Perform this task only if the system requires additional RPMs from the HP XC distribution DVD; otherwise, omit this task.

By default, the HP XC system is installed with the software that is most appropriate for a high-performance cluster computer. Software that is more appropriate for a Linux workstation or time-sharing computer, such as much of the KDE and Gnome functionality, various web browsers, games, and so on, is available on the HP XC distribution DVD.

Proceed to the following sections for more information about installing additional software from the HP XC distribution DVD:

Enable HP XC To Run Serviceguard

This installation task is required if you intend to use HP Serviceguard as the availability tool to manage services that you configure with improved availability.

Use this procedure to mount the HP XC distribution DVD and install the RPM that enables Serviceguard to work on an HP XC system:

  1. Insert the HP XC distribution DVD into the DVD drive and mount it on the default location (the default location is the /media/cdrom directory): 

    # mount /dev/cdrom

  2. Change to the directory where the DVD is mounted:

    # cd /media/cdrom/HPC/extras/RPMS

  3. Determine the current version of the Serviceguard RPM, which is embedded in the RPM name:

    # ls | grep sg-avail

  4. Use the results obtained from the previous step to install the Serviceguard RPM:

    # rpm -ivh sg-avail-{version}.noarch.rpm

  5. Unmount the DVD:

    # cd
# umount /dev/cdrom

Run the SVA Installation Script to Install SVA

The HP Scalable Visualization Array (SVA) is a scalable visualization solution that brings the power of parallel computing to bear on many demanding visualization challenges. SVA is integrated with HP XC and shares a single interconnect with the compute nodes and a storage system.

The following are the key features of SVA:

  • Capturing and managing visualization-specific cluster information

  • Managing visualization resources and providing facilities for requesting and allocating resources for a job in a multi-user, multi-session environment

  • Providing display surface configuration tools to allow easy configuration of multi-panel displays

  • Providing launch tools, both generic and tailored to a specific application, that launch applications with appropriate environments and display surface configurations

  • Providing tools that extend serial applications to run in a clustered, multi-display environment

Installation Procedure

If SVA is required for your environment, use this procedure to install the SVA software:

NOTE: If you are configuring the /hptc_cluster file system on an SFS server, delay the SVA software installation until you configure and mount SFS file systems, including /hptc_cluster. The SVA installation script fails if /hptc_cluster is not available.

  1. Press Ctrl-Alt-F2 to open a Linux alternate console on the head node.

  2. Log in as root.

  3. Run the SVA installation script:

    # /opt/sva/kit_contents/2.1.0/install

    In the previous command, 2.1.0 reflects the SVA software version number; this number is incremented for every release.

    NOTE: The installation process takes several minutes to complete, and typically no command output appears if the head node is a server. When the RPM load is complete, the system prompt appears.

    If the head node is a workstation, you might see some messages about licensing, but you can ignore them.

  4. Use one of the following methods to exit the alternate console and return to the X server; the method you use depends upon the type of head node:

    • If the head node is a server rather than an HP workstation, log out of the alternate console:

      # logout

      Then, press Ctrl-Alt-F7 to return to the X server on the head node.

    • If the head node is an HP workstation, returning to the head node X server happens automatically. You then press Ctrl-Alt-F2 to return to the alternate console and log out. Press Ctrl-Alt-F7 and log in as root again.

Install Optional Linux RPMs

Follow this procedure to install additional, optional Linux RPMs from the HP XC distribution DVD:

  1. If the DVD is not already mounted, insert the installation DVD into the DVD drive and mount it on the default location (the default location is the /media/cdrom directory): 

    # mount /dev/cdrom

  2. Change to the following directory:

    # cd /media/cdrom/LNXHPC/RPMS

  3. Find the Linux RPM you want to install and issue the appropriate command to install it. Depending on the RPM you want to install, you will issue a command similar to the following:

    # rpm -ivh rpm_name_version.noarch.rpm

  4. Unmount the DVD:

    # cd
# umount /dev/cdrom
