CHW-1885: AFF A320:「CHASSIS POWER SUPPLY NEED TO BE REPLACED」 PSU交換後のAutoSupport

問題

• AFF A320システムでは、PSUがすでに交換された後も、シャーシ内の両方のノードで電源装置（PSU）のエラーが引き続き報告されます。

• この問題の例となるイベントは次のとおりです:
  env_mgr: monitor.chassisPowerSupply.degraded:debug]: Chassis power supply X is degraded: PSU2 Volt Out is Critical High (YYYY mV)
  monitor.chassisPowerSupply.degraded:debug]: Chassis power supply X is degraded: PSUX Curr Out is Critical Low (0 mA)
  env_mgr: monitor.chassisPowerSupply.degraded:debug]: Chassis power supply X is degraded: PSU2 Power Out is Critical Low (0 W)
  env_mgr: callhome.chassis.ps.replace:debug]: CHASSIS POWER SUPPLY NEED TO BE REPLACED: PS X のコールホーム
  

• 以下は、PSUセンサーの問題を示す「system node environment sensors show」の出力例です。

  PSUX fru fault normal MULTIFAULT
  PSUX FRU Switch discrete normal normal ON
  PSUX FRU Power discrete fault normal LOW
  PSUX FRU Current discrete fault normal LOW
  PSUX FRU Voltage discrete fault normal HIGH
