Symptom
Syslog indicating power-supply failure due to either input-oring or FAN failure. These are false alarms. Following are the syslogs get generated when false alarm is hit.
ssue 1: Input Oring of A or B failure
pwr_mgmt[356]: %PLATFORM-PWR_MGMT-2-MODULE_FAILURE : Power-module 0/PM3/SP failure condition raised : Module input Or-ing A failure observed invmgr[257]: %PLATFORM-INV-6-NODE_STATE_CHANGE : Node: 0/PM3/SP, state: FAILED
OR
pwr_mgmt[356]: %PLATFORM-PWR_MGMT-2-MODULE_FAILURE : Power-module 0/PM3/SP failure condition raised : Module input Or-ing B failure observed invmgr[257]: %PLATFORM-INV-6-NODE_STATE_CHANGE : Node: 0/PM3/SP, state: FAILED
For FAN failure:
======================
pwr_mgmt[356]: %PLATFORM-PWR_MGMT-2-MODULE_FAILURE : Power-module 0/PM3/SP failure condition raised : Module fan failure observed invmgr[257]: %PLATFORM-INV-6-NODE_STATE_CHANGE : Node: 0/PM3/SP, state: FAILED
Conditions
no specific trigger. Issue is due to reading incorrect values.
Workaround
No workaround.
FAN related false alarm gets cleared within 30 seconds automatically.
Input Oring of A/B false alarm requires reseat of the power-supply. But this is very rarely seen.
