[rhn-users] Red Hat Cluster Suite Question

[Greg Forte]

Please paste or attach your cluster.conf, and show the exact commands 
you're using when you start the "local cluster services" (not sure what 
you mean by "local" in this context) and when you "try manually moving 
the service".  Also, what are the primary IP addresses (configured in 
/etc/sysconfig/network-scripts/ifcfg-eth*).  I suspect that you are 
either trying to use a cluster service IP address that is not in the 
same subnet as the primary IP addresses, or else that you are trying to 
use one of the primary IP addresses as the cluster service IP address, 
but those are only guesses until I see all the info.

BTW, this sort of question is much more likely to get answered on the 
linux-cluster list:

https://www.redhat.com/mailman/listinfo/linux-cluster

I highly recommend you join it if you haven't already.

What we want to do is to create a two-node Active/Passive failover cluster for our mail store running Sun JES Messaging Server 6.1. The shared storage is on an EMC CLARiiON CX500 SAN.

I've assigned IP addresses on the same subnet to each of the NICs dedicated for the heartbeat link; both machines are able to ping each other through the heartbeat link. I've also connected both servers to APC PDUs and have verified that I can reboot one machine from the other using the clufence command.

Please check logs for details." When I checked the cluster.log file (I modified my syslog settings to log cluster messages to /var/log/cluster.log), I see the following messages:
