the existing cluster nodes to the new node.

running on the node to be deleted.
2. Stop the cluster software on the node to be deleted by running the following commands at
that node in this order:
a. service rgmanager stop
b. service gfs stop, if you are using Red Hat GFS
c. service clvmd stop, if CLVM has been used to create clustered volumes
d. service cman stop
3. At the Cluster Configuration Tool (on one of the running members), delete the member as
follows:
a. If necessary, click the triangle icon to expand the Cluster Nodes property.
b. Select the cluster node to be deleted. At the bottom of the right frame (labeled
Properties), click the Delete Node button.
c. Clicking the Delete Node button causes a warning dialog box to be displayed requesting
confirmation of the deletion (Figure 5.6, “Confirm Deleting a Member”).
