2. If you wish to save your cluster configuration, see the chapter Saving and
Restoring Cluster Configurations in the HACMP for AIX, Version 4.3:
Administration Guide, SC23-4279.
3. Commit your current HACMP for AIX software on all nodes.
4. Shut down one node (gracefully with takeover) using the
fastpath. For this example, shut down Node A. Node B will take over Node
A's resources and make them available to clients.
See the chapter "Starting and Stopping Cluster Services" in the HACMP
for AIX, Version 4.3: Administration Guide, SC23-4279, for more
information on stopping cluster services.
5. Install HACMP for AIX Version 4.3. See Chapter 8 of the HACMP for AIX,
Version 4.3: Installation Guide , SC23-4278, starting with the section
"Installation Choices", for instructions.
The
classes to the 4.3 version.
If IP address swapping is being used on this node, that is, a boot
address is defined for this node, check to ensure that the HACMP
changes to
A of the HACMP for AIX, Version 4.3: Installation Guide , SC23-4278,
before rebooting the node.
6. Reboot Node A.
7. Start the HACMP for AIX software on Node A using the
fastpath and verify that Node A successfully joins the cluster.
8. Repeat Steps 3 through 7 on remaining cluster nodes, one at a time.
9. After all nodes have been upgraded to HACMP Version 4.3, synchronize
the node configuration and the cluster topology from Node A to all nodes.
10.Verify the cluster topology on all nodes using the
11.Complete a test phase on the cluster before putting it into production.

4.2 Defining Cluster Topology

The cluster topology is comprised of the following components:
• The cluster definition
• The cluster nodes
• The network adapters
