執行Aggregate修復及還原鏡像(MetroCluster 知識IP組態)

更換硬體並指派磁碟之後、在執行ONTAP 《S還原9.5或更早版本的系統中、您可以執行MetroCluster 《還原作業(S還原):在ONTAP 所有版本的支援中、您必須確認集合體已鏡射、並視需要重新啟動鏡射。

從ONTAP 功能支援的9.6開始、災難站台節點開機時、系統會自動執行修復作業。不需要使用修復命令。

這些步驟會在正常運作的叢集上執行。

步驟
  1. 如果您使用ONTAP 的是更新版本的版本、則必須確認自動修復已成功完成:

    1. 確認已完成修復-恢復-自動和修復-根- agg-auto自動作業:

      《不穩定營運歷史》MetroCluster

      下列輸出顯示叢集A上的作業已成功完成

      cluster_B::*> metrocluster operation history show
      Operation                     State          Start Time       End Time
      ----------------------------- -------------- ---------------- ----------------

                                                                    2/25/2019 06:46:02
      heal-aggr-auto                successful     2/25/2019 06:45:48
                                                                    2/25/2019 06:45:52
      .
      .
      .
    2. 確認災難站台已準備好進行切換:

      「不一樣的秀」MetroCluster

      下列輸出顯示叢集A上的作業已成功完成

    cluster_B::*> metrocluster node show
    DR                          Configuration  DR
    Group Cluster Node          State          Mirroring Mode

                  node_A_2      configured     enabled   heal roots completed
          cluster_B
                  node_B_1      configured     enabled   waiting for switchback recovery
                  node_B_2      configured     enabled   waiting for switchback recovery
    4 entries were displayed.
  2. 如果您使用ONTAP 的是版本號不超過版本的版本、則必須執行Aggregate修復:

    1. 驗證節點的狀態:

      「不一樣的秀」MetroCluster

      下列輸出顯示切換已完成、因此可以執行修復。

      cluster_B::> metrocluster node show
      DR                               Configuration  DR

      4 entries were displayed.
      
      cluster_B::>
    2. 執行集合體修復階段:

      《修復階段集合體》MetroCluster

      下列輸出顯示典型的Aggregate修復作業。

      cluster_B::*> metrocluster heal -phase aggregates
      [Job 647] Job succeeded: Heal Aggregates is successful.
      
      cluster_B::*> metrocluster operation show
        Operation: heal-aggregates

           Errors: -
      
      cluster_B::*>
    3. 確認Aggregate修復已完成、且災難站台已準備好進行切換:

      「不一樣的秀」MetroCluster

      下列輸出顯示叢集A上的「修復集合體」階段已完成

    cluster_B::> metrocluster node show

    4 entries were displayed.
    
    cluster_B::>
  3. 如果已更換磁碟、您必須鏡射本機與切換式集合體:

    1. 顯示集合體:
