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。

• 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。
