CODE EXAMPLE 6-2OpenBoot Diagnostics Error Message

The i2c@1,2e and i2c@1,30 OpenBoot Diagnostics tests examine and report on environmental monitoring and control devices connected to the Sun Fire V490 server’s Inter-IC (I2C) bus.

Error and status messages from the i2c@1,2e and i2c@1,30 OpenBoot Diagnostics tests include the hardware addresses of I2C bus devices:

Testing /pci@9,700000/ebus@1/i2c@1,2e/fru@2,a8

The I2C device address is given at the very end of the hardware path. In this example, the address is 2,a8, which indicates a device located at hexadecimal address A8 on segment 2 of the I2C bus.

To decode this device address, see “Reference for Decoding I2C Diagnostic Test Messages” on page 111. Using TABLE 6-12, you can see that fru@2,a8 corresponds to an I2C device on DIMM 4 on processor 2. If the i2c@1,2e test were to report an error against fru@2,a8, you would need to replace this memory module.
