how to know fan speed using i2c commands on IA64


I am trying to find fan speed on IA64.

In x86 or x64,I can easily get it by using ipmitool which shows fan speed.But in IA64 platforms, the ipmitool doesnt show any such information.Rather I guess I need to use i2c commands as the fans are connected on the i2c bus.But I dont know any interface which supports i2c commands,basically I dont have any knowledge on how to use i2c commands.

Any help regarding this would be helpful.Can any one provide me with some useful docs n links?

OS: SLES 10 IA64

Target Platform: HP rx2660 server IA64

fancontrol ... works with lmsensors ...may work with your board.

Also check with ipmi support in phoronix test suite for ia64.

It is very efficient on non ia64
