The iLO Virtual Serial Port is one type of iLO text-based remote console. The iLO Virtual Serial Port
gives you a bidirectional data flow with a server serial port. Using the remote console, you can
operate as if a physical serial connection exists on the remote server serial port.
The iLO Virtual Serial Port is displayed as a text-based console, but the information is rendered
through graphical video data. iLO displays this information through an SSH client when the server
is in a pre-operating-system state, enabling a nonlicensed iLO to observe and interact with the
server during POST activities.
By using the iLO Virtual Serial Port, the remote user can perform operations such as the following:
•
Interact with the server POST sequence and the operating system boot sequence.
IMPORTANT:
To start iLO RBSU during a Virtual Serial Port session, enter the key combination
ESC+8.
To start the UEFI System Utilities during a Virtual Serial Port session, enter the key combination
ESC+9.
•
Establish a login session with the operating system, interact with the operating system; and
execute and interact with applications on the operating system.
•
For an iLO running Linux in a graphical format, you can configure getty() on the server
serial port, and then use the iLO Virtual Serial Port to view a login session to the Linux operating
system. For more information, see
“Configuring the iLO Virtual Serial Port for Linux” (page 213)
•
Use the EMS Console through the iLO Virtual Serial Port. EMS is useful for debugging Windows
boot issues and kernel-level issues. For more information, see
Serial Port for the Windows EMS Console” (page 213)
