Using iLO

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, refer to the Windows® Server 2003 documentation.

Security Information

If Remote Console Data Encryption is enabled, the Virtual Serial Port data stream is encrypted as data is passed between the iLO system and the viewing applet.

Virtual Serial Port and Linux

The /dev/ttyS0 device, if configured, provides the ability to obtain serial tty sessions through the iLO Virtual Serial Port Console. The Linux system must be configured correctly. Refer to your specific Linux system implementation for the appropriate commands. Some general guidelines include:

The Virtual Serial Port must be enabled through the host system RBSU. The configuration allows enabling or disabling of the Remote Virtual Serial Port. Refer to the host system RBSU documentation for the specific server for exact details. Generally, the RBSU contains a tab called BIOS Serial Console/EMS Support tab. Selecting this tab displays the EMS Console tab, which should be set to Remote. This enables both the Virtual Serial Port and the Windows® EMS Console.

To begin a shell session on the configured UART, the appropriate Linux process must be started. This process can be started from the shell, but is usually configured in the /etc/inittab file to have the process available after the kernel has booted.

Linux expects the serial port to appear at the standard UART I/O address (0x3F8); however, LOM_short_name> presents the port at the non-standard address of 0x408. To inform Linux of the non-standard address, the following command must be used. This command can be placed in the rc.serial file which is commonly called from /etc/rc.local at system startup.
