Issue:

 

 

From the Advanced Backup Configuration tab of the dashboard, an administrator can add the following supported NAS systems if at least one NDMP Accelerator node is deployed:   

         
  •          EMC Celerra, EMC Unity, or EMC VNX     
  •      
  •          EMC Isilon     
  •      
  •          NetApp filer     
  •      
  •          Oracle ZFS     
  •    
    This view also allows an administrator to edit or delete an existing connected NAS system.   
   
    Procedure   
         
  1.         From Advanced Backup Configuration > NAS page, click Add.     
  2.      
  3.         Select the NAS Type, Encoding Scheme, and NDMP Accelerator.     
  4.      
  5.         Type the NDMP Account Name, NDMP Account Password, and Avamar Account Name.     
  6.      
  7.         Click Save.     
  8.    
   
      Note   
   
      Only the following characters may be used in the NDMP account name: a-z       
        (lowercase), '.', '-', and '_'.       
        A green check mark indicates that the NDMP Account Password and Confirm       
        Password field match.
   
   
          
Expected results   
      After adding a NAS system, you can create a protection job for the new system with the Avamar Administrator GUI.     
     
      Some systems may report "Fail to load NAS data" error message after successfully adding NAS system     
     
      Newly added NAS system will not be displayed under Advanced Backup Configuration tab

    Since admin user on Avamar Accelerator does not have permission to read ndmp.cfg file, results will this issue 
                                                           

 

 

Resolution:

 

 

Work Around    

      Login to Avamar accelerator node using "admin" user account     
     
      Switch to root user  and run following commands to fix permission issue   

   

      #su -       
        Password: < enter root user password>       
       
        # cd /usr/local/avamar/var/       
        # chmod -R 750 <NAS filer host name>       
        # chgrp -R admin <NAS filer host name>
   

   

      Example:     
          

   

      # cd /usr/local/avamar/var/       
        # chmod -R 750 mynasserver       
        # chgrp -R admin mynasserver
