HP XC System Software Installation Guide Version 3.2

7.2 Caveats
The following caveats apply to installing HP XC System Software on Red Hat Enterprise Linux:
• HP XC System Software has been tested and certified only on the interconnect types listed
in Table 7-1.
• The HP StorageWorks Scalable File Share (SFS) product is not supported.
• The OpenFabrics Enterprise Distribution (OFED) has not been qualified.
• The improved availability feature of HP XC System Software has not been certified.
• If you use the Red Hat up2date RPM update package to upgrade from WS EL4 Update 4
to a later update, do not select module-init-tools. Doing so removes the modules
package. The HP XC modulefiles_hptc package depends on the modules package.
7.3 Task 1: Prepare for the Installation
Complete the following tasks before you begin the installation process:
• Determine which node will be the head node.
The head node in an HP XC system is always the node connected to the highest port number
of any node on the Root Administration Switch and the Root Console Switch. For more
information, see the HP XC Hardware Preparation Guide.
• Prepare your responses to the Red Hat installation process.
The Red Hat installation process prompts you to supply responses for several parameters,
and you will supply the same responses to the HP XC cluster_prep utility after you
install the HP XC System Software. It is critical that you plan your responses and provide
the values that are appropriate to the HP XC system head node.
— host name
— IP address for the head node Ethernet connection to the external network
— gateway is the network gateway IP address for your site
— netmask is the network mask for the external network on the head node
— dns server is the IP address the DNS server at your site
See Table 3-1 (page 56) if you need more information to plan your responses.
7.4 Task 2: Install the Red Hat Software
Follow the instructions from Red Hat to install the Red Hat software on the head node. Table 7-2
lists the settings you must make during the installation process.
