Hi all,
A recent thread inspired me to try getting a proper serial console working
on a Supermicro X9SCL motherboard with IPMI.
However I find that while I see loader messages and the getty I enabled
after boot I don't get any kernel messages which does somewhat limit the
utility..
The BMC creates COM3 (/dev/cuau2) which works with getty. I modified
/boot/loader.conf like so..
boot_multicons="yes"
boot_serial="YES"
console="comconsole vidconsole"
comconsole_speed="115200"
# Disable console flags on these 2 ports
hint.uart.0.flags="0x00"
hint.uart.1.flags="0x00"
# Set console flag
hint.uart.2.flags="0x10"
Does anyone have any hints?
Rather than using all these hints, just use these three in loader.conf:
console="comconsole vidconsole"
console_speed=115200
console_port="0x<blah>" (where <blah> is the correct I/O port for COM3, 0x3e8
maybe?)
John's suggestion works for me with a bunch of DELL's servers (1950,
2950 and R710). I can activate the SOL (Serial Over Lan) easily. I only
need to tell the loader to set the console flag for UART1 (I did it via
device.hints instead of using loader.conf, mergemaster complains every
time, I'll move that setting in the next update cycle).
I
I also needed to tell the DELL BMC (in its BIOS) to use UART1 and to
redirect the UART1 (which has no physical connector) to the UART0. I
guess you need to tweak something in the BIOS.
I'd say I know someone also doing this with an few old supermicros,
but I'm sure they run FreeBSD or Linux. I can check next monday.
OTOH, setting the comconsole speed to something higher than 9600 has
never worked for me, neither with the DELL servers nor with any other
FreeBSD box without SOL. The handbook states that the "comconsole_speed"
sets the console speed, but John says "console_speed" is the parameter.
Is the handbook outdated?
