Serviceguard Toolkits for Contrib User Guide Version A.12.00.00

9 Online Modification of the Toolkit package

In addition to the Online modification feature supported by Serviceguard, the online modification

feature of the toolkit allows you to modify some of the toolkit attribute values, while the toolkit

package is running. For more information about the list of attributes that support online modification

for a specific toolkit package, see the Attribute definition table in Configuring modular toolkit

packages of that Toolkit.

To perform online package modification:

1. While the package is running, retrieve the current package configuration values using the

command cmgetconf.

For example: # cmgetconf -p <<Toolkit_Package_Name>> <<Latest_Toolkit_Conf_File>>

2. Backup the latest configuration file using a copy utility. This allows you to refer to the previous

configuration values.

For example: # cp -p <<Latest_Toolkit_Conf_File>> <<Backup_Toolkit_Conf_File>>

3. Edit the <<Latest_Toolkit_Conf_File>> to modify the required attribute values.

4. Use the cmcheckconf command to verify the package configuration file.

For example: # cmcheckconf –P <<Latest_Toolkit_Conf_File>>

5. Use the cmapplyconf command to add the changes in the package configuration to the

Serviceguard cluster environment.

For example:# cmapplyconf –P <<Latest_Toolkit_Conf_File>>

NOTE: Information related to package reconfiguration is logged in the package log.
