Reconfiguring a Package
Chapter 7310
Reconfiguring a Package
The process of reconfiguration of a package is somewhat like the basic
configuration described in Chapter 6. Refer to that chapter for details on
the configuration process.
The cluster can be either halted or running during package
reconfiguration. The types of changes that can be made and the times
when they take effect depend on whether the package is running or not.
Reconfiguring a Package on a Halted Cluster
You can also make permanent changes in package configuration while
the cluster is not running. Use the following steps:
• On one node, reconfigure the package as described earlier in this
chapter. You can do this by using Serviceguard Manager or by editing
the package ASCII file.
• Edit the package control script directly if not in Serviceguard’s
guided mode (in guided mode, Serviceguard manager does it
automatically at reconfiguration). Any changes in service names will
also require changes in the package configuration file.
• Click the Apply button in Serviceguard Manager, or enter
cmapplyconf on the command line. This copies the binary cluster
configuration file to all nodes. On the command line, use the -P
option, specifying the package to be changed; do not use the -C
option. This file overwrites any previous version of the binary cluster
configuration file.
• Copy the modified control script to all nodes that can run the
package. (Done automatically in Serviceguard Manager as part of
Apply.)
• Use the Serviceguard Manager Run Cluster command, or enter
cmruncl on the command line to start the cluster on all nodes or on a
subset of nodes, as desired. The package will start up as nodes come
online.
