问题描述

在重新调整测试期间，执行切回时会观察到以下情况：

Cluster_A (manual recovery required): Some disks were left behind during switchback. They are listed along with a reason for failure: 2.11.15 (no error)
 If any of these disks are failed, replace them. Otherwise use the "metrocluster switchback" command again to return the disks to their original owner. Use the "storage disk show -dr-home-id !- -fields dr-home, container-type, aggregate" command for more details on the status of the left-behind disks.

内部磁盘缺少配对节点 node_A_2 的路径
运行以下命令时，不会报告缺少的路径：

Cluster_A::> storage disk show -disk 2.11.15
                   Disk: 2.11.15
         Container Type: shared
             Owner/Home: node_A_1 / node_A_1
    
 Paths:
                                 LUN  Initiator Side      
 Controller         Initiator     ID  Switch Port         
 ------------------ ---------  -----  --------------------
 node_A_1           0n            17  N/A
