Novell LINUX ENTERPRISE 11 - HIGH AVAILABILITY, Manual, Page: 111 / 298

11.2 Update/Installation
After preparing the cluster and backing up the files, you can start updating the cluster
nodes to the latest product version. Instead of running an update, you can also do a
fresh SUSE Linux Enterprise 11 installation on your cluster nodes.
Procedure 11.2 Updating to SUSE Linux Enterprise 11
1 On all cluster nodes, perform an update from SUSE Linux Enterprise Server 10
SP2 to SUSE Linux Enterprise Server 11. For information on how to update your
product, refer to the SUSE Linux Enterprise Server 11 Deployment Guide,
chapter Updating SUSE Linux Enterprise .
Conversely, you can also freshly install SUSE Linux Enterprise Server 11 on all
cluster nodes.
2 On all cluster nodes, install SUSE Linux Enterprise High Availability Extension
11 as add-on on top of SUSE Linux Enterprise Server. For detailed information,
see Section 3.1, “Installing the High Availability Extension” (page 23).
11.3 Data Conversion
After having installed SUSE Linux Enterprise Server 11 and the High Availability
Extension, you can start with the data conversion. The conversion script shipped with
the High Availability Extension has been set up with care, but it cannot handle all set-
ups in fully automatic mode. It alerts you of the changes it makes, but needs interaction
and decisions from your side. You need to know your cluster in detail—it is up to you
to verify that the changes are meaningful. The conversion script is located in
/usr/
lib/heartbeat
(or in
/usr/lib64/heartbeat
, if you are using a 64-bit sys-
tem).
NOTE: Executing Test Runs
To make yourself familiar with the conversion process, we highly recommend
that you test the conversion first (without making any changes). You can use
the same test directory to do repeated test runs, but you only need to copy
the files once.
