Which RedHat OS do you have 4,5,6?

Are you looking for the graphical or command line?

Graphical, you would access the GUI Cluster manager from and on the active node and delete the passive node.

Hi Arnold,

It's RHEL 5. I'm looking for CLI commands.

5.5.3.1. Removing a Member from a Cluster at the Command-Line
clusvcadm -r cluster_service_name -m cluster_node_name
Transfer all from the node you want to remove first
Stop all cluster related services on the node you want to remove
Disable the cluster related services from starting using chkconfig servicename off
Now to remove node
ccs_tool delnode cluster_node_name

Oops, how important is the tested part of your question as it relates to the command line described above?
Used the GUI to perform the setup/adjustments.

I've had the documentation, but from my experience not sure the documentation covers everything, that's why I asked for experience.

Thing is I have to do it on production with no GUI.

As long as the production system have the graphical libraries installed, you could ssh -X user@production
And the send the GUI interface through the X11 tunnel of the sash connection back to the X server on the system from which you initiate a connection.

Thanks arnold, but situation is much complicated. I have no X installed and cannot switch runlevels due permission issues.

I have to use what I have now, the CLI.

I'm not talking about changing run levels on the production system.  How are you accessingtheoroduction system to effect the changes? Are you on console, are are you remoting in using ssh?

The ccs_tool have -c sourced isle -o outputfile delnode nodetoremove that you can test by copying the current cluster.conf to another location and then run the command  using the different location such that the live cluster.conf is not altered.  Unfortunately it sounds that you do not have a test environment where you can test this.

ccs_tool help


Note that "create" on its own will not create a valid configuration file.
Fence agents and nodes will need to be added to it before handing it over
to cman.

eg:
  ccs_tool create MyCluster
  ccs_tool addfence apc fence_apc ipaddr=apc.domain.net user=apc password=apc
  ccs_tool addnode node1 -n 1 -f apc port=1
  ccs_tool addnode node2 -n 2 -f apc port=2
  ccs_tool addnode node3 -n 3 -f apc port=3
  ccs_tool addnode node4 -n 4 -f apc port=4



instead of addnode, you would use delnode and the node will be removed from the cluster.conf. file

Test this where cluster is not running as a test to see whether changes to the cluster.conf will be done.
