ipmitool not working on Supermicro server with Debian 12

I have a server with a Supermicro X7SBI motherboard. It has a dedicated IPMI port but I could no do anything with it, as this was a second hand server and the IPMI had a fixed IP address in the 83... range and the admin password was unknown to me. I thought that resetting it was straightforward, but ran into a few issues:

First issue: Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory

So at first, I thought that the device itself was broken. I unplugged it, checked it, but I could see the IP address and the webserver was accessible, so that seems ok. So I tried to factory reset the BIOS, still no help. Then, after some Googling, I found out that 2 fixes were needed.

1. Adapt the GRUB boot parameters for this type of board

//add logs

These articles explain what needs to be done: different ipmi_si port address and add kernel boot parameter

Run everything as root:

vi /etc/default/grub and change GRUB_CMDLINE_LINUX_DEFAULT="quiet" to

GRUB_CMDLINE_LINUX_DEFAULT="quiet ipmi_si.type=kcs ipmi_si.ports=0xca2"

Save and exit, then update your GRUB

update-grub

Reboot your sever, now the device should be found under /dev/ipmi0

Second issue: Still, there is a second problem with this version of ipmitool for Debian 12

root@debian:~# ipmitool raw 0x6 0x46 0x02
IANA PEN registry open failed: No such file or directory
61 64 6d 69 6e 00 00 00 00 00 00 00 00 00 00 00
root@debian:~# lsmod | grep ipmi
ipmi_si 73728 0
ipmi_devintf 20480 0
ipmi_msghandler 77824 2 ipmi_devintf,ipmi_si
root@debian:~# ipmitool lan set 1 ipsrc static
IANA PEN registry open failed: No such file or directory

2. Copy missing enterprise numbers

After some Googling, I found out there is some config missing for ipmitool. This command will solve that:

wget -O /usr/share/misc/enterprise-numbers.txt https://jff.email/cgit/ipmitool.git/plain/debian/enterprise-numbers.txt?h=debian/1.8.19-5


After which I could reset the ipmi ADMIN password and set the static IP address. Yeehaa!

root@debian:~# ipmitool user set name 2 ADMIN
root@debian:~# ipmitool user set password 2
Password for user 2:
Password for user 2:
Set User Password command successful (user 2)
root@debian:~# ipmitool lan set 1 ipsrc static
root@debian:~# ipmitool lan set 1 ipaddr 192.168.0.199
