Anyone reading this know anything about dealing with redhat cluster? In particular use of the ccs_tool program?

sounds like you may be using an older cluster... we generally use the gui system-config-cluster.

redhat 5 with high performance cluster. I've tried to yum download a version of system-config-cluster, but you apparently need cluster, not hpc.

Do you know anything about the fence options?

[draakken.livejournal.com]

most of our clusters are RH enterprise 4.x, which is not HPC that I know of.

Fencing.

If the cluster decides that one of the machines should not be part of the cluster they need a way to ensure they don't provide services. We use ILO fencing. The cluster members connect to the ILO on the 'bad' machine and power cycle it.

Is ILO fencing a hardware thingie or a software thingie?

[draakken.livejournal.com]

both, its software that initiates a hardware interrupt for a power off, or reboot/reset.
