Hardware Management Console Best Practices

- 45 -

• If you have more than one network card on your HMC, select Default if the

install images reside on the same server to which the HMC sent PXE requests.

If the install images reside on a different server, you can select another

network adapter and configure it in order to obtain the install images.

However, you must configure the second adapter using a different subnet.

• If a Restore operation is selected, the directory on the remote server must be

accessible for writing.

7.9 Automating the Process

To perform these network tasks without having to be physically at the HMC

console, you can follow the procedure below. (Note, you will still have to be

physically at the HMC console to initially set the network interface as the startup

device).

7.9.1 Server setup

There are two additional parameters that you will need to add to the append tag in

the default PXE configuration file:

append initrd=hmc/initrd.gz media=network server=192.168.1.1

dir=/home/hmc/images mode=manual mode=auto

autocfg=/home/hmc/images/HmcInstall.cfg vga=0x317

The mode parameter needs to be set to auto to indicate an unattended mode is

desired. The autocfg parameter specifies the configuration file that will specify

other information. The file must be named HmcInstall.cfg and must be in the

same directory as specified in the dir parameter.
