What does ls -l /dev/ipmi0 look like? On this system,

Code: [Select]
% ls -l /dev/ipmi0
crw-rw----. 1 root ipmi 239, 0 Feb  5 09:05 /dev/ipmi0

I think you have the groups right, but either your udev rule is wrong or it hasn't taken effect yet.

Code: [Select]
$ ls -l /dev/ipmi0
crw-r-----. 1 root ipmi 241, 0  5. Feb 18:05 /dev/ipmi0

Code: [Select]
$ cat /etc/udev/rules.d/99_my.rules
# allow ipmi to be seen by ipmi group
KERNEL=="ipmi*", GROUP="ipmi", MODE="0640"

Code: [Select]
chgrp ipmi /dev/ipmi0

Code: [Select]
chmod 0640 /dev/ipmi0

What have I done wrong and how do I correct the permissions?

Oh, my bad. Yes, it does need to be writeable to send the commands to the BMC. Try 0660 instead of 0640. I wasn't thinking there.

Yes, but I don't know if that mapping applies for the T2. IPMI reports six fans on this machine. I haven't sat down to figure out which are which.

Incidentally, what is the CPU monitor tool you're using there? I like the clockspeed display.

Yes, the mapping is for the Blackbird only.
I'm using cpufreq.

It is a pity that cpufreq does not distinguish between physical cores and threads. Then it would be possible to switch off single cores and you could also switch between SMT1, 2 and 4.
