I have a cluster setup with 2 dell servers, dual ethernet heartbeats,
and a single 8-port APCMaster PDU switch. The cluster works except
for one issue. The cloned stonithd interface refuses to make a call to
the apcmaster to power down the node that's "dead". Reading through
the logs I can see that during setup the stonithd asks the
apcmastersnmp module to check it's hosts list and it returns the
correct hostnames "tpc-dal-prlores3 tpc-dal-tcfs2". However when the
time comes for it to actually use the device I get the following
message from stonithd refusing to actually kill the other node.

The stonith is configured as follows:
<clone id="fencing" >
<primitive class="stonith" id="apcstonith23" type="apcmastersnmp" >
<operations id="apcstonith23-operations" >
<op id="apcstonith23-op-monitor-15" interval="15"
name="monitor" start-delay="15" timeout="15" />
</operations>
<instance_attributes id="apcstonith23-instance_attributes" >
<nvpair id="nvpair-604e339f-a400-4b30-82c0-f046de0ed663"
name="ipaddr" value="172.20.1.23" />
<nvpair id="nvpair-ed611421-97a1-4091-a5cd-8159f1230096" name="port"
value="161" />
<nvpair id="nvpair-997431e2-ea78-4065-b835-f9149bbcb596"
name="community" value="private" />
</instance_attributes>
</primitive>
<meta_attributes id="fencing-meta_attributes" >
</meta_attributes>
</clone>
I can confirm the use of the stonith via the command "stonith -t
apcmastersnmp <params> tpc-dal-prlores3" and it'll switch off the
server.
Any help would be appreciated.
