系统内升级BMC固件版本
系统内升级BMC固件版本(浪潮SA5212M4)
浪潮SA5212M4的BMC固件4.31版本为当前运行最稳定的版本，适配我司的远控系统； 对java6、java7的兼容性均比较好；
1、查看bmc的固件版本

tar zxvf lxflash_v11101.tar.gz
gunzip SA5212M4_BMC_4.31.0_20190426.gz
./socflash_x64 if=SA5212M4_BMC_4.31.0_20190426该过程大约持续5~6分钟时间，刷新后丢失原BMC的配置（包含用户名密码，需要在系统中重新配置）
升级过程中BMC功能短暂不可用，不影响在线业务。
