更新 BMC

1. 创建一个 update_bmc.json 文件，内容如下

   {
       "Targets" :["/redfish/v1/UpdateService/FirmwareInventory/HostBMC_0"]
   }
   

2. 更新固件

   nvfwupd -t ip=<bmc-ip-address> user=<bmc-username> password=<bmc-password> update_fw \
     -p nvfw_DGX_250212.1.1.fwpkg -y -s update_bmc.json
   

   示例输出

   FW recipe: ['nvfw_DGX_250212.1.1.fwpkg']
