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 

smit clstop 

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 

cl_convert

 utility automatically updates the HACMP ODM object 

classes to the 4.3 version.

6. Reboot Node A.

7. Start the HACMP for AIX software on Node A using the 

smit clstart

 

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 

clverify

 utility.

11.Complete a test phase on the cluster before putting it into production.

The cluster topology is comprised of the following components:

  • The cluster definition

  • The cluster nodes

  • The network adapters 

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 

/etc/inittab

 and 

/etc/rc.net

 exist as specified in Appendix 

A of the 

HACMP for AIX, Version 4.3: Installation Guide, SC23-4278, 

before rebooting the node.
