Install HACMP 4.3 for AIX on Node A
5. After upgrading AIX and verifying that the disks are correctly configured,
install the HACMP 4.3 for AIX software on Node A. For a short description
of the filesets, please refer to
4.1.1, “First Time Installs” on page 93
or to
Chapter 8 of the
HACMP for AIX, Version 4.3: Installation Guide
,
SC23-4278.
6. The installation process automatically runs the
cl_convert
program. It
removes the current HACMP objects from
/etc/objrepos
and saves them
to HACMP.old. It creates new HACMP ODM object classes for Version 4.3
in
/etc/objrepos
.
7. Start the Version 4.3 software on Node A using the
smit clstart
fastpath.
After HACMP is running, start the previous version HACMP software on
Node B, if it is not still running. Check to ensure that the nodes
successfully join the cluster.
8. Repeat Steps 2 through 7 on Node B on remaining cluster nodes, one at a
time.
9. When the last node has been upgraded to both AIX 4.3.2 and HACMP 4.3,
the cluster install/upgrade process is complete.
Check Upgraded Configuration
10.If using tty devices, check that the tty device is configured as a serial
network using the
smit chgtty
fastpath.
11.In order to verify and synchronize the configuration (if desired), you must
have
/.rhosts files on cluster nodes. If they do not exist, create the /.rhosts
If upgrading from HACMP 4.1 for AIX, you must run the
cl_convert
utility
manually. Enter the following command:
/usr/sbin/cluster/conversion/cl_convert -v 4.1
Note
If the node running Version 4.3 fails while the cluster is in this state, the
surviving node running the previous version may not successfully mount
the file systems that were not properly unmounted due to Node A’s
failure.
Important
In a multi-node cluster, do not synchronize the node configuration or the
cluster topology until the last node has been upgraded.
