The problem you are describing seems to be related to a specific hardware
problem. IOL is working perfectly on most of the hardware. IOL is definitely
a good way to access the IPMI (management).
However, I am not sure about the cluster fencing thing but more information
will be required to know if it's a good interface for that.
For your problem, I would bet in a configuration problem. You need to:
Configure IPMI IOL channel
- IP Address, Mask, gateway.
- Enable corresponding LAN (IOL) channel.
Sometimes, hardware offer BIOS menu to do the configuration.
P.S.: SOL is not what you are looking for except if you want to access to a
serial port using the LAN interfaces (Serial-Over-LAN).
To debug more your setup, we will need more meat.

Objet : [Ipmitool-devel] IPMI BMC with dedicated management port(RJ-45)....
connecting over LAN??
Greetings,
This is my first post to this mailing list and I'm hoping that someone can help
me better understand how to connect to IPMI through a dedicated management
port. I've read pretty much everything I can get my hands on and I'm still a
bit in the dark.
I have 2 servers that will eventually be members of a cluster, and my initial
plan was to use IPMI over LAN for cluster fencing. The servers have a
'management port' (RJ-45) that I connected to a switch via standard CAT-5e. I
used IPMItool to assign IP addresses/netmask, with the intention of having a
small network specifically for IPMI traffic.
The problem is that I can't connect to any remote machines using the LAN
interface. Using the -vvv option I can see the initial ping-discovery packet,
and it is being sent to the correct address, but nothing ever comes back. I can
only assume that either there is no communication, or I've setup something
wrong.
The strange thing is that the management port does not show up as an interface
when I do an ifconfig -a. However, I'm not sure if it is supposed to. This
isn't a normal NIC, it is supposed to be hooked directly into the BMC and
useable even if the server is powered down. That is why I wanted to use it for
fencing.
Has anyone seen this type of setup before? From what I've read the LAN
interface of IPMI seems to make reference to interfaces that the OS is aware
of. Is SOL what I need in order to use the management interface?
Any help would be appreciated. I can confirm that IPMI is working locally, it's
just getting to a remote machine over the network that is not working.
