Reconfiguring a Cluster
Chapter 7366
cmquerycl -C clconfig.ascii -c cluster1 -n ftsys8 -n ftsys9
Step 3. Edit the file clconfig.ascii to check the information about the nodes
that remain in the cluster.
Step 4. Halt the node you are going to remove (ftsys10 in this example):
cmhaltnode -f -v ftsys10
Step 5. Verify the new configuration:
cmcheckconf -C clconfig.ascii
Step 6. From ftsys8 or ftsys9, apply the changes to the configuration and
distribute the new binary configuration file to all cluster nodes.:
cmapplyconf -C clconfig.ascii
NOTE If you are trying to remove an unreachable node on which many
packages are configured to run (especially if the packages use a large
number of EMS resources) you may see the following message:
The configuration change is too large to process while the
cluster is running.
Split the configuration change into multiple requests or halt
the cluster.
In this situation, you must halt the cluster to remove the node.
