更换硬件并分配磁盘后，在运行 ONTAP 9.5 或更早版本的系统中，您可以执行 MetroCluster 修复操作。然后，在所有版本的 ONTAP 中，您必须确认聚合已镜像，并在必要时重新启动镜像。
关于此任务
从 ONTAP 9.6 开始，灾难站点节点启动时会自动执行修复操作。不需要使用修复命令。
这些步骤将在运行正常的集群上执行。
步骤
-
如果您使用的是 ONTAP 9.6 或更高版本，则必须验证自动修复是否已成功完成：
-
确认 heal-aggr-auto 和 heal-root-aggr-auto 操作已完成：
MetroCluster 操作历史记录显示以下输出显示 cluster_A 上的操作已成功完成
cluster_B::*> metrocluster operation history show Operation State Start Time End Time ----------------------------- -------------- ---------------- ---------------- heal-root-aggr-auto successful 2/25/2019 06:45:58 2/25/2019 06:46:02 heal-aggr-auto successful 2/25/2019 06:45:48 2/25/2019 06:45:52 . . . -
确认灾难站点已做好切回准备：
MetroCluster node show以下输出显示 cluster_A 上的操作已成功完成
cluster_B::*> metrocluster node show DR Configuration DR Group Cluster Node State Mirroring Mode ----- ------- ------------- -------------- --------- -------------------- 1 cluster_A node_A_1 configured enabled heal roots completed 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. -

如果您使用的是 ONTAP 9.5 或更早版本，则必须执行聚合修复：
-
验证节点的状态：
MetroCluster node show以下输出显示切换已完成，因此可以执行修复。
cluster_B::> metrocluster node show DR Configuration DR Group Cluster Node State Mirroring Mode ----- ------- ------------------ -------------- --------- -------------------- 1 cluster_B node_B_1 configured enabled switchover completed node_B_2 configured enabled switchover completed cluster_A node_A_1 configured enabled waiting for switchback recovery node_A_2 configured enabled waiting for switchback recovery 4 entries were displayed. cluster_B::> -
执行聚合修复阶段：
MetroCluster heal -phase aggregates以下输出显示了一个典型的聚合修复操作。
cluster_B::*> metrocluster heal -phase aggregates [Job 647] Job succeeded: Heal Aggregates is successful. cluster_B::*> metrocluster operation show Operation: heal-aggregates State: successful Start Time: 10/26/2017 12:01:15 End Time: 10/26/2017 12:01:17 Errors: - cluster_B::*> -
确认聚合修复已完成，并且灾难站点已做好切回准备：
MetroCluster node show以下输出显示 cluster_A 上的 " 修复聚合 " 阶段已完成
cluster_B::> metrocluster node show DR Configuration DR Group Cluster Node State Mirroring Mode ----- ------- ------------------ -------------- --------- -------------------- 1 cluster_A node_A_1 configured enabled heal aggregates completed node_A_2 configured enabled heal aggregates 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. cluster_B::> -

如果已更换磁盘，则必须镜像本地聚合和切换后的聚合：
-
显示聚合：

镜像聚合：
storage aggregate mirror -aggregate aggregate-name以下输出显示了典型的镜像操作。
cluster_B::> storage aggregate mirror -aggregate node_B_1_aggr1 Info: Disks would be added to aggregate "node_B_1_aggr1" on node "node_B_1" in the following manner: Second Plex RAID Group rg0, 6 disks (block checksum, raid_dp) Position Disk Type Size ---------- ------------------------- ---------- --------------- dparity 5.20.6 SSD - parity 5.20.14 SSD - data 5.21.1 SSD 894.0GB data 5.21.3 SSD 894.0GB data 5.22.3 SSD 894.0GB data 5.21.13 SSD 894.0GB Aggregate capacity available for volume use would be 2.99TB.

对正常运行的站点中的每个聚合重复上述步骤。

等待聚合重新同步；您可以使用
storage aggregate show命令检查状态。以下输出显示许多聚合正在重新同步。

确认 " 修复根 " 阶段已完成，并且灾难站点已做好切回准备：
以下输出显示 cluster_A 上的 " 修复根 " 阶段已完成
