Hi,
why do you want to change your community string?
Check whether you have the following line in /etc/snmpdv3.conf -
 
smux     1.3.6.1.4.1.2.3.1.2.1.5      clsmuxpd_password # HACMP/ES for AIX clsmuxpd
 
And, check whether you have
 
/usr/es/sbin/cluster/clsmuxpd
 
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,
so change in snmpdv3.conf
COMMUNITY public    public     noAuthNoPriv 0.0.0.0     0.0.0.0         -
'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 0.0.0.0     0.0.0.0         -'
set.
