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:

Try disabling the ARP checking in the message layer; see the cludb man
page for more details.  It should be in 1.2.31 and later.
