Powering Up a New System

The procedures for powering up a system vary depending on the operating system and cluster management software that

are installed.

Powering Up a System with No Operating System Installed

Use the following procedure to power up a system that does not have an operating system installed and was not factory

integrated:

Note:

You must install an operating system and cluster management software on a system that ships without an operating

system installed before the system will be an operational cluster. Before attempting to boot the system, insert a DVD into

a USB DVD drive attached to the headnode or configure the headnode for network installation to install your desired

software on the system.

1. Verify that the power cords are connected to the rear of the system and the site power source.

2. Move the system enable switch on the rear of the enclosure to the ON position

Note:

The system enable switch applies power to all internal trays and switches. The headnode (located in the top

tray) is the only node that is configured to power-on automatically. The compute nodes do not power-on automatically;

you must start them manually with a cluster manager or IPMI if the operating system you install supports it.

3. Install the desired operating system and cluster management software on the headnode. Then, install the desired

images on the compute nodes.

Powering Up a System with Only the Linux OS Installed

Use the following procedure to power up a system that has the Linux OS installed but was not factory integrated:

1. Verify that the power cords are connected to the rear of the system and the site power source.

2. Move the system enable switch on the rear of the enclosure to the ON position

Note:

The system enable switch applies power to all internal trays and switches. The headnode (located in the top

tray) is the only node that is configured to power-on automatically. The compute nodes do not power-on automatically;

you must start them manually with the

ipmitool

command.

3. Power up the compute nodes using the

ipmitool

command from the headnode:

ipmitool -I lanplus -H [

node_bmc_ipaddr

] -U admin -P admin power on

For example, the following command powers up compute node 1:

ipmitool -I lanplus -H 10.0.40.1-U admin -P admin power on

Note:

You must install cluster management software and load your own compute node images to make the system an

operational cluster.
