HP XC System Software Installation Guide Version 3.2

If necessary, see Chapter 12 (page 165) for information about troubleshooting
problems you might encounter during the discovery process.
Example 3-2 shows the unique command output for a large-scale system with two regions;
all other command output is similar to the previous example.

6. If the hardware configuration contains HP workstations and you installed SVA, turn on
power to the render and display workstations. Then, when prompted, turn off power to the
same nodes, leaving the head node power turned on.
7. If you captured the output of the discover command in a file (described in step 2), press
Ctrl-d to end the script session now.
This file is for your information only. Store this file in a directory where you keep
administrative data.
8. Do one of the following:
• Proceed to “Modify the Default Password for HP ProLiant DL140 and DL145 Hardware
Models” if the hardware configuration contains HP ProLiant DL140 and DL145 hardware
models.
• Proceed to “Task 6: Set Up the System Environment” (page 74) if the hardware
configuration does not contain HP ProLiant DL140 and DL145 hardware models.
3.6.2 Discovering Hardware Configurations With Server Blades and Enclosures
The HP XC System Software has been designed to communicate directly with the Onboard
Administrator on each enclosure. Thus, the discover command obtains the required
configuration information directly from the Onboard Administrator to automatically discover
all components in the hardware configuration.
Discovering hardware configurations with server blades and enclosures is a multiple-step process.
First, the switches are discovered, which activates the administration network. Next, you perform
hardware preparation tasks such as setting up passwords and making BIOS settings. Then, the
enclosures and nodes are discovered.
Complete these tasks in the following order:
1. “Discover Switches” (page 70)
2. “Set the Onboard Administrator Password and Make BIOS Settings” (page 71)
3. “Discover All Nodes and Enclosures” (page 72)
3.6.2.1 Discover Switches
Follow this procedure to discover the switches and activate the administration network. Before
you begin, you must have already returned the Onboard Administrator to its original
configuration and you must be logged in to the head node through the external network
connection.
