问题描述

  • 在某些存储系统上、非易失性内存(NVMEM)电池的学习周期功能会在活动学习周期内中断电池传感器的某些读数。
  • 低于阈值的传感器读数可能会触发误报警报、并且 发生原因 ONTAP可能会关闭。

  • 以下型号可能会受到影响:
  • AFF A800、AFF A700、AFF A320、AFF A220、AFF A200、AFF C190
  • FAS9000、FAS8200、FAS2750、FAS2720、FAS2650、FAS2620

  • 发生此问题描述时、您可能会看到以下错误消息:
    01:03:53 [node01:nvmem.battery.fccLowCrit:EMERGENCY]: The NVMEM battery full-charge capacity is critically low (15 cycles). To prevent data loss, the system will shut down in 20 minutes.
    01:04:34 [node02:nvmem.battery.capLowCrit:EMERGENCY]: The NVMEM battery capacity is critically low (0 cycles). To prevent data loss, the system will shut down in 20 minutes.
    01:04:53 [node01:callhome.battery.failure:EMERGENCY]: Call home for BATTERY (full charge capacity low) CRITICAL.
    01:05:03 [node01:callhome.battery.failure:EMERGENCY]: Call home for BATTERY (capacity low) CRITICAL.
    01:23:54 [node01:monitor.shutdown.emergency:EMERGENCY]: Emergency shutdown: Environmental Reason Shutdown (Battery PCT capacity critical)
    01:33:39 [node1:nvmem.battery.capNormal:notice]: The NVMEM battery capacity is normal.

  • 误报警报消息后有时会出现"恢复正常"消息。电池学习周期每70天进行一次、大约需要19小时才能完成。在此期间、系统容易受到此问题描述的影响。
