Configuration and utilities 39

Remotely boot a host server blade to a virtual diskette image to perform a ROM upgrade or install

an OS.

Send alerts from iLO 2 Advanced regardless of the state of the host server blade.

Access advanced troubleshooting features provided by iLO 2 Advanced.

Launch a web browser, use SNMP alerting, and diagnose the server blade with HP SIM.

Configure static IP bay settings for the dedicated iLO 2 management NICs on each server blade in

an enclosure for faster deployment.

The server blade must be properly cabled for iLO 2 connectivity. Connect to the server blade with one of

the following methods:

Through an existing network (in the rack)—This method requires you to install the server blade in its

enclosure and assign it an IP address manually or using DHCP.

Through the server blade I/O port

In the rack—This method requires you to connect the local I/O cable to the I/O port and a client

PC. Using the static IP address listed on the I/O cable label and the initial access information on

the front of the server blade, you can access the server blade with the iLO 2 Advanced Remote

Console.

Out of the rack, with the diagnostic station—This method requires you to power the server blade

with the optional diagnostic station and connect to an external computer using the static IP

address and the local I/O cable. For cabling instructions, refer to the documentation that ships

with the diagnostic station or to the Documentation CD.

Through the server blade rear panel connectors (out of the rack, with the diagnostic station)—This

method enables you to configure a server blade out of the rack by powering the server blade

with the diagnostic station and connecting to an existing network through a hub. The IP address

is assigned by a DHCP server on a network.

The p-Class tab enables you to control specific settings for the HP BladeSystem. iLO 2 also provides web-

based status for the HP BladeSystem configuration.

Network-based PXE deployment

PXE is a component of the Intel® WfM specification. The PXE model enables server blades to load and

execute an NBP from a PXE server and to execute a pre-configured image. The image can be an OS

image created by software utilities or a boot diskette image. This feature enables a user to configure a

server blade and install an OS over a network.

Deployment overview

When a PXE-enabled client boots, it obtains an IP address from a DHCP server. The client obtains the

name of the NBP from the appropriate boot server. Then, the client uses TFTP to download the NBP from

the boot server and executes the image.
For each server blade being deployed, the PXE server must be connected to the NIC designated for PXE.

The server blade defaults PXE functions to NIC 1, but any of the two NC series NICs can be designated

for PXE in RBSU. For NIC connector locations on RJ-45 patch panels and interconnect switches, refer to

the documentation included with the server blade.

NOTE: Actual NIC numeration depends on several factors, including the OS installed on the server blade.

To deploy an OS to multiple server blades, install a PXE deployment server on a network.
