HACMP Installation and Cluster Definition 99
file on Node A using the following command:
/usr/sbin/cluster/utilities/cllsif -x >> /.rhosts
This command will append information to the /.rhosts file instead of
overwriting it. Then, you can ftp this file to the other nodes as necessary.
12.Verify the cluster topology on all nodes using the
clverify utility.
13.Check that custom event scripts are properly installed.
14.Synchronize the node configuration and the cluster topology from Node A
to all nodes (this step is optional).
15.It is recommended that you test the upgraded cluster to ensure proper
behavior.
Client-only Migration
If you are migrating from an HACMP 4.1 for AIX through HACMP 4.2 for AIX
server node to a client-only node running Version 4.3, first remove the
existing server portion of HACMP. If, after upgrading AIX, you install the
cluster.base.client.* filesets on a node running an earlier version of HACMP
for AIX without de-installing the server, the results are unpredictable.
To determine if there is a mismatch between the HACMP client and server
software installed on a node, issue the following command to list the installed
software:
lslpp -L "cluster*"
Examine the list and make sure that all cluster filesets are at 4.3.0.
If you determine that there is a mismatch between the client and server,
de-install the server and then repeat the installation of the client software.
In case the node was just a client before, you only have to install the
cluster.base.client.* filesets after it has been migrated to AIX Version 4.3.2.
Again, please check whether the installation succeeded by issuing the
command:
lslpp -L "cluster*"
4.1.2.2 Upgrading from Version 4.2.2 on AIX 4.3.2 to HACMP Version 4.3
The following steps describe upgrading from Version 4.2.2 on AIX 4.3.2 to
HACMP Version 4.3:
1. If your cluster is currently running Version 4.2.2 of the HACMP software on
AIX Version 4.3.2, you should upgrade your cluster configuration to
HACMP 4.3 for AIX.
