问题描述

集群触发警报：

::> alert show 
     (system health alert show)
               Node: node_name_03
            Resource: Shelf 3.0
            Severity: Major
       Indication Time: Fri Oct 16 17:01:21 2020
            Suppress: false
          Acknowledge: false
        Probable Cause: Storage shelf 3.0 is not connected to both controllers
                   of the HA pair (node_name-01, node_name-02).
       Possible Effect: Access to shelf 3.0 will be lost with a single
                    controller failure.
     Corrective Actions: 1. Halt all controllers that are connected to shelf 3.0.
                    2. Connect shelf 3.0 to both HA controllers following the guide applicable to your shelf.
                    3. Reboot the halted controllers.

集群将触发以下警报：
HA Group Notification from XXXXXX(Health Monitor process schm: DualControllerHa_Alert[XXXXXX]) ALERT
可以从 EMS 日志确认以下输出。
[?] Sun Oct 11 00:00:44 JST [XXXXXX: spmd: spm.mgwd.process.exit:EMERGENCY]: Management Gateway (mgwd) subsystem with ID 87957 exited as a result of signal signal 11. The subsystem will attempt to restart.
