Managing HP Serviceguard for Linux, Tenth Edition, September 2012

5. Distribute your changes to all nodes:
cmapplyconf -v -P pkg1.conf
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 the package configuration while the cluster
is not running. Use the same steps as in “Reconfiguring a Package on a Running Cluster
”.
Adding a Package to a Running Cluster
You can create a new package and add it to the cluster configuration while the cluster
is up and while other packages are running. The number of packages you can add is
subject to the value of MAX_CONFIGURED_PACKAGES in the cluster configuration file.
To create the package, follow the steps in the chapter Chapter 6: “Configuring Packages
and Their Services ” (page 199). Then use a command such as the following to verify the
configuration of the newly created pkg1 on a running cluster:
cmcheckconf -P $SGCONF/pkg1/pkg1conf.conf
Use a command such as the following to distribute the new package configuration to all
nodes in the cluster:
cmapplyconf -P $SGCONF/pkg1/pkg1conf.conf
If this is a legacy package, remember to copy the control script to the $SGCONF/pkg1
directory on all nodes that can run the package.
Deleting a Package from a Running Cluster
Serviceguard will not allow you to delete a package if any other package is dependent
on it. To check for dependencies, use cmviewcl -v -l <package>. System multi-node
packages cannot be deleted from a running cluster.
You can use Serviceguard Manager to delete the package.
On the Serviceguard command line, you can (in most cases) delete a package from all
cluster nodes by using the cmdeleteconf command. This removes the package
information from the binary configuration file on all the nodes in the cluster. The command
can only be executed when the package is down; the cluster can be up.
The following example halts the failover package mypkg and removes the package
configuration from the cluster:
cmhaltpkg mypkg cmdeleteconf -p mypkg
The command prompts for a verification before deleting the files unless you use the -f
option. The directory $SGCONF/mypkg is not deleted by this command.
