Sorry chaps, for some reason I didn't get a prompt that you had posted.
I'm no longer getting emails about posts either. That functionality seems to have died.

Thanks also Stux, I lowered FAN1 thresholds and this is the result:
Code:
root@NAS:/mnt/Storage/Scripts # ipmitool sensor thresh FAN1 lower 0 100 200
Locating sensor record 'FAN1'...
Setting sensor "FAN1" Lower Non-Recoverable threshold to 0.000
Setting sensor "FAN1" Lower Critical threshold to 100.000
Setting sensor "FAN1" Lower Non-Critical threshold to 200.000
root@NAS:/mnt/Storage/Scripts # ipmitool sensor

I lost a drive this week: that's the second Seagate Ironwolf. May then October. I am waiting for the RMA.
Thanks
I'm completely stumped. The portion of the code that controls the CPU fan, checks its speed, and resets the BMC, etc is unchanged from Stux's original code. I cannot find anything in the code that could explain the behavior you are getting.

So, I wonder if there is some chance of a hardware issue or error.
  1. Please confirm that the Intel CPU fan you are using is a four wire PWM fan. The script only works with PWM fans.
  2. Check the fan wiring again, and confirm that the CPU fan really is hooked up to the FAN 1 header.
  3. Carefully check the fan connector, and ensure that it is fully engaged on the pins on the FAN 1 header.

I'm no longer getting emails about posts either. That functionality seems to have died.

I checked again.
The cpu fan has 4 wires, as does the header for FAN1.
I unplugged and plugged it back in before running the script again: still mis-reads the speed.

A few weeks ago I even tried connecting the cpu fan to the FAN2 header with a view to try and eliminate at least some potential hardware issues.
That could leave:
both headers damaged
the motherboard defective
the cpu fan or lead defective
anything else?

This is an X11SSM-F-O board. Forgive my ignorance, but is this board set up different from X9 and X10 boards?

It is quite possible that the IPMI commands are different for X11 boards. Lets try the following after logging into the server via ssh:

ipmitool raw 0x30 0x45 0x01 0x01 #This sets the BMC mode to Full Speed.

ipmitool raw 0x30 0x70 0x66 0x00 0x00 #This checks the duty cycle in Zone 0. The result is hex, with 64 being 100% duty cycle. 32 is 50% duty cycle.

ipmitool raw 0x30 0x70 0x66 0x00 0x01 #This checks the duty cycle in Zone 1. The result is hex, with 64 being 100% duty cycle. 32 is 50% duty cycle.

ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x32 #Sets duty cycle in Zone 0 to 50% (i.e. 32/64)

ipmitool raw 0x30 0x70 0x66 0x00 0x00 #This checks the duty cycle in Zone 0. The result is hex, with 64 being 100% duty cycle. 32 is 50% duty cycle.

ipmitool raw 0x30 0x70 0x66 0x01 0x01 0x32 #Sets duty cycle in Zone 1 to 50% (i.e. 32/64)

ipmitool raw 0x30 0x70 0x66 0x00 0x01 #This checks the duty cycle in Zone 1. The result is hex, with 64 being 100% duty cycle. 32 is 50% duty cycle.

ipmitool raw 0x30 0x45 0x01 0x01 #This sets the BMC mode back to Full Speed.

Let us know the results. This should help determine whether your board has the same command set.

This suggests that there is some relevant difference between the X11SSM and the X10 boards that this script was written for. Ask SuperMicro what the commands are to set and check duty cycle on your board. If you can find the correct commands, we can modify the script to use them.

So, still reading 100% when set to 50%.

Yup, that’d be the problem right there :(

Could be the max mode ensures 100% now. What fan modes are available in your ipmi?

The X11SSM-F has the same BMC as my X10SRH-cF board, so I'd hope it had the same command set. One possible explanation for the observed behaviour:

The case fans (Fractal Design Silent Series) are not PWM fans, so they would stay at full speed. Maybe the X11SSM-F board has different fan zone allocation than the X10SRH. I.e., maybe FAN 1, 2, etc are in Zone 1, not Zone 0.

Try the following commands, and report the results:

ipmitool raw 0x30 0x45 0x01 0x01 #This sets the BMC mode to Full Speed.

ipmitool sdr | grep FAN #reports all fan speeds

ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x32 #Sets duty cycle in Zone 0 to 50% (i.e. 32/64)

ipmitool sdr | grep FAN #reports all fan speeds

ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x32 #Sets duty cycle in Zone 0 to 50% (i.e. 32/64)

ipmitool sdr | grep FAN #reports all fan speeds

ipmitool raw 0x30 0x70 0x66 0x00 0x00 #This checks the duty cycle in Zone 0. The result is hex, with 64 being 100% duty cycle. 32 is 50% duty cycle.

ipmitool raw 0x30 0x70 0x66 0x00 0x01 #This checks the duty cycle in Zone 1. The result is hex, with 64 being 100% duty cycle. 32 is 50% duty cycle.

ipmitool raw 0x30 0x45 0x01 0x01 #This sets the BMC mode back to Full Speed.

