Mirroring the root aggregates of the replacement nodes

If disks were replaced, you must mirror the root aggregates of the new nodes on the disaster site.

Procedure

  1. On the disaster site, identify the aggregates which are not mirrored: storage aggregate show
    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  
                1.49TB   74.12GB   95% online       1 node_A_1         raid 4, normal
                                                                       mirrored
    node_A_2_aggr1  
                1.49TB   74.12GB   95% online       1 node_A_2         raid 4, normal
                                                                       mirrored
    4 entries were displayed.
    
    cluster_A::>
    
    
  2. Mirror one of the root aggregates: storage aggregate mirror -aggregate root-aggregate
    The following example shows how the command selects disks and prompts for confirmation when mirroring the aggregate.
    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. Verify that mirroring of the root aggregate is complete: storage aggregate show
    The following example shows that the root aggregates are mirrored.
    cluster_A::> storage aggregate show
    
    Aggregate     Size Available Used% State   #Vols  Nodes       RAID Status
    --------- -------- --------- ----- ------- ------ ----------- ------------

                                                                  mirrored,
                                                                  normal

                                                                  mirrored,
                                                                  normal
    node_A_1_aggr1  
                1.49TB   74.12GB   95% online       1 node_A_1    raid4, 
                                                                  mirrored,
                                                                  normal                                                              
    node_A_2_aggr1  
                1.49TB   74.12GB   95% online       1 node_A_2    raid4
                                                                  mirrored,
                                                                  normal
    4 entries were displayed.
    
    cluster_A::>
  4. Repeat these steps for the other root aggregates.
    Any root aggregate that does not have a status of mirrored must be mirrored.
