HP Integrated Lights-Out 2 - Manual (Page 100)

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 issues 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 appears 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 server serial port, intercepts and retransmits outgoing data to the Remote Serial
Console client, receives incoming data (from the Remote Serial Console client), and retransmits it
to the system ROM.
