ANS8002I Highest return code was 0.

As for the clients, set it to 4, unless you want to limit the number of drives 
that it can have. For example, you may want to limit your test node to 1, but 
your production node should have access to all four, if it needs them.

Ex:
ANS8000I Server command: 'q node unxp f=d'

                     Node Name: UNXP
                      Platform: AIX
               Client OS Level: 4.3
                Client Version: Version 4, Release 2, Level 2.1
            Policy Domain Name: NISA_DOM
            Keep Mount Point?: No

  Maximum Mount Points Allowed: 6
        Auto Filespace Rename : No