SM replied :
It is not supported to check and set the duty cycle via RAW command, we only support the presets that already exist for fan speed.

Well. That sucks.

Mind you. Checking the duty cycle does seem to work. If it were my system, I’d try a few different mode and see if there are any changes. Maybe full mode is locked to 100%.

My case is a Fractal Design 804. The hard drives are all together on one side of the case above the psu. 3 Fractal Design Silent R2 fans on that side are connected to a fan hub
https://www.amazon.co.uk/Phanteks-PH-PWHUB_01-ph-pwhub-01-PC-Casing/dp/B00M0R05WE
The hub is connected to header FAN A on the mb.
Although not strictly pwm I believe this arrangement does provide speed control of fans in response to temperature.

I thought this was the best arrangement for this case. The alternative would have been the hub provided by Fractal which gives manual control at a fixed speed. No response to temperature

I've got a Fractal Design 804 as the case on my backup server.

The point of my message was I was wondering if perhaps the fan zones were designated differently on the X11SSM, which could explain the observed behavior, and allow us to solve the problem. The suggested commands would provide information to confirm or deny this hypothesis.

My IPMI gui has 4 fan modes:


After the commands to set duty cycle to 50% the fan speed dropped for a moment then resumed at Full.

Should one of the commands above have been for Zone 0 and the other for Zone 1?

That’s good news in a way, at least it dropped.

Helps confirm a possible theory I had that the max mode was now enforcing 100%. Previously max mode only sets the fans to 100% when changed to, then it doesn’t adjust them. Other modes adjust the fans more often.

You may want to try different modes and see if you have different results with the pwm raw commands.

By running a few commands I have found I can run RAW commands to change fan mode, which work. However, if in Full mode the fans continue regardless at max speed.

To get out of that, I have to use IPMI gui to select a different mode, eg Optimal/Save/Reset BMC

If I start in Optimal say, RAW commands can change the duty cycle, eg to 50% and this works for both Zones 0 and 1 see below:

Code:
root@NAS:/mnt/Storage/Scripts # ipmitool raw 0x30 0x70 0x66 0x00 0x00

root@NAS:/mnt/Storage/Scripts # ipmitool raw 0x30 0x70 0x66 0x00 0x01
 64
root@NAS:/mnt/Storage/Scripts # ipmitool raw 0x30 0x45 0x01 0x01

root@NAS:/mnt/Storage/Scripts # ipmitool raw 0x30 0x45 0x00
 01
root@NAS:/mnt/Storage/Scripts # ipmitool raw 0x30 0x45 0x01 0x02

root@NAS:/mnt/Storage/Scripts # ipmitool raw 0x30 0x45 0x00
 02
root@NAS:/mnt/Storage/Scripts # ipmitool raw 0x30 0x45 0x01 0x00

 04
root@NAS:/mnt/Storage/Scripts # ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x32

root@NAS:/mnt/Storage/Scripts # ipmitool sdr | grep FAN
FAN1			 | 1900 RPM		  | ok

Be careful, you might want to verify that the speeds don’t reset st periodic intervals.

I think my script (and derivatives) can be easily modified to use optimal instead of max, and they might even gracefully deal with the periodic speed changes as part of their low/max detection and n stage checks.

I'm pretty sure that the BMC will attempt to keep controlling the fan speed in response to CPU and a temp sensor on the mother board, if the mode is Optimal. It is quite probable that the BMC will also attempt to control the fans in other fan modes too. You'll need to do some testing to see.

My notes say that the raw command to set Optimal mode is ipmitool raw 0x30 0x45 0x01 0x02 and the command for Standard mode is ipmitool raw 0x30 0x45 0x01 0x00.

I'm not sure what the command for Heavy I/O mode is. It might be ipmitool raw 0x30 0x45 0x01 0x03 or ipmitool raw 0x30 0x45 0x01 0x04

The info on this page at ServeTheHome suggests that the BMC sets the peripheral fan speed to a fixed value in Optimal and Heavy I/O settings. Thus it is possible that this might allow the script to work.

The same page says that the BMC will attempt to control the CPU fan in all modes except Full. So, you would need to select the option in the script to have the script not control the CPU fan. Just leave that to the BMC (and test it to make sure it keeps the CPU temperature at a suitable value when it is under load).
