HP Serviceguard for Linux Version A.11.19 Release Notes, October 2009

NOTE: This and the following figures are from a use case in which the starting point
of the upgrade was Serviceguard A.11.14.02 and Red Hat AS 2.1, and the rolling upgrade
was to Serviceguard A.11.15.02 and Red Hat EL3. This is for illustration only; the
upgrade process has not changed since.

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 1-2.
