Re: DRAC5 fencing problem with Redhat 5.3 cluster

[Dan Hayes <dhayes501@xxxxxxxxx>]

For some reason, the last time I tried to post this, it didn't work (if it did, I apologize for the repeat), so I'm posting it again...



I have 8 Dell servers all loaded with Redhat 5.3.  The machines have an
external and internal IP address.  The cluster is configured on the
internal ip address.

The cluster appears to be working fine except for fencing.  I try to manually fence a node, but get a connection error
[root@w002 ~]# fence_node lb001.domain.com
agent "fence_drac5" reports: Unable to connect/login to fencing device

I
was able to get the fence_drac5 command to work directly by adding the
"-x" option for using SSH.  It says the connection times out, but it
does shut down the other machine
[root@w002 ~]# fence_drac5 -a 165.289.178.221 -l root -p pass -x lb001.domain.com
Connection timed out

Why
does the connection time out?  And how do I add the "-x" option to the
cluster.conf file so that the fencing agent can connect?

Here are my /etc/hosts and /etc/cluster/cluster.conf files.
