HP XC System Software Installation Guide Version 4.0

4 Discovering Hardware Components
The next step in the configuration process is to discover all system (hardware) components. In
addition to configuring the system topology by discovering all hardware components, the
discover command also configures the administration network and interconnect and populates
the configuration and management database (CMDB).
See Table 4-1 (page 63) to prepare the information you will be asked to supply during the
discovery process.
The discover process differs if HP server blades and enclosures are present in the hardware
configuration, how many enclosures are present in the hardware configuration, and if you are
configuring compute nodes that are not yet present but you plan to add in the future.
To discover your hardware components, follow the steps described in one of the following
sections:
• “Discovering Non-Blade Server Hardware Configurations” (page 64)
• “Discovering Hardware Configurations with Server Blades and More Than One Enclosure”
(page 68)
• “Discovering Hardware Configurations with Server Blades and a Single Enclosure” (page 72)
• “Discovering Hardware Configurations to Plan for Future Compute Node Expansion”
(page 73)
4.1 Preparing to Answer Discovery Questions
Table 4-1 describes the information required by the discover command. You can omit some
questions in the discovery process if you provide the related keyword and value on the discover
command line.
Table 4-1 Information Required by the discover Command
Description and User ActionItem
Enter the total number of nodes in the system configuration that are to be discovered
at this time. Make sure the number you enter includes the head node and all compute
nodes.
You are not prompted for this information if you are discovering a multi-region,
large-scale system.
If you specify the --enclosurebased option on the discover command line,
you are not prompted for this information.
You can include the nodes= keyword and value on the discover command line
to omit this question during the discovery process.
Total number of nodes in this
cluster
Enter the number of workstation nodes in the hardware configuration. Workstations
do not have console ports.
There is no default response, and a response is required. Enter 0 (zero) if the system
does not contain workstations.
You are not be prompted for this information if you are discovering a multi-region,
large-scale system.
If you specify the --enclosurebased option on the discover command line,
you are not prompted for this information.
You can include the ws= keyword on the discover command line to omit this
question during the discovery process.
