17.5 Configuration Files

You should never modify configuration files directly, unless you are directed to do so by a documented procedure or Novell Support.

The cluster configuration file is /etc/opt/novell/ncs/clstrlib.conf.

The cluster configuration for a specific node is /etc/opt/novell/ncs/<nodename>.

The cluster node numbers are found in the /var/opt/novell/ncs/gipc.conf file.

The Novell Cluster Services reboot behavior after shutting down a node conforms to the kernel panic setting for the Linux operating system. By default the kernel panic setting is set for no reboot after a node shutdown. You can use directive kernel.panic in the /etc/sysctl.conf file to allow an automatic reboot and to specify the number of seconds to delay the reboot. See Section 8.9, Configuring the Cluster Node Reboot Behavior.

If you use Device Mapper Multipath for devices, ensure that you modify the settings in the /etc/modprobe.conf.local file and the /etc/multipath.conf file, so that multipath I/O works correctly for Novell Cluster Services cluster resource fail over and fail back. See Section 4.10, Multipath I/O Configuration Requirements.
