[lm-sensors] Do my Xeon's have a temp sensor in them?

[Rick Flower]

Hi all.. I'm a lm-sensors newbie.. I've got an older Compaq Proliant 
5500 rackmount server I recently acquired and I've got it running Linux 
2.6.9 currently.. Its configured with 4 Pentium III Xeons -- 500Mhz, 1Mb 
Cache, etc (see output below from /proc/cpuinfo).  Anyway, in reading 
the various documents on the website, it sounded like I might have one 
sensor for each Xeon cpu in the machine (and perhaps I'd only be able to 
read one of them) -- however, I can't get lm-sensors to find any chips 
for it..   So, am I incorrect in this assumption that these Xeons have 
sensors build on them or is it just a configuration issue?  I've also 
included the output from the sensors-detect program below.. Any 
comments/suggestions would be greatly appreciated!

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

It is generally safe and recommended to accept the default answers to all
questions, unless you know what you're doing.

 We can start with probing for (PCI) I2C or SMBus adapters.
 You do not need any special privileges for this.
 Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-piix4' for device 00:0f.3: Intel 82371AB PIIX4 ACPI
Probe succesfully concluded.

We will now try to load each adapter module in turn.
Module `i2c-piix4' already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

 To continue, we need module `i2c-dev' to be loaded.
 If it is built-in into your kernel, you can safely skip this.
i2c-dev is already loaded.

 We are now going to do the adapter probings. Some adapters may hang halfway
 through; we can't really help that. Also, some chips will be double 
detected;
 we choose the one with the highest confidence value in that case.
 If you found that the adapter hung after probing a certain address, you can
 specify that address to remain unprobed. That often
 includes address 0x69 (clock chip).

Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan the ISA bus? (YES/no):

  Trying address 0x0290... Failed!
Probing for `National Semiconductor LM78-J'
  Trying address 0x0290... Failed!

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan for Super I/O sensors? (YES/no):
Probing for `ITE 8702F Super IO Sensors'
  Failed! (skipping family)
Probing for `Nat. Semi. PC87351 Super IO Fan Sensors'
  Failed! (skipping family)

  Failed! (skipping family)
Probing for `VT1211 Super IO Sensors'
  Failed! (skipping family)
Probing for `Winbond W83627EHF Super IO Sensors'

Do you want to scan for secondary Super I/O sensors? (YES/no):

  Failed! (skipping family)

 Sorry, no chips were detected.
 Either your sensors are not supported, or they are
 connected to an I2C bus adapter that we do not support.
 See doc/FAQ, doc/lm_sensors-FAQ.html, or
 http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/lm_sensors-FAQ.html
 (FAQ #4.24.3) for further information.
 If you find out what chips are on your board, see
 http://secure.netroedge.com/~lm78/newdrivers.html for driver status.

[lm-sensors] Do my Xeon's have a temp sensor in them?

[Rudolf Marek]

hello,

It might happen that the sensor is on another bus, or uses some other chips.
But I think compaq has its own proprietary infrastructure called cpqhealth but I think it is not for 2.6 kernels.
Please ask them for support, or how to access their chips.

You can also try:

modprobe i2c-piix4
modprobe i2c-dev
i2cdetect 0

And send the output to us. It will detect again in "raw" form. But I think there will be nothing.

Regards

Rudolf

Rudolf,

Thanks for the reply & suggestions.. I looked into the cpqhealth module 
and beleive it's way too new for my machine.. My machine is circa '99 or 
somewhere around there and so it's not something I can use.  I'll keep 
dicking around with things -- I'm currently playing with the ACPI stuff 
since it appears to show up disabled and am not sure if that has anything 
to do with this issue or not.  Perhaps my machine is just too old for some 
of this fancy shmancy stuff..
