11.4 Performing Installation Actions Specific to HP XC
Follow this installation procedure:
1. Install the PBS server node (front-end node) first, using the installation script provided by
the software vendor, and specify the following values:
a. Accept the default value offered for the PBS_HOME directory, which is /var/spool/
PBS.
b. When prompted for the type of PBS installation, select: option 1 (Server, execution

c. If available, enter the license key during the interactive installation. Otherwise, you can
execute the script named /usr/pbs/etc/pbs_setlicense on the PBS server node
after the installation is complete. See Section 11.6 (page 161) for more information.

this installation to the remaining execution nodes, as described in Section 11.6 (page 161).
NOTE: You are not prompted for license information during installation of an execution
node.
a. When prompted for the type of PBS installation, select: option 2 (Execution only).
b. When you are prompted for the name of the PBS server node, provide an internally
resolvable name (such as n16 for the head node of a 16-node system), using the letter
n as a node-naming prefix.
c. Respond appropriately when the following installation script prompt appears:
Would you like to start PBS now?
• If you have finished the installation (no additional PBS clients to install), enter y
(yes) and initiate the software from the PBS server node manually, as described in
its user documentation. Proceed to Section 11.5 (page 160).
• If you are installing optional PBS client nodes, enter n (no) and proceed to step 3.
3. Install optional PBS clients, specifying the following values:

b. When you are prompted for the name of the PBS server node, provide an internally
resolvable name (such as n16 for the head node of a 16-node system), using the letter
