I've noticed the same thing on RHE 5.4 since a recent OpenIPMI update:

 

OpenIPMI.x86_64                      2.0.16-5.el5_4.1       installed

 

Looks like the 2.0.16-5 update broke things...  pretty much everything
around and after the ECC checks starts to return "Not Readable".

Subject: IPMI not showing all the sensor readings

 

Hello,

I have PowerEdge 610 with Intel Xeon 5520 Processor and CentOS 5.3
installed on it. 
I installed OpenIPMI-tools-2.0.16-5.el5.x86_64 and using ipmitool to
monitor the power usage, voltage, temperature of various components by
executing  "ipmitool  sdr" command.

It lists a bunch of sensors which have their readings as "Not Readable".
E.g. 
CPU Temp Interf  | Not Readable      | ns

1. Can someone please let me know how can I retrieve the value of this. 
2. SDR gives a long list of sensors and many are named as Temp. I do not

understand which component's temperature is it displaying.
Is there a manual which explains what each of the sensors signify.
3. Is there a special sensor for reporting Power and temperature of each
CPU?
If yes, which one?
4. What is the resolution and accuracy of these sensors? This is
important to me, as
I am doing some experiments on these machines and need to report various
IPMI
attributes.
