问题描述

向现有 Metrocluster 添加新的 HA 对会导致警报

::*> system health alert show
        Node: Node-01
      Alert ID: DualControllerNonHa_Alert
      Resource: Shelf 3.10
Severity: Major
   Indication Time: Fri Nov 21 13:33:33 2025
      Suppress: false
     Acknowledge: false
   Probable Cause: Storage shelf 10 is connected to two controllers
           (Node-01, Node-02) that are not an HA pair.
   Possible Effect: Access to shelf 3.10 will be lost with a single
           controller failure.
Corrective Actions: 1. Halt all controllers that are connected to shelf 3.10.
           2. Connect shelf 3.10 to both HA controllers following the guide applicable to your shelf.
           3. Reboot the halted controllers.
