Chapter 1 Configuring the System Console 17
Note – To view system controller boot messages, you must connect an
alphanumeric terminal to the serial management port before connecting the AC
power cords to the server.
You can log in to the system controller at any time, regardless of system power state,
as long as AC power is connected to the system and you have a way of interacting
with the system. The
sc>
prompt indicates that you are interacting with the system
controller directly. The
sc>
prompt is the first prompt you see when you log in to
the system through the serial management port or network management port.
Note – When you access the system controller for the first time and you issue an
administrative command, you must create a password for the default username,
admin,
for subsequent access. After this initial configuration, you will be prompted
to enter a user name and password every time you access the system controller.
For more information about navigating between the system console and ALOM
CMT (the system controller prompt), see the following:

ok
Prompt” on page 21

Access Through Multiple Controller Sessions
Up to nine ALOM CMT sessions can be active concurrently, one session through the
serial management port and up to eight sessions through the network management
port. Users of each of these sessions can issue commands at the
sc>
prompt. For
more information, see:
■
“Accessing the System Controller” on page 6
■
“Activating the Network Management Port” on page 7
Note –
Only one user has active control of the system console at any time. Any
additional ALOM CMT sessions afford passive views of system console activity,
until the active user of the system console logs out. However, the
console -f
command enables users to seize access to the system console from one another. For
more information, see the ALOM CMT guide for your server.
Reaching the

Prompt
There are several ways to get to the

prompt:
