Console Output Overview - Sun Microsystems Fire X4150 Installation Manual

You can use the remote KVMS Over IP feature of the ILOM or ELOM to do the
■
same thing from a remote system.
You can view the messages on a serial port, either through the service processor
■
(SP) secure shell (SSH), or by connecting directly to the server's serial port.
■
■
Note – You can also connect to the SP directly through the SP serial port, which is
different from the host serial port. See your SP documentation to use this option.

Console Output Overview

Video Port
During an OS installation all console output goes to the video port until the
operating system assumes control of the display. When and how this happens
differs, depending on which operating system is being installed, but they all have
two things in common:
They don't do this until the install is advanced enough that you don't need the
■
console output.
They have a method of displaying console output once the OS is installed.
■
Serial Port
Any time you boot or restart the system, all output is also displayed on the serial
port, up to and including POST test results, and a message that prompts you to enter
the BIOS.
Whether or not any more output goes to the serial port depends on the remote
access/external port setting in the BIOS. See
Output to the Serial Port" on page
4 Sun Fire X4150, X4250, and X4450 Servers Operating System Installation Guide • November 2009
If you use the direct connection to the serial port, you must configure the BIOS
to direct output to the serial port.
If you use the SP SSH option, you must configure the BIOS to direct output to
the serial port, and you must configure the SP to connect to the console.
