# 8.9. Disabling the Cluster Software

It may become necessary to temporarily disable the cluster software on a member system. For example, if a cluster system experiences a hardware failure, an administrator may want to reboot the system, but prevent it from rejoining the cluster to perform maintenance on the system.

Use the `/sbin/chkconfig` command to stop the member from joining the cluster at boot-up.

    /sbin/chkconfig --del clumanager

Once the issues with the disabled cluster member has been resolved, use the following command to allow it to rejoin the cluster:

    /sbin/chkconfig --add clumanager

You can then reboot the system for the changes to take effect or run the following command to restart cluster services:

    /sbin/service clumanager start
