    why do you want to change your community string?
    Check whether you have the following line in /etc/snmpdv3.conf -
    smux      clsmuxpd_password # HACMP/ES for AIX clsmuxpd
    And, check whether you have
    up and running? (look at ps -ef)
    If yes, restart the HACMP/snmp/clinfo environment
    stopsrc -s clinfoES
    stopsrc -s clsmuxpdES
    stopsrc -s snmpd

    startsrc -s snmpd
    startsrc -s clsmuxpdES
    startsrc -s clinfoES
    and try again!
    If still no success, please come back and give a closer description of your problems.

    Hi again.

    should  first change the SNMP string before doing above.

    Also so I need to cbange he 'clsmuxpd_password' with the new string.

    so change in snmpdv3.conf
    COMMUNITY public    public     noAuthNoPriv         -
    'public' public' to whatever you want (same string for both!)
    Note that your snmp managers, e.g. tivoli (if any) should know the new name.
    Please leave the clsmuxpd password unchanged, until everything else works.
    We'll try to change it later.

    What I forgot to mention...
    ... HACMP uses the first community string it finds which is _not_ 'system' or 'private'. So, if you have multiple communities in your configuration, take care that the first one (after 'system' or 'private' if applicable) has
    'noAuthNoPriv         -'
