Managing HP Serviceguard A.11.20.10 for Linux, December 2012

7. If everything is working as expected, bring the package out of maintenance mode:
cmmodpkg -m off pkg1
8. Restart the package:
cmrunpkg pkg1
7.5.3.2 Excluding Modules in Partial-Startup Maintenance Mode
In the example above, we used cmrunpkg -m to run all the modules up to and including
package_ip, but none of those after it. But you might want to run the entire package apart from
the module whose components you are going to work on. In this case you can use the -e option:
cmrunpkg -e sg/service pkg1
This runs all the package's modules except the services module.
You can also use -e in combination with -m. This has the effect of starting all modules up to and
including the module identified by -m, except the module identified by -e. In this case the excluded
(-e) module must be earlier in the execution sequence (as listed near the top of the package's
configuration file) than the -m module. For example:
cmrunpkg -m sg/services -e sg/package_ip pkg1
NOTE: The full execution sequence for starting a package is:
1. The master control script itself
2. Persistent reservation
7.6 Reconfiguring a Cluster
You can reconfigure a cluster either when it is halted or while it is still running. Some operations
can only be done when the cluster is halted. The table that follows shows the required cluster state
for many kinds of changes.
