The next step in the process is to configure the system. In this task, use the cluster_config utility to review default role assignments and modify the role assignments on all nodes in the system based on the size of the system (and other considerations, such as improved availability).

Depending upon the role assignments, the cluster_config utility prompts you to configure services (such as NAT, NIS, LVS) and prompts you to configure software components such as LSF (either LSF-HPC with SLURM or standard LSF), SLURM, and Nagios.

When you indicate that you are satisfied with the node role assignments and your configuration choices, the cluster_config utility builds the configuration and management database, starts all services on the head node and other service nodes, and creates the golden image from which all other nodes are replicated.

Follow this procedure to configure the system:

  1. Start a script to capture command output into a file; this step is optional, but HP recommends it:

    # script your_filename

  2. Change to the configuration directory:

    # cd /opt/hptc/config/sbin
    CAUTION: Make sure that no other terminal windows or shells are actively open in the /hptc_cluster directory. The cluster_config utility does not properly export the /hptc_cluster directory if any processes are using the directory when the cluster_config utility mounts the file system.

  3. Begin the cluster configuration process:

    # ./cluster_config
HP recommends that you back up the database before proceeding.
Do you want to back up the database? (yes/no) [y]: y

    The default location for the backup file is the /var/hptc/database directory.

  4. Proceed to “Task 8: Configure Availability Sets” to configure availability sets if you have installed and configured an availability tool (such as HP Serviceguard).

    Otherwise, proceed to “Task 9: Assign Node Roles”.
