Managing Serviceguard Sixteenth Edition, March 2009

NOTE: The cmmigratepkg command requires Perl version 5.8.3 or higher on the
system on which you run the command. It should already be on the system as part of
the HP-UX base product.
Reconfiguring a Package on a Running Cluster
You can reconfigure a package while the cluster is running, and in some cases you can
reconfigure the package while the package itself is running. You can do this in
Serviceguard Manager (for legacy packages), or use Serviceguard commands.
To modify the package with Serviceguard commands, use the following procedure
(pkg1 is used as an example):
1. Halt the package if necessary:
cmhaltpkg pkg1
See “Allowable Package States During Reconfiguration ” (page 352) to determine
whether this step is needed.
2. If it is not already available, you can obtain a copy of the package's configuration
file by using the cmgetconf command, specifying the package name.
cmgetconf -p pkg1 pkg1.conf
3. Edit the package configuration file.
IMPORTANT: Restrictions on package names, dependency names, and service
names have become more stringent as of A.11.18. Packages that have or contain
names that do not conform to the new rules (spelled out under package_name
(page 262)) will continue to run, but if you reconfigure these packages, you will
need to change the names that do not conform; cmcheckconf and cmapplyconf
will enforce the new rules.
4. Verify your changes as follows:
cmcheckconf -v -P pkg1.conf
5. Distribute your changes to all nodes:
cmapplyconf -v -P pkg1.ascii
6. If this is a legacy package, copy the package control script to all nodes that can run
the package.
Reconfiguring a Package on a Halted Cluster
You can also make permanent changes in package configuration while the cluster is
not running. Use the same steps as in “Reconfiguring a Package on a Running Cluster
” (page 350).
