Hardware Management Console Best Practices

3 Initial Configuration

HMCs come with Licensed Machine Code preinstalled, but you may need to

reinstall if the code has been superseded or you have a disk failure. Customized

setup and installation instructions come with all new machines or upgrades. Prior

to receiving a new system, users can refer to the IBM Systems Hardware

Information Center online to see what specific preparations may be needed.

3.1 Install and Configure the HMC First

If you are going to use a private network, you should install and configure your

HMC before connecting it to a network or powering on the servers it will manage.

This will enable you to configure the networks properly and bring up DHCP in an

orderly manner and insure that the managed servers will connect correctly. The

HMC should be located within 50 feet of the servers it manages and with easy

access to networks and power. If a dial-up modem is going to be used to contact

IBM Service, a telephone line also needs to be available.

The POWER5 HMC includes a Setup Wizard that can be used by a systems

administrator to customize the system. The wizard starts the first time you login

after a new installation. You are not required to use it. Administrators who are

comfortable with the HMC Configuration menus are free to use them instead. The

Setup Wizard can be run at any time from the main menu on the HMC console.

3.2 Changing Passwords

Whether you use the Setup Wizard or the HMC Configuration menus, the first

task you should do is change the hscroot and root passwords from their default

values. As shipped with the Licensed Machine Code, the hscroot password is

“abc123.” It should be changed to a new, seven-character value. The default

root password is “passw0rd,” and it needs to be changed as well. Logging in as

root is disabled. Note that while you will not be using the root password for daily

administration, you may need it from time to time when performing problem

determination, usually with the assistance of IBM support or product engineering.

Be sure to save all passwords in a secure location where they can be retrieved in

an emergency.
