to select the correct fix for your server.

--------------------------------
Installation Procedure:
--------------------------------
1) Stop the "Veritas Vss Provider" service.
2) Stop the "Virtual Disk Service". (If a VDS error message, click OK and proceed with rest of the steps below, as this error, although not expected, it is not a concern. Symantec will address this issue in SFW/SFW-HA 5.0 RP1 and higher versions.)
3) For BE, stop the beremote service, "Backup Exec Remote Agent for Windows Systems" because it will have the vxcmd.dll loaded.
4) Take a backup of vxcmd.dll and vxvssprovider.exe present at this location:
<Veritas_Home>\Veritas Volume Manager 5.0
5) Place the privates at the above location based on the version of Windows (32 or 64 bit) running from the W2K3 or W2K3-64 folders.
6) Start the services stopped above.
VXCMD.DLL - 5.0.2.298
VXVSSPROVIDER.EXE - 5.0.31.297
Please Note: This fix has not been fully tested. It is recommended the fix be evaluated in a test environment before implementing it in your production environment. When the fix is incorporated into a Storage Foundation for Windows maintenance release, the resulting Hotfix or Service Pack must be installed as soon as possible. VERITAS Technical Services will notify you when the maintenance release (Hotfix or Service Pack) is available.
