多风扇故障警报、系统在更换PSU模块后发出噪音
适用场景
- AFF 和 FAS 系统
- ONTAP 9
- 磁盘架
问题描述
- 两个节点都会在事件日志中频繁报告以下警报：
[Node-01: statd: monitor.shelf.fault:debug]: Critical fault reported on disk storage shelf attached to channel 0a. Check fans, power supplies, disks, and temperature sensors.
[Node-01: statd: monitor.fan.failed:debug]: Multiple fans has failed.
[Node-01: env_mgr: monitor.fan.warning:debug]: multiple fans have failed. Replace it to avoid overheating
[Node-01: env_mgr: callhome.c.fan.fru.fault:debug]: Call home for CHASSIS FAN FRU FAILED: Multiple fans have failed
- 的输出
storage show fault显示未检测到某个电源：
::> system node run -node * -command storage show fault

Channel: 0a
Shelf: 0
Shelf Type: DS224-12

- 即使在更换PSU后、SP传感器也无法报告读数：

PSU_FAN FAIL_2
- 由于未检测到一个PSU风扇、另一个PSU风扇开始更快地旋转、发出噪音。
- SP/BMC已在最新固件版本上。
- 重新启动SP/BMC不会停止警报。
- e0M端口不会受到高流量的影响、如知识库文章所述 ：Chassis fan fru failed：Multiple fans have failed Even after ime就是 在升级SP/BMC之后
- 尽管 逐个执行节点的接管/恢复、问题描述仍会继续存在。
