IPMItool returns false value on PowerEdge 1950

Several comments that might help.  
1. What version of OMSA do you have installed?  Depending on that you might have issues to start.  
2. If you are using OMSA 5.x then update the box to CentOS 4.4 it has newer stuff. 
3. download and build the ipmitool 1.8.7 or 1.8.8 (1.8.9 is being worked on but will take at least another week or two).
We don't have any 1950's currently but I've seen this problem when using OMSA 4.x on other servers as it installs a special dell version of the ipmi interface that conflicts with openipmi and can cause all kinds of weird stuff if you attempt to have both running at once.  You need to run one or the other at any given instant.  That is the reason to use OMSA 5.x which now uses openipmi and solves that problem.

	Dear All
	On our DELL PowerEdge 1950 (dual processors), we used
	- CentOS 4.3 (kernel 2.6.9-34.ELsmp)
	- Utility from this website: http://linux.dell.com/files/openipmi
	1. ipmitool-1.8.2-1.rhel4.i386.rpm
	2. openipmi-33.13.RHEL4-1dkms.tar.gz
	After installation, we run this command to query temperature information:
	$ ipmitool sdr
	Temp             | -46 degrees C     | ok
	Temp             | -43 degrees C     | ok
	Temp             | 40 degrees C      | ok
	Temp             | 40 degrees C      | ok
	Ambient Temp     | 30 degrees C      | ok
	CMOS Battery     | 0x00              | ok
	ROMB Battery     | 0x00              | ok
	VCORE            | 0x01              | ok
	VCORE            | 0x01              | ok
	CPU VTT          | 0x01              | ok
	1.5V PG          | 0x01              | ok
	1.8V PG          | 0x01              | ok
	3.3V PG          | 0x01              | ok
	We got 2 minus temperatures and 3 positive temperatures.
	About the minus temperatures:
	- Impossible we have minus in the temperatures even the numbers keep changing.
	About the positive temperatures:
	- The two 40 degrees C: never get change and look like these
	temperature sensors do not work
	- The 30 degrees C: sometimes change but very small from 30 to 33
	Is this a bug of opemipmi for CentOS OS ? And how to solve this ?
	Notes: Using the OpenIpmi that come with the PE 1950 CD also doesn't work.
