not indicate a failure unless a network component is plugged into that port on the
switch.
If necessary, see Chapter 10 (page 155) for information about troubleshooting
problems you might encounter during the discovery process.
Example 3-4 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 76) if the hardware
configuration does not contain HP ProLiant DL140 and DL145 hardware models.
3.6.2 Discovering Hardware Configurations With Server Blades and More Than
One Enclosure
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 more than one c3000 or c7000
enclosure is a multiple-step process. First, because the hardware configuration contain at least
one external ProCurve switch, the switch or switches are discovered, which activates the
administration network. Next, you perform hardware preparation tasks such as setting up
passwords and making BIOS settings. Lastly, the enclosures and nodes are discovered.
Complete these tasks in the following order:
1. “Discover Switches” (page 69)
2. “Set the Onboard Administrator Password and Make BIOS Settings” (page 70)
3. “Discover All Nodes and Enclosures” (page 71)
3.6.2.1 Discover Switches
Follow this procedure to discover 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.
