RE: [Linux-cluster] Queston about rh cluster suite 3



The iLO port is neither, it is a management port. Pretty easy to use, just
look up fence_ilo for the options. Basically the "agent" issues some telnet
commands to the iLO port and does a "power off" or a "power reset" command.
Not the fastest thing in the world but it works. I like the fibre switch
fenceing for it's speed and the fact that it forces manual intervention. If
something really bad is wrong, then the node won't keep trying to boot and
rejoin the cluster only to be fenced again.


Ok, after reading your original post, it seems you are using JUST cluster
services. GFS can fence the using iLO and fibre, NOT cluster services. That
said, if you install and configure GFS, you can use the GFS fencing methods
from within the cluster services by using the "gulm_bridge" fence device
type.

Using the standard RHEL3 cluster services your easiest route is prolly just
getting some power switches. I've used APC network controllable devices and
they work quite well. Just make sure you check the fencing module against the
firmware version so the agent works correctly.

Is it possible that we could use HP servers. But, how can I setup clusert.xml
to use iLO: serial, power switch??

Thanks.
