Subject: temperature monitoring for UltraAX-MP
Date: Tue, 5 Feb 2002 23:36:23 +0000 (UTC)


please, help with some questions regarding temperature monitoring of
UltraAX-MP boxes..

Here is the situation:

I have old UltraAX-MP boxes running Solaris 2.6 with temperature monitoring
set up by someone 3 years ago.

The monitoring is done with a script "readi2c" that reads 1st byte of

and present it as a temperature of .. well, I don't what - probably of
CPU, motherboard, and no idea about the last two.

The driver being used thru devices is "i2cadc":

# modinfo |grep i2c
 27 646c2000   1c4a 150   1  i2cadc (I2C ADC 32-bit 1.34, 98/12/11

# ls -lL /devices/pci@1f,4000/ebus@1/i2c@14,600000/adc@0,9e:01temperature,translated
cr--r--r--   1 root     sys      150,257 Aug 17  1999 /devices/pci@1f,4000/ebus@1/i2c@14,600000/adc@0,9e:01temperature,translated

It belongs to package SUNWi2cr:
system      SUNWi2cr       Device drivers for I2C devices, (Root, 32-bit)

This package is not on standard Solaris 2.6 installation CD..

The questions are:
- what is this software istalled to monitor server temparature? Where to get it or at least the documentation?
- what do these values mean (temperature of what)?
- what is the range of normal temperature values for such server operation?

- and - what is the best way to monitor temperature of CPU, motherboard for
UltraAXMP and Ultra 420R boxes?

Thanks very much! I will appreciate any help and summarize the answers.
