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.

NOTE: The cluster_config utility processing time can take approximately ten minutes longer if it is run on a head node that is configured for improved availability with Serviceguard when the remaining nodes of the cluster are up and running.

After the entire system has been imaged and booted, you might need to re-run the cluster_config procedure to modify the node configuration. If the other node in the availability set with the head node is up and running, the Serviceguard daemons attempt to establish Serviceguard related communication with the node when they are restarted. Because the other node in the availability set is not actively participating in a Serviceguard cluster, it will not respond to the Serviceguard communication.

The Serviceguard software on the head node retries this communication until the communication times out. On a system running with the default Serviceguard availability configuration, the time out is approximately ten minutes.

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 doing so.

    # 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

  4. Decide whether you want to back up the database before proceeding:

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

    If you answer yes, the database backup file is stored in the /var/hptc/database directory.

  5. Proceed to one of the following sections:
