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。
關於這項工作
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
-
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：
-
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 ----------------------------- -------------- ---------------- ---------------- 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 . . . -
確認災難站台已準備好進行切換：
「不一樣的秀」MetroCluster

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：
-
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。

執行集合體修復階段：
《修復階段集合體》MetroCluster

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

如果已更換磁碟、您必須鏡射本機與切換式集合體：
-
顯示集合體：

鏡射Aggregate：
「儲存Aggregate mirror -Aggregate Aggregate名稱」
下列輸出顯示典型的鏡射作業。

等待Aggregate重新同步；您可以使用「shorage Aggregate show」命令來檢查狀態。
下列輸出顯示許多Aggregate正在重新同步。
