Node reports PC INSUFFICIENT POWER Critical status
Applies to
- FAS2720
- ONTAP 9
Issue
- Node B experiences a PANIC REBOOT and transitions to the Loader prompt due to inaccessible boot media.
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
- During the boot media replacement on Node B, Node A detects a shelf fault and node B is
PC INSUFFICIENT POWERcritical status.

- Sensor 2 has an error on the Processor Complex attached element.
ENVIRONMENT:
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
- Both nodes are in a multipath SAS connection state, and the IOM12E in critical status on Node B appears to be functioning normally.
- Replacing Node B does not resolve the issue.
