HP Serviceguard A.11.20- Managing Serviceguard Twentieth Edition, August 2011

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. External pre-scripts
3. Volume groups
4. File systems
5. Package IPs
6. External scripts
7. Services
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. Table 14 shows the required cluster state for many
kinds of changes.
