[Linux-cluster] SNMP support with IBM Blade Center Fence Agent

Hi all,

I have a question related to fence agents and SNMP alarms.

Fence Agent can fail to fence the failed node for various reason; e.g. with
my bladecenter fencing agent, I sometimes get message saying bladecenter
fencing failed because of timeout or fence device IP address/user
credentials are incorrect.

In such a situation is it possible to generate SNMP trap?

My cluster config file looks like below and in my case if bladecenter
fencing fails, manual fencing kicks in and requires user to do
fence_ack_manual, for this user must at least be notified via SNMP (or any
other mechanism?) to intervene  -

  <clusternodes>
    <clusternode name="blade2" nodeid="2" votes="1">
      <fence>
        <method name="1">
          <device blade="2" name="BladeCenterFencing"/>
        </method>
        <method name="2">
          <device name="ManualFencing" nodename="blade2"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="blade1" nodeid="1" votes="1">
      <fence>
        <method name="1">
          <device blade="1" name="BladeCenterFencing"/>
        </method>
        <method name="2">
          <device name="ManualFencing" nodename="blade1"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>
  <cman expected_votes="1" two_node="1"/>
  <fencedevices>
    <fencedevice agent="fence_bladecenter" ipaddr="blade-mm.com"
login="USERID" name="BladeCenterFencing" passwd="PASSW0RD"/>
    <fencedevice agent="fence_manual" name="ManualFencing"/>
  </fencedevices>

Thanks,
Parvez
