HP Serviceguard Storage Management Suite A.03.02 Release Notes (March 2012)

7. Check the edited cluster configuration to verify if the cluster can be configured with existing
hardware and software resources using the cmcheckconf –C command, for example:
cmcheckconf –C cluster.conf
8. Correct any cluster configuration file errors, untill the output of the cmcheckconf –C command
displays no errors and warnings (as appropriate).
9. Apply the configuration using the cmapplyconf -C command, for example: cmapplyconf
–C cluster.conf
10. Bring the new node up using the cmrunnode command, for example: cmrunnode node3
11. To add the new node to the Modular Disk Group and Mount Point Packages, edit the package
ascii file configuration parameters to add the new node that the package will run on and the
activation and mount options:
• node_name : node1
• node_name : node2
• node_name : node3
• cfs_mount_point /cfsmnt01
• cfs_volume cvm_dg1 /lvol1
• cfs_activation_options: “node1=sw node2=sw node3=sw”
• cfs_mount_options: “node1= cluster node2= cluster node3=cluster”
12. Apply the ascii configuration file using the cmapplyconf command: cmapplyconf -P <
package.ascii >
13. Run the package on the newly added node using the cmrunpkg command: cmrunpkg -n
node3 <package_name>
14. Run the cmviewcl -v -p <package_name> command to check the status of the package.
15. Make changes to the application package configuration that depends on the mount point
/cfsmnt01, especially node name changes. Re-apply the package configuration, provided
the output of Step 14 is OK.
16. Repeat the steps 11 through 15 to add the new node to each of the Modular Disk Group and
Mount Point Packages.
Removing a Node from a CFS Cluster
The following example illustrates how you would remove one node (node2) from a cluster consisting
of two CFS nodes (node1 and node2):
1. Disable AUTOSTART_CMCLD in /etc/rc.config.d/cmcluster on node2:
In /etc/rc.config.d/cmcluster, set AUTO_START_CMCLD=0
2. Halt node2:
cmhaltnode -f node2
3. Delete node2 from all of the application packages. Edit all application package configuration
files and remove node2 from the package configuration. Re-apply the package configuration:
cmapplyconf -f -P app-pkg-config-file
4. To delete the node from the Modular Disk Group and Mount Point Packages, edit the package
configuration file and remove the node that is being deleted:
• node_name : node1
• cfs_activation_options : “node1=sw”
• cfs_mount_options : “node1= cluster”
