HP Serviceguard A.11.20.10 for Linux Release Notes, December 2012

Example
The following example shows a simple rolling upgrade on two nodes running one package each.
NOTE: This and the following figures are from a use case in which the starting point of the
upgrade was Serviceguard A.11.19 and Red Hat Enterprise Linux 5.7, and the rolling upgrade
was to Serviceguard A.11.20.00.
Figure 1 Running cluster before rolling upgrade
Step 1. Halt first node
Halt the first node, as follows
# cmhaltnode -f node1
This will cause Pkg1 to be halted cleanly and moved to node 2. The Serviceguard daemon on
node 1 is halted, and the result is shown in Figure 2.
Figure 2 Running cluster with packages moved to node 2
Step 2. Upgrade first node
Upgrade node1 new version of Serviceguard as shown in the figure.
