Supported IPMI Commands and B MC /PM Addresses

4.3.4.1 Request Data

4.3.4.2 Response Data

4.3.5 SetShadowRepositoryEnable

This command is used to enab le or disable the access to the shadow repository of an IPM I

controller in BMC stand-by mode.

Note: This command can only be used if IPMI controller is in BMC stand-by mode. If the IPMI

controller is not in BMC stand-by mode, “invalid command” is returned.

4.3.5.1 Request Data

4.3.5.2 Response Data

4.4 BMC and PM Addresses

To be able to send messages to other IPMI controllers (PMs) with your system management

software, you need the IPMI controller’s I2C address.

If the IPMI con troller acts as BM C, the I2C address is 2016.

If the IPMI controller is set to PM, it depends on the geographical address of the board in the

system. Refer to the system’s backplane desc ription to find the geographical addresses or use the

Force-specific IPMI command GetGeographicalAddress. The mapping of geographical and I2C
