Using iLO 2 104
Using the iLO 2 remote serial console, the remote user is able to perform operations such as interacting
with the server POST sequence and operating system boot sequence; establishing a login session with the
operating system, interacting with the operating system; and executing and interacting with applications
on the server operating system. Users of the Microsoft® Windows Server™ 2003 operating system have
the ability to execute the EMS subsystem through the remote serial console. EMS is useful for debugging
operating system boot and problems at the operating system kernel level.
Remote Serial Console
The Remote Serial Console enables you to access a VT320 serial console from a Java™ applet-based
console connected to the iLO 2 Virtual Serial Port through a browser. Launching the Remote Serial
Console enables you to exchange text data with the host. The Remote Serial Console option is compatible
with both Windows® and Linux host operating systems and requires JVM.
The flow of data is a bi-directional stream sent to the server serial port. Three types of data can appear on
a HP ProLiant server serial port:
•
Windows® EMS console
•
Linux user session through serial tty (ttyS0)
•
System POST dialog (if BIOS serial console redirection is enabled)
The current configuration is displayed on the Remote Console Information page when you click the
Remote Console tab. You can alter the current settings using the host system RBSU, accessed during a
server reset.
Configuring Remote Serial Console
To successfully use the Remote Serial Console, the server software and firmware must be configured
correctly. To configure the server POST firmware, the server System RBSU must be invoked to set the serial
port parameters. You must configure the RBSU to enable BIOS Serial Console Redirection mode. This
mode instructs the server system ROM to send data to, and receive data from, the server serial port.
When the iLO 2 firmware enters Remote Serial Console mode, iLO 2 enables a serial port in place of the
