Currently, firmware does not support the parameters HOST_PRIV_FLASH_ACCESS and HOST_PRIV_PCC_UPDATE. Their value should stay as DEVICE_DEFAULT.
The parameter HOST_PRIV_NV_INTERNAL_CPU should either equal the parameter HOST_PRIV_NV_GLOBAL or one of them should be set to DEVICE_DEFAULT.
If the parameter HOST_PRIV_FLASH_ACCESS is not set to DEVICE_DEFAULT then the following parameters should all be set to DEVICE_DEFAULT or be equal to the value of HOST_PRIV_FLASH_ACCESS: HOST_PRIV_NV_HOST, HOST_PRIV_NV_PORT, HOST_PRIV_NV_GLOBAL, HOST_PRIV_NV_INTERNAL_CPU, HOST_PRIV_PCC_UPDATE, HOST_PRIV_FW_UPDATE.
Since the standard IPMItool commands do not cover all functionality, a set of custom NVIDIA IPMItool raw commands is available to enable configuring the NIC subsystem on the DPU directly.
IPMItool raw commands follow the following format:
ipmitool -C 17 -I lanplus -H <bmc_ip_addr> -U <username> -P <password> raw <netfunc> <cmd> <data>
Where:
netfunc – network function which identifies the functional message class, and clusters IPMI commands into sets
cmd – one byte command within a network function
data – optional element which provides additional parameters for a request or response message
The following table lists the supported IPMItool raw commands:
