Setting up Autostart Features

Automatic startup is the process in which each node individually joins a cluster. If a cluster already exists, the node attempts to join it; if no cluster is running, the node attempts to form a cluster consisting of all configured nodes. Automatic cluster start is the preferred way to start a cluster. No action is required by the system administrator. To enable automatic cluster start, set the flag AUTOSTART_CMCLD to 1 in the /etc/rc.config.d/cmcluster file; the node will then join the cluster at boot time.

In order to automate the startup of cluster nodes after a system boot, you must modify the /etc/rc.config.d/cmcluster file on each node. MC/LockManager provides this startup script to control the startup process:

#                       join it's CM cluster automatically when
#                       the system boots.
#                       If set to 0, the node will not attempt
#                       to join it's CM cluster.
