CFBMC-2571：在BMC 15.12中、ONTAP集群节点意外重新启动

问题描述

• 在AFF A250、AFF C250、ASA A250、ASA C250或FAS500系统上、ONTAP集群节点在BMC 15.12中意外重新启动：
  [node_name: spmgrd: callhome.sp.hbt.stopped:alert]: Call home for SP HBT STOPPED
[node_name: env_mgr: sp.ipmi.lost.shutdown:EMERGENCY]: SP heartbeat stopped and cannot be recovered. To prevent hardware damage and data loss, the system will shut down in 10 minutes.
[node_name: env_mgr: monitor.shutdown.emergency:EMERGENCY]: Emergency shutdown: Environmental Reason Shutdown (System reboot to recover the BMC)
  
• ONTAP可能会在事件日志中报告 hwassist 错误：
  [node01: cf_hwassist: cf.hwassist.missedKeepAlive:error]: HW-assisted takeover missing keep-alive messages from HA partner (node02)
[node01: cf_hwassist: cf.hwassist.recvKeepAlive:info]: hw_assist: Received hw_assist KeepAlive alert from partner(node02)
  
• BMC系统事件日志显示BMC已执行软件重置：
  Pilot Software reset
Kernel Panic Reboot
  或
  FPGA pull BMC whole reset
Pilot FPGA AC cycle
