HP Serviceguard Toolkit for NFS on Linux User Guide Version A.12.00.00

• Starts NFS service processes (including nfs.mon).
• Starts NFS file lock migration process if the lock migration feature is enabled.
To start the package, use either of the following commands:
• # cmrunpkg <package_name>
• # cmrunpkg -n <nodename> <pkgname>
Stopping the package
The Serviceguard package manager invokes the NFS toolkit script with stop as an input paramenter.
This in turn does the following:
• Unexports directory on the file system.
• Stops NFS server daemons, if lock migration is enabled.
• Stops NFS service processes (including nfs.mon).
• Stops NFS file lock migration process.
To stop the package, run the following command:
# cmhaltpkg <package_name>
Maintaining the package
When a Serviceguard package is in maintenance mode, it ensures the package will not failover
to an alternate node due to any failure in the application that is configured in the package.
To perform maintenance:
1. Enable the maintenance mode for the package using the cmmodpkg command.
cmmodpkg -m on <package-name>
2. Perform the maintenance actions.
For example, you can change the configuration of the application instance or install an
application patch.
NOTE: You can ignore the errors or warnings in the package log file when the package is
set to maintenance mode.
3. Disable the maintenance mode for the package using the cmmodpkg command.
cmmodpkg -m off <package-name>
NOTE: Ensure that an application instance is up and running before disabling the
maintenance mode.
Cluster verification feature for NFS toolkit
Cluster verification is a proactive mechanism to identify cluster inconsistencies that adversely affect
toolkit package failover to an adoptive node.
Advantages of Cluster verification
The important advantages of cluster verification are:
• To identify inconsistencies in Serviceguard and the NFS toolkit resources across package
nodes before you create and configure the NFS toolkit packages.
• To automate the process of validating certain attribute values specified in the package
configuration file.
