HP XC System Software Installation Guide Version 4.0

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. “Discovering Switches” (page 69)

2. “Setting the OA Password and Make BIOS Settings” (page 70)

3. “Discovering All Nodes and Enclosures” (page 70)

4.3.1 Discovering Switches

Follow this procedure to discover switches and activate the administration network. Before you

begin, you must have already returned the OA to its original configuration and you must be

logged in to the head node through the external network connection.

NOTE: The following procedure assumes that all enclosures have been physically set up and

populated with nodes, all components have been cabled together as described in the HP XC

Hardware Preparation Guide, you have prepared the head node and the non-blade server nodes

according to the instructions in the HP XC Hardware Preparation Guide, and the server blade head

node is installed with HP XC System Software.

1. Begin this procedure as the root user on the head node.

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

doing so.

# script your_filename

3. Change to the following directory:

# cd /opt/hptc/config/sbin

4. Discover the switches:

# ./discover --enclosurebased --network [--ic=AdminNet] --verbose

NOTE: The [--ic=AdminNet] option is required only if you are configuring the

interconnect on the administration network.

Command output looks similar to the following:

Discovery - XC Cluster version HP XC Vn.n time_stamp

Enter the MAC address of the switch the head node plugs into

in the format xx:xx:xx:xx:xx:xx : your_MAC_address

Please enter the Procurve switch Administrator password : your_password

Please re-enter password: your_password
