HP Serviceguard A.11.20.20 for Linux Release Notes, May 2013

Figure 6 Running cluster after upgrades
6.12 Rolling upgrade from A.11.19.X to A.11.20.20
The following procedure describes how to perform the Rolling upgrade from A.11.19.X to
A.11.20.20:
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
3. Uninstall sg_pidentd rpm.
CAUTION: Serviceguard commands will not work unless step 5 is complete. You cannot
change the cluster configuration files until the process of upgrade is complete on all nodes.
For example, #rpm -e --nodeps sg_pidentd-3.0.19-2
Note: This step is applicable only on Red Hat Enterprise Linux.
4. Install authd rpm from the Linux Distribution DVD or Repository
For example, #rpm -i <authd rpm>
Note: This step is applicable only on Red Hat Enterprise Linux.
5. Upgrade node1 to A.11.20.00 on Red Hat Enterprise Linux and A.11.20.10 on SUSE Linux
Enterprise Server.
The following examples show only the Serviceguard rpm. Generally, you also need to install
the following:
• cmsnmpd
• sgproviders
• serviceguard-xdc (on SUSE Linux Enterprise Server only)
For example, Serviceguard rpm for Red Hat 5 x86_64
#rpm –Uvh serviceguard-A.11.20.00-0.rhel5.x86_64.rpm
