7.9.3 Preparing the HMC

Once the server is set up, follow the steps below to prepare the HMC. If the HMC

is currently running, then you must first shut down and restart it by using the

command hmcshutdown or by exiting the console.

When the HMC restarts, the following options will be displayed:

Press F1 for Setup

Press F12 for Startup Device

Press F1 to go to Setup. Select Startup Sequence, and change the first startup

device to be network. Save the settings and exit.

If you are not yet ready to start your network operation, you can reboot the HMC

at this point using the hard disk as the start up device. To do this, you must

override the current startup device (which is the network adapter that you have

just selected), by pressing F12 key when powering on the HMC, and select the

hard disk as current startup device. This will starts the HMC from hard disk. If

you do not see F12 in the options, the Start up Device Menu prompt is disabled in

BIOS. You will need to press F1, go into the setup menu, find and enable the Start

up Device Menu prompt under Startup menu.

When you are ready to start the network operation, you can remotely login to the

HMC via SSH and issue the command hmcshutdown –r –t now. This will restart

the HMC and use the network adapter on the HMC to send out PXE requests.

After the HMC has started up, it will recognize that an unattended operation is

desired, based on the mode and autocfg parameters in the default PXE

configuration file.

Next it will obtain the HmcInstall.cfg file from the server and use it to proceed

with the operation specified in the file. When the operation is completed, it will

complete the booting process and come up to the HMC login panel. You will have

to change the startup device list and move the network interface to the position

after the hard disk later on.

7.9.4 Setup on Server when there are multiple HMCs

In an environment with multiple HMCs, each running at different code level or

possessing different configuration, it is sometimes desirable to have a unique

configuration on the server for each HMC to send PXE requests. For example,

HMC A may choose to contact the server to do automatic backup to System X,
