节点报告PC电源不足严重状态
适用场景
- FAS2720
- ONTAP 9
问题描述
- 由于启动介质不可访问、节点B发生崩溃重新启动并过渡到Loader提示符。
PANIC: thread (swi4: clock (0)) on cpu 11 hung for 4001 milliseconds in process swi4: clock (0) on release 9.7P12 (C) on Fri Mar 7 11:05:17 JST 2025
- 在 节点B上更换启动介质期间、 节点A 检测到磁盘架故障、节点B处于
PC INSUFFICIENT POWER严重状态。

存储故障：
Enclosure Status: critical
Channel: 0b
Shelf: 0
Shelf Type: DS212-12
Product Serial Number: SHXXXXXXXXXXX19
Module Type: IOM12E
:
Vendor Unique Element 88-IOM12E: (PCM)
Element Status Status Bytes Status Descriptions
1: OK 01,01,00,00

- 传感器2在处理器组合件连接元件上出现错误。
环境：
Environment for channel 0a
Number of shelves monitored: 1 enabled: yes
Environmental failure on shelves on this channel? yes
Channel: 0a
Shelf: 0
SES device path: local access: 0b.00.99
Module type: IOM12E; monitoring is active
Shelf status: critical condition
SES Configuration, shelf 0:
Processor Complex attached element list: 1, 2 with error: 2
SAS Expander Module installed element list: 1, 2; with error: none
SAS Expander master module: 1
- 两个节点均处于多路径SAS连接状态、 节点B上处于严重状态的IOM12E 似乎运行正常。
- 更换 节点B 不会解决问题描述问题。
