Using the Harddrive Spin Up Delay option allows you to change the spin up delay time
for SCSI hard disk drives attached to your system. Spin up delay values can be entered
manually, or you can use a default setting (two seconds). All values are measured in
seconds.
Attention: Setting the value lower than the default can prevent successful booting
because the system power handling capabilities might be exceeded. If the system no
longer boots after setting this value, access this utility again and increase the value. It is
also possible that adding disk drives can cause similar symptoms. Changing this value
changes the surge current requirements on the system. As you increase the value, the
surge current requirements on the system are decreased.
Select Console
Select this option to define which display is used by the system for system
management. If no console is selected, the console defaults to serial port 1.
Selecting this option causes a screen similar to the one that follows to display on each
console that can be used as a firmware console. Follow the instructions on the screen
to select a particular console.
Note: The firmware console is independent from the AIX console.
