Windows EMS Console
The Windows EMS Console, if enabled, provides the ability to perform Emergency Management
Services in cases where video, device drivers, or other operating system features have prevented
normal operation and normal corrective actions from being performed.
iLO 2, however, enables you to use EMS over the network through a Web browser. Microsoft EMS
enables you to display running processes, change the priority of processes, and halt processes.
The EMS console and the iLO 2 Remote Console can be used at the same time.
The Windows EMS serial port must be enabled through the host system RBSU. The configuration
allows for the enabling or disabling of the EMS port, and the selection of the COM port. The iLO
2 system automatically detects whether the EMS port is enabled or disabled, and the selection of
the COM port.
To obtain the SAC> prompt, entering Enter might be required after connecting through the Virtual
Serial Port console.
For more information on using the EMS features, see the Windows Server 2003 documentation.
Virtual serial port raw mode
You can use the virtual serial port capability of iLO 2 to connect a Windows Kernel Debugger
from a remote client using WiLODbg.exe. WiLODbg.exe bypasses the decoding of bytes by the
iLO 2 firmware. After bypassing the decoding of bytes, the virtual serial port is in RAW mode
(unprocessed) and sent directly to the serial port.
The WiLODbg.exe utility is executed on a client system with the Microsoft application WinDBG.exe
or KD.exe installed. When you execute WiLODbg.exe, it establishes a virtual serial port connection
to iLO 2 and enables RAW mode. WiLODbg.exe also automatically launches WinDBG.exe with
the appropriate switches necessary for WinDBG.exe to connect to the remote iLO 2 device.
To configure the server, you must configure the System RBSU:
1. To enable a virtual serial port, assign Virtual Serial Port a COM port from the System Options
menu.
2. Set BIOS Serial Console Port and EMS Console to Disable, or set it to the same port as an
embedded serial port.
3. Set the Microsoft Windows debug port to the same port as the virtual serial port. You can use
the bootcfg command or modify the boot.ini file.
Example using the bootcfg command:
At the command prompt on a Windows server, issue the following command:
Bootcfg /debug on /port com2 /baud 115200 /id 1
Example of a modified boot.ini file:
[boot loader]
timeout=5
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows
Debug (com2)" /fastdetect /debug /debugport=com2 /baudrate=115200
If the server is configured to boot into debug mode, and a normal virtual serial port connection
is established while the server is booting, several bytes of debug data are sent to the virtual
serial port client. To avoid this, do not boot the server into debug mode while a normal virtual
serial port connection is in use.
