HP Serviceguard for Linux Base Version 12.00.00 Release Notes, May 2014

• Ensure that you run the cmupgrade tool on all the nodes that are part of the cluster.
• Ensure that the Jetty server and Java are installed on the nodes before you run the cmupgrade
tool. Also, ensure that java -version command displays the version greater than or equal
to 1.7.0 in the output.
To perform the rolling upgrade from A.11.20.X to A.12.00.00 using cmupgrade tool:
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. You can upgrade node as follows:
a. Export the SGMGR_ENV environment variable:
SGMGR_ENV=<replicated user password>
where, <replicated user password> is the password that you want to set for
Serviceguard Manager user.
For more information about how to create a replicated user, see “Installing HP
Serviceguard for Linux the traditional way”.
NOTE: Installation of Serviceguard Manager for Linux B.12.00.00 automatically creates
a user called sgmgr and password for this user is taken from the SGMGR_ENV environment
variable.
b. Upgrade node 1:
# cmupgrade [-a <automatic-installation-of-pre-requisites>] {-d
<mount-path-where-DVD-is-mounted>} {-j <jetty location>}
For more information, see cmupgrade (1m) manpage.
c. If you are upgrading to patch:
# cmupgrade {-d extracted_patch_location} {-j jetty-location}
IMPORTANT: Before you upgrade to the patch, ensure that HP Serviceguard for Linux
Base 12.00.00 is installed on your system.
4. Restart cluster on first node.
For example, # cmrunnode -n node1
Check that the node joins the cluster successfully, and if necessary, move packages back to
the node.
5. Repeat steps from 2 to 4 for all the nodes.
