Removing LifeKeeper

You can uninstall LifeKeeper in a Linux environment via the command line by entering the following command.

/opt/LifeKeeper/bin/rmlk

This command uninstalls all the LifeKeeper packages and removes the directory /opt/LifeKeeper from the system. The command can be run with or without LifeKeeper running on the system. If the command is run with LifeKeeper running on all nodes in the cluster, then hierarchies are unextended and any comm paths are removed. This ensures that all remnants of the node on which the command was run are removed from the remaining nodes which effectively removes the node from the cluster. If LifeKeeper is not running at the time the command is executed, then the other nodes will have remnants remaining which may impact the running system.

This command takes 2 optional arguments:

• -j which removes any Java packages installed by LifeKeeper

• -l which remove all LifeKeeper licenses

Use this command carefully.

*Note: The periodic backup of the LifeKeeper configuration via the command lkbackup automatically archives the results in /opt/LifeKeeper/config/. Because the rmlk command will remove the /opt/LifeKeeper directory you may wish to back-up the archives before running the command.
