Board & CPU temperature of C8000 workstation with IPMI

[Helge Deller <deller@gmx.de>]

Hi all,

I was asked about how to remotely find out the board/CPU temperature
of a HP C8000 workstation. Here is the way I found on Debian Linux:

Instruct the kernel to load the IPMI modules:
 modprobe ipmi_si
 modprobe ipmi_devintf

You need to have the "ipmitool" installed:
 apt-get install ipmitool

Then, you can run "ipmitool sdr" to get quite some information:
root@savaria:/# ipmitool sdr

Another temperature information can be gathered from the 
built-in SATA/SCSI drives:

Install smartmontools:
 apt-get install smartmontools

Get drive information:
 smartctl --all /dev/sda | grep -i temp
Temperature Warning:  Enabled
Current Drive Temperature:     44 C
Drive Trip Temperature:        68 C


Any other ideas ?
Additionally I wonder if it's possible to get more information filled in
for IPMI on C8000 machines. E.g. is it possible on HP-UX to remotely turn
the machine on and off ?
