Configuration for Windows Server 2003 and 2008 operating systems
The Windows EMS Console is available in the Windows Server 2003 and 2008 operating systems. You
must configure the EMS console within the operating system before you can use VSP. Refer to your
operating system documentation for information about how to enable the EMS console. iLO displays an
error message when you open VSP through the Internet browser, if you have not enabled the EMS
console.
Configuration for Linux operating systems
You can manage Linux servers remotely using console redirection. To configure Linux to use console
redirection, you must implement the following changes in the Linux boot loader (GRUB):
• Turn off the splash image.
• Configure the GRUB to redirect messages to the serial port to display messages while Linux starts.
• Configure the GRUB to enable the Linux kernel to redirect messages to the serial port to display Linux
console messages.
Sample GRUB configuration file for Red Hat Linux:
default=0
timeout=10
splashimage=(hd0,2)/grub/splash.xpm.gz
title Red Hat Enterprise Linux Server(2.6.18-164.e15)
root (hd0,2)
kernel /vmlinuz-2.6.18-164.e15 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.18-164.e15.img
Turn off the splash image
Since the VSP is non-graphical, you must turn off the splash image. To do that, comment out that line by
inserting the pound (#) character at the beginning of the line, as follows:
default=0
timeout=10
#splashimage=(hd0,2)/grub/splash.xpm.gz
title Red Hat Linux (2.6.18-164.e15)
root (hd0,2)
kernel /vmlinuz-2.6.18-164.e15 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6,18-164,e15.img
Configure the GRUB to redirect messages to the serial port
Define the serial interface (ttyS0) as the default interface so that if no input arrives from the local keyboard
within 10 seconds (the default timeout value), the system will redirect output to the serial interface (VSP).
You must insert the serial command as shown below to define the serial interface as the default interface:
serial -unit=0 -speed=115200
terminal -timeout=10 serial console
default=0
timeout=10
#splashimage=(hd0,2)/grub/splash.xpm.gz
title Red Hat Linux (2. 6.18-164.e15)
root (hd0,2)
