3.4 Task 3: Run the cluster_prep Command to Prepare the System
The first step in the configuration process is to prepare the system by running the cluster_prep
command. This process sets up the node naming prefix, the number of nodes in the system, the
configuration and management database administrator's password, the external Ethernet
connection on the head node, starts the MySQL service, and initializes the configuration and
management database.
1. Begin this procedure as the root user on the head node.
2. Change to the following directory:
# cd /opt/hptc/config/sbin
3. Start the system preparation process by invoking the cluster_prep command. An
additional command line option is required if the hardware configuration contains HP server
blades and enclosures.
CommandHardware Configuration
# ./cluster_prep
Without HP server blades and enclosures
# ./cluster_prep --enclosurebased

Command output is similar to the following. Table 3-1 (page 56) describes each prompt and
provides information to help you with your answers.
IMPORTANT: Do not press Ctrl-c or Ctrl-d, enter the kill command, or use any other
abnormal termination method to terminate the cluster_prep utility.
If you terminate cluster_prep before it completes its processing, you must use the Kickstart
installation procedure to reinstall the head node.
The cluster_prep utility prepares the head node for the
automated discovery process. This utility is run during the initial
cluster configuration or any time your cluster is reconfigured.
If you reconfigure your cluster, you must run the discover
command after running the cluster_prep utility.
