Currently, firmware does not support the parameters
HOST_PRIV_FLASH_ACCESSandHOST_PRIV_PCC_UPDATE. Their value should stay asDEVICE_DEFAULT.The parameter
HOST_PRIV_NV_INTERNAL_CPUshould either equal the parameterHOST_PRIV_NV_GLOBALor one of them should be set toDEVICE_DEFAULT.If the parameter
HOST_PRIV_FLASH_ACCESSis not set toDEVICE_DEFAULTthen the following parameters should all be set toDEVICE_DEFAULTor be equal to the value ofHOST_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 BlueField 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 setscmd– one byte command within a network functiondata– optional element which provides additional parameters for a request or response message
The following table lists the supported IPMItool raw commands:
