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

Figure 5 Running cluster with packages moved to node 1
Step 5. Move package back to original node
Move pkg2 back to its original node. Use the following commands:
# cmhaltpkg pkg2
# cmrunpkg -n node2 pkg2
# cmmodpkg -e pkg2
The cmmodpkg command re-enables switching of the package, which is disabled by the cmhaltpkg
command. The final running cluster is shown in Figure 1-6.
Figure 6 Running cluster after upgrades
Rolling upgrade from A.11.19.X to A.11.20.00
The following procedure describes how to perform the Rolling Upgrade from A.11.19.X to
A.11.20.00:
1. Enable global switching for packages running on node 1.
The cmmodpkg command enables switching of the package.
For example, #cmmodpkg -e pkg1
2. Halt first node.
Halt the node you want to upgrade. This results in the node's packages to start up on an
adoptive node. The Serviceguard daemon on node 1 is halted.
For example, # cmhaltnode -f node1
