HP XC System Software Installation Guide Version 4.0

The discover command turns off the console management facility (CMF) daemon.

If the CMF daemon is not running, a “FAILED” message is displayed. This message

is expected, and you can ignore it.

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 Section 4.6 (page 74) if the hardware configuration contains HP ProLiant

DL140 and DL145 hardware models.

• Proceed to Chapter 5 (page 77) if the hardware configuration does not contain HP

ProLiant DL140 and DL145 hardware models.

4.4 Discovering Hardware Configurations with Server Blades and a Single

Enclosure

Follow this procedure to discover configurations that have only one HP BladeSystem c3000 or

c7000 enclosure present in the hardware configuration.

When only one enclosure is present, you must include the --single option on the discover

command line and you are required to enter the MAC address of the OA. Hardware configurations

with one enclosure do not have any external ProCurve switches.

1. Go to the enclosure, and obtain the MAC address of the OA. The OA is the small LED panel

near the bottom of the enclosure. Write down this MAC address because you will be required

to provide it.

2. Log in as the root user on the head node.

3. Start a script to capture command output into a file. This step is optional, but HP recommends

doing so.

# script your_filename

4. Change to the following directory:

# cd /opt/hptc/config/sbin

5. Start the discovery process:

# ./discover --enclosurebased [--extended {contiguous|non-contiguous}] --single --verbose

IMPORTANT: When you discover nodes, you must include the --extended option on

the command line if the hardware configuration contains double density blade servers such

as the ProLiant BL2x220c. The --extended option is only valid when used in conjunction

with the --nodesonly option.

A ProLiant BL2x220c has two separate nodes for each server blade, which affects internal

node numbering. This means that a c7000 enclosure can have a maximum of 32 nodes per

enclosure compared to the maximum of 16 single density server blades. A c3000 enclosure

can have a maximum of 16 nodes per enclosure compared to the maximum of 8 single density

server blades.

See Section 3.1.2 (page 51) for a description of how the --extended option calculates the

internal node names based on the maximum number of nodes in an enclosure.

Command output is similar to the following:
