I guess the redhat docs explains how to use system-config-cluster.

Hi ,
Sorry for replying in late, became busy with other work.
I have gone through the document you mentioned. I have already mounted the GFS on each node. I am building the guests on this GFS file system and all the nodes are zen hosts.
My question is, the file system will be available from each node but the guests will be only available from the node from where the xm create is being executed.
- Suppose the guests are in node1. Now if node1 gone down then all the
guests will go down too. But if the guests are enabled from all the
nodes then if node1 gone down, then still in the other nodes the guests
are running.
- That's why my first email is for that should I need to create any
service so that if any script is being set under the service and in
that script ,I can mention xm create create etc etc, to bring up the
guests in other node and so on.
So pl. advice me now what will be the best procedure to follow in the
above scenario which I mentioned.If you have GFS mounted on all the nodes, then you need to create your xen hosts on that shared GFS partition and then create virtual machine services to control(recovery,restart) the xen hosts. You can do that from Luci.This might help youParas.
Thanks again
