Opened: Apr 26, 2016 Severity: 3-Major
After removing the second power supply (PS2), running system_check indicates that the power supply status is still good: system_check -d | grep power Chassis power supply 1: status FAN=good; VINPUT=good; VOUTPUT=good; STATUS=good Chassis power supply 2: status VINPUT=good; VOUTPUT=good; STATUS=not present
Erroneous indication that the power supply is still good
This occurs on 10000-series and 12000-series platforms when removing the PS2 power supply and running system_check
None
Power supply status for PS2 is now correctly indicated when the power supply is removed.
