  3.         Select the relevant NAS server, and then select the Edit icon.     
  4.      
  5.         On the General tab:     
  6.    
   
         
  •         Change the NAS server name.     
  •      
  •         Select SP Owner to transition from one SP to the other SP for this NAS server. For example, you may want to do this if you have an overloaded SP, and want to reduce the load by moving the server to the other SP.

  2.    
   
         
  •         Select the Interfaces & Routes sub-tab to add, change, delete, or verify NAS server interfaces, enable or disable IP packet reflect for the NAS server, or change the NAS server's preferred interfaces. Select an interface, and then select Show external routes for interfaces to access the per-interface routing table, where you can add, change, or delete the selected interface's routes for responding to client requests.

  1.         On the Naming Services tab, configure DNS and either configure the UNIX Directory Service (UDS) for the NAS server (LDAP or NIS) or use local files. Alternatively, you can use local files with a UDS. In this case, the system checks the local files first.DNS, LDAP/NIS, Local files

Notes:

 

 

The following rules apply to changing NAS server settings:   

         
  •         You cannot disable multiprotocol file sharing for a NAS server once a file system is created on that NAS server.     
  •      
  •         If you disable multiprotocol file sharing on a NAS server, the NAS server still has the NFS and SMB protocols enabled, but no longer supports simultaneously sharing NFS and SMB file systems.     
  •      
  •         You cannot disable DNS for:                
               
    •                  NAS servers that support multiprotocol file sharing.         
    •          
    •                  NAS servers that support SMB file sharing and that are joined to an Active Directory (AD).         
    •        
                  
  •      
  •         To reconfigure a NAS server that supports SMB-only or NFS-only file systems so that it supports multiprotocol (both types of file systems simultaneously), first enable a UNIX Directory Service and DNS server for that NAS server.
