Configuring The Serial Port Redirection - Inspur OS Installation Manual

If you have configured multiple coredump files, only one of them can be activated.

Configuring the Serial Port Redirection

Critical errors, such as system crashes, may occur during server testing and daily
use. When such errors occur, the OS will export some important information to a
serial port. It is very inconvenient to obtain the information through a connection to
the physical serial port. Therefore, you are advised to configure the serial port
redirection so as to obtain the information via
The serial port redirection configuration for Linux is described below.
Generally, a server does not provide a physical serial port. Hence, you need to
configure SOL serial port redirection. SOL is the acronym for Serial Over LAN, which
is a feature of IPMI v2.0. With the mechanism provided by SOL, the serial port
controller of the remote management system can be redirected to the local site
through the IPMI session based on IP network. SOL enables administrators to
access the IP-based remote system serial port. As long as no network failure occurs
in the server room, the administrators can access the serial port output of the
failed server through any server that supports SOL.
A remote management application can establish an IPMI over LAN session with
BMC. After the session is established, the remote console can activate SOL. Then
any characters sent from the target motherboard will pass through the BMC and be
packaged by the BMC and sent to the remote console via LAN. Correspondingly,
the package sent from the LAN will be unpacked by the BMC and sent to the serial
port controller of the motherboard in a correct way. For standard serial port
controllers, BMC needs to obtain the baud rate of the serial port controller on the
motherboard, so as to keep its own controller in sync. Hence, when using SOL, you
need to set the baud rate of the serial port controller of the BMC to be the same as
that of the motherboard.
For a server, on which SOL is enabled and the port and baud rate in the BIOS and
OS are configured the same as those of the BMC, you can connect it to the serial
SOL BMC
