PER200 Ipmi

Hi all,

I'm working on a PowerEdge R200. Using the following tutorial:

http://www.dell.com/downloads/global/power/ps4q04-20040204-Murphy.pdf

I have tried to read sensor info from the BMC of my R200 so I typed the command:

./ipmitool -I lan -H 192.168.33.181 -U root -a sensor list

//the output is:

Error reading sensor PCI System Err (#05)

Question 1) :
the sensor Temp and Interface Temp have the state 'na' (which means 'not available' state, I think); so is there  a way to read the their value???

Question 2) :
I've installed a Linux release (Linux 2.6.27-gentoo-r2) then I've built a kernel with IPMI support and I've used OpenIpmi to develop a small program to read the ipmi info by my self. When I retrieved the value of Temp and Temp Interface sensors, I've read a negative number.
My question is: in this case I have two IPMI (Ipmi 1.0 Dell Native and Ipmi loaded into kernel) which try to speak with the same BMC, isn't true? If it is true, can they coexist?

Question 3) :
The R200 wich I'm working on, has the BMC 1.79 and BIOS Revision 1.2.1 .... if I make some upgrade can I have any better results? can I read Temp and Interface Temp?


Thanks in advance for your response.
