Error description

  • When operating on a system where the IPv6 loopback
    address ::1 is a valid address for localhost, the
    clstrmgrES daemon may be unable to connect to the
    SNMP daemon.
    
    The following will repeat in clstrmgr.debug:
    
      ConnectToSnmp(): called, smuxFd is -1, retry count 0
      ConnectToSnmp: smux_init returned 17
      smuxFd is set in wrFds, try smux_simple_open
      smux_simple_open ok, try smux_register()
    
    
    In snmpdv3.log, the IPv6 loopback will be seen:
    
      Accepted new SMUX inet connection from ::1
    
    but snmpd will not be able to provide cluster status.
    

Local fix

  • Add this line of text to /etc/snmpdv3.conf:
    
    smux  1.3.6.1.4.1.2.3.1.2.1.5 clsmuxpd_password ::1 128
    

Problem summary

  • Customer is forced to re-start the PowerHA cluster
    which in turn will stop all the running services.
    

Problem conclusion

  • Code changes will allow peer to connect using IPv6 loopback
    address (::1) if no address or netmask is specified for
    an entry in the snmpd.conf or snmpdv3.conf file.
    

Temporary fix
