We have a number of Dell PowerEdge 2950's that we boot using the built
in SOL, which does run over IP as we use it across a routed VPN
backbone (server in the data center, console in the office). We have
found that the IPMI serial port is connected to the system as COM2,
which we select in the bios configuration. We then set device.hints
so that the freebsd console is set to use the same port. We use the
open source ipmitool to access the ipmi controller, and serial port,
on the system.
Aha! This is something already.
When our system boot it says:
Mar 5 23:59:04 aaa kernel: sio0: configured irq 4 not in bitmap of
probed irqs 0
Mar 5 23:59:04 aaa kernel: sio0: port may not be enabled
Mar 5 23:59:04 aaa kernel: sio0: <16550A-compatible COM port> port
0x3f8-0x3ff irq 4 flags 0x10 on acpi0
Mar 5 23:59:04 aaa kernel: sio0: type 16550A
Mar 5 23:59:04 aaa kernel: sio1: configured irq 3 not in bitmap of
probed irqs 0
Mar 5 23:59:04 aaa kernel: sio1: port may not be enabled
My guess is that sio0 is the real port and sio1 is the IPMI port of
Intel AMT. But what does this message
really say? What must i do to enable the port?
The other question, do i need to include
device ipmi
in the kernel config? And how do i tell the boot loader to redirect its
output to serial port? Sorry,
working with freebsd for 10 years now but never touched this issue.
This is the dmesg from our servers (sio1 is the ipmi SOL port):
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 on acpi0
sio0: type 16550A
sio1: <16550A-compatible COM port> port 0x2f8-0x2ff irq 3 flags 0x10 on
acpi0
sio1: type 16550A, console
As far as I know it is not required to have ipmi in the kernel (we dont
have it in our kernels) to use the SOL port.
This page should help you setup the serial console:
