镜像替代节点的根聚合（MetroCluster IP 配置）

如果更换了磁盘，则您必须镜像灾难站点上新节点的根聚合。

1. 在灾难站点上确定聚合： storage aggregate show
   示例

   cluster_A::> storage aggregate show
   
   Aggregate     Size Available Used% State   #Vols  Nodes            RAID Status
   --------- -------- --------- ----- ------- ------ ---------------- ------------
   node_A_1_aggr0
               1.49TB   74.12GB   95% online       1 node_A_1         raid4,
                                                                      normal
   node_A_2_aggr0
               1.49TB   74.12GB   95% online       1 node_A_2         raid4,
                                                                      normal
   node_A_1_aggr1   -         -     - unknown      - node_A_1         -
   node_A_2_aggr1   -         -     - unknown      - node_A_2         -
   4 entries were displayed.
   
   cluster_A::>
   
   

2. 镜像根聚合之一： storage aggregate mirror -aggregate root-aggregate
   示例
   以下示例显示了此命令如何在镜像聚合时选择磁盘并提示确认。

   cluster_A::> storage aggregate mirror -aggregate node_A_2_aggr0
   
   Info: Disks would be added to aggregate "node_A_2_aggr0" on node "node_A_2" in
         the following manner:
   
         Second Plex
   
           RAID Group rg0, 3 disks (block checksum, raid4)
             Position   Disk                      Type                  Size
             ---------- ------------------------- ---------- ---------------
             parity     2.10.0                    SSD                      -
             data       1.11.19                   SSD                894.0GB
             data       2.10.2                    SSD                894.0GB
   
         Aggregate capacity available for volume use would be 1.49TB.
   
   Do you want to continue? {y|n}: y
   
   cluster_A::>

3. 验证根聚合是否已完成镜像： storage aggregate show
   示例
   以下示例显示根聚合已完成镜像。

   cluster_A::> storage aggregate show
   
   Aggregate     Size Available Used% State   #Vols  Nodes       RAID Status
   --------- -------- --------- ----- ------- ------ ----------- ------------
   node_A_1_aggr0
               1.49TB   74.12GB   95% online       1 node_A_1    raid4,
                                                                 mirrored,
                                                                 normal
   node_A_2_aggr0
               2.24TB   838.5GB   63% online       1 node_A_2    raid4,
                                                                 mirrored,
                                                                 normal
                                                                 normal
   node_A_1_aggr1   -         -     - unknown      - node_A_1    -
   node_A_2_aggr1   -         -     - unknown      - node_A_2    -
   4 entries were displayed.
   
   cluster_A::>

4. 对其他根聚合重复执行上述步骤。
