Pinned topic clstat won't show cluster status

‏2010-09-23T21:20:43Z |
New install of PowerHA 6.1. When I run clstat I get the following:
Failed retrieving cluster information.

There are a number of possible causes:
clinfoES or snmpd subsystems are not active.
snmp is unresponsive.
snmp is not configured correctly.
Cluster services are not active on any nodes.

Refer to the HACMP Administration Guide for more information.

clinfoES is running:
Subsystem Group PID Status
clinfoES cluster 7405588 active

Ran sync and verify - no errors. Nodes will come up, RG's come active - everything is good except clstat won't work. Never heard of having to configure snmp to get it to work, plus since it says clinfoES OR snmpd and clinfoES is running, I assume clstat should work.

Any idea why clstat won't work in a properly configured cluster?

    Hi,

    I got similar problem on 5.5 and I've found this solution in /usr/es/sbin/cluster/README5.5.0.UPDATE:

    =====================================================================
    o APAR IZ41204: Enabling Internet MIB tree for clstat or cldump to work
    =====================================================================

    clstat or cldump will not start if the internet MIB tree is not
    enabled in snmpdv3.conf file. This behavior is usually seen in
    AIX 6.1 onwards where this internet MIB entry was intentionally
    disabled as a security issue. This internet MIB entry is required to
    view/resolve risc6000clsmuxpd (1.3.6.1.4.1.2.3.1.2.1.5) MIB sub tree
    which is used by clstat or cldump functionality.

    There are two ways to enable this MIB sub tree(risc6000clsmuxpd) they
    are:

    1) Enable the main internet MIB entry by adding this line in
    /etc/snmpdv3.conf file
    VACM_VIEW defaultView internet - included -
    But doing so is not advisable as it unlocks the entire MIB tree

    2) Enable only the MIB sub tree for risc6000clsmuxpd without enabling
    the main MIB tree by adding this line in /etc/snmpdv3.conf file
    VACM_VIEW defaultView 1.3.6.1.4.1.2.3.1.2.1.5 - included -

    Note: After enabling the MIB entry above snmp daemon must be
    restarted with the following commands as shown below:
    1) stopsrc -s snmpd
    2) startsrc -s snmpd
    After snmp is restarted leave the daemon running for about two
    minutes before attempting to start clstat or cldump.
