HP Serviceguard A.11.20.00 for Linux Release Notes, August 2012

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.

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

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

4. Install authd rpm from the Linux Distribution DVD/Repository

For example, #rpm -i <authd rpm>

5. Upgrade node1.

The following examples show only the Serviceguard rpm. Generally, you also need to install

the following:

• cmsnmpd

• sgproviders

For example, Serviceguard rpm for Red Hat 5 x86_64

#rpm –Uvh serviceguard-A.11.20.00-0.rhel5.x86_64.rpm

• SGMgrPI

6. Restart Cluster on First Node.

For example, # cmrunnode node1

Check that the node joins the cluster successfully, and if necessary, move packages back to

the node.

7. Repeat steps from 2 to 6 for all the nodes.
