  • CriticalPSUFruOffAlert ヘルスアラートのノードレポート:
ClusterA::> system health alert show -instance
            Node: Node-01
          Monitor: chassis
          Alert ID: CriticalPSUFruOffAlert
     Alerting Resource: xxxxxxx
         Subsystem: Environment
        Indication Time: Fri May 20 02:08:21 2022
             Severity: Critical
         Probable Cause: Loss_of_redundancy
           Description: PSU1 is off. The nodes in this chassis are Node-01, Node-02.
     Corrective Actions: 1. Check PSU1 and switch it on.
                     2. Refer to the Hardware specification guide for more information on the position of the                              power supply unit (PSU) and ways to check or replace it.
                     3. Contact support personnel if the alert persists.
