  • ONTAP 9

问题描述

  • 启动协商切换(NSO)后、操作失败并显示错误消息
示例:
Cluster_A::> metrocluster operation show

    Operation: switchover
      State: successful
    Start Time: 5/24/2023 06:35:38
     End Time: 5/24/2023 06:35:44
      Errors: Failed to execute the switchover operation for the node components. Cluster_A (fatal): Unable to determine the result of the negotiated switchover operation for the remote nodes. Ensure the remote nodes are shut down and then retry the switchover operation with the "-forced-on-disaster true" option.
 
  • MetroCluster处于不一致状态
示例:
Cluster_A::> metrocluster node show
DR                 Configuration  DR
Group Cluster Node         State      Mirroring Mode
----- ------- ------------------ -------------- --------- --------------------
1    Cluster_A
        node_A_1       configured    enabled  negotiated switchover incomplete
        node_A_2       configured    enabled  negotiated switchover incomplete
    Cluster_B
        node_B_1       configured    enabled   negotiated switchover completed
        node_B_2       configured    enabled   negotiated switchover completed

Cluster_A::> metrocluster show

Configuration: IP-fabric

Cluster             Entry Name        State
------------------------------ ---------------------- ---------------------
Local: Cluster_A
                 Configuration State   configured
                         Mode   normal
                 AUSO Failure Domain   auso-on-cluster-disaster
Remote: Cluster_B
                 Configuration State   configured
                         Mode   normal
                 AUSO Failure Domain   auso-on-cluster-disaster

  • Aggrs已切换、但配置未切换

示例:

Cluster_A::> aggr show
...

Cluster_B Switched Over Aggregates:
Aggregate    Size Available Used% State   #Vols  Nodes       RAID Status
--------- -------- --------- ----- ------- ------ ---------------- ------------
aggr3_node_B_1
      355.5GB   334.2GB   6% online     3 node_A_1      raid_dp,
                                  mirrored,
                                  normal

 

  • 在执行NSO操作之前、切换模拟已成功完成、只需几秒钟/几分钟

示例:

Cluster_A::> met op show
  (metrocluster operation show)
    Operation: switchover-simulate
      State: successful
    Start Time: 5/24/2023 06:35:08
     End Time: 5/24/2023 06:35:24
      Errors: -
