We have one of your servers with the following configuration:
Motherboard Model: X8DTG-DF
Back Plane: SAS818T0
IPMI FW Revision 2.0 / 01.04
OS: OpenSUSE 11.1 x86_64
We plug Nvidia GPU PCIe card into the PCIe slot. The card has ADT7473 chip which can report the temperature of the GPU chip on the card and ADT7473 has I2C interface along with the PCIe interface. We would like to know how to read the GPU temperature through your IPMI or through certain command running on your motherboard.
If the device is connected to our smbus, you can issue this master read/write to do so. Ipmitool -U ADMIN -P ADMIN -H 192.168.100.100 raw 0x6 0x52 0x5 slave_address read_byte_count register_#
For example: Ipmitool -U ADMIN -P ADMIN -H 192.168.100.100 raw 0x6 0x52 0x5 0x5e 1 0x10 to read HW monitor chip on slave address 0x5e, 1 byte date, register 0x10.
