Reconfiguring a Package on a Running Cluster
Chapter 7 255
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. Only certain changes may be made while the package is
running.
To modify the package, use the following procedure (
pkg1 is used as an
example):
1. Halt the package if necessary:
# cmhaltpkg pkg1
See Table 7-3 to determine whether this step is needed.
2. If it is not already available, you can obtain a copy of the package's
ASCII configuration file by using the cmgetconf command,
specifying the package name.
# cmgetconf -P pkg1.ascii
3. Edit the ASCII package configuration file.
4. Verify your changes as follows:
# cmcheckconf -v -P pkg1.ascii
5. Distribute your changes to all nodes:
# cmapplyconf -v -P pkg1.ascii
6. Copy the package control script to all nodes that can run the
package.
