If no bootable operating system image is found on any of the storage devices listed
in the system firmware boot list, then the server attempts to boot again. With each
attempt, you have the opportunity to start the System Management Services (SMS)
as described in Chapter 3, “Using System Management Services.”
Stopping the Server
Attention: When you use the shutdown procedure for your server, enter the correct
shutdown command for your operating system before you stop the server. Failure to
do so may result in the loss of data. If you need information on the shutdown
procedure for your operating system, see the operating system documentation.
1. Before stopping the programs and operating system, notify your system
administrator and users that the server is going to be shut down.
2. After you shut down the operating system, turn off the server.
3. Set the power switches of the attached devices to Off.
Using the Power Switch and Indicator
The power switch and indicators on the front of your server allow you to control
power to the server, observe server power status, and observe disk activity.
These features also have other built-in capabilities to assist you in diagnosing system
problems and observing server status:
When the server is turned on by pressing the power switch, the power LED lights
steadily.
The disk drive LED lights whenever the hard disk drives within the server are
being used.
If AIX is installed and running, a memory dump of system information can be
requested.
To enable this function, the sysdumpdev -K command must be executed
before an error condition exists.
To request the memory dump, press the reset button on the operator panel.
Requesting a memory dump directs AIX to save system information to a
predefined file before turning off the system. This feature can be used to
assist in recovery from system problems.
When a memory dump has been requested, the power LED blinks quickly
(about 10 flashes per second) to indicate that the dump has been started.
This blinking ceases after about a minute whether or not the dump is
