Symptoms

The Avamar Client cannot browse or back up SQL Server 2016 databases on a cluster.

When running a browse command from the command line, the following error appears: 

avsql Error <15125>: Specified path '<<SQL Listener\AlwaysOn Group name>>' does not exist or is not accessible

The failure occurs consistently for SQL Server 2016 clustered configurations that use AlwaysOn availability groups.


  

        
Cause

        

   The Avamar avsql Plug‑in cannot query the AlwaysOn group name by using PowerShell or internal .NET commands. This limitation prevents the plug‑in from resolving SQL Server listener paths during browse and backup operations.
  

  
 

        
Resolution

        

   
Upgrade the Avamar Server to a supported version that includes the fix.

   
    
    
  1. Verify the existing Avamar Server version.
    2. 
    
  2. Upgrade the Avamar Server to version 19.4.100‑124 or later.
    3. 
    
  3. Retry the SQL Server browse and backup operation.
    4. 
   

   
After the upgrade, the avsql Plug‑in correctly resolves the AlwaysOn group name and completes browse and backup operations successfully.
