Relocating aggregate ownership

You can change the ownership of an aggregate only between the nodes within an HA pair.

About this task

Steps

  1. View the aggregates on the node to confirm which aggregates to move and ensure they are online and in good condition:storage aggregate show -node source-node
    Example
    The following command shows six aggregates on the four nodes in the cluster. All aggregates are online. Node1 and Node3 form an HA pair and Node2 and Node4 form an HA pair.
    cluster::> storage aggregate show
    Aggregate     Size Available Used% State   #Vols  Nodes  RAID Status
    --------- -------- --------- ----- ------- ------ ------ -----------
    aggr_0     239.0GB   11.13GB   95% online       1 node1  raid_dp,
                                                             normal
    aggr_1     239.0GB   11.13GB   95% online       1 node1  raid_dp,
                                                             normal
    aggr_2     239.0GB   11.13GB   95% online       1 node2  raid_dp,
                                                             normal
    aggr_3     239.0GB   11.13GB   95% online       1 node2  raid_dp,
                                                             normal
    aggr_4     239.0GB   238.9GB    0% online       5 node3  raid_dp,
                                                             normal
    aggr_5     239.0GB   239.0GB    0% online       4 node4  raid_dp,
                                                             normal
    6 entries were displayed.
  2. Issue the command to start the aggregate relocation:storage aggregate relocation start -aggregate-list aggregate-1, aggregate-2... -node source-node -destination destination-node
    The following command moves the aggregates aggr_1 and aggr_2 from Node1 to Node3. Node3 is Node1's HA partner. The aggregates can be moved only within the HA pair.
    cluster::> storage aggregate relocation start -aggregate-list aggr_1, aggr_2 -node node1 -destination node3
    Run the storage aggregate relocation show command to check relocation status.
    node1::storage aggregate>
  3. Monitor the progress of the aggregate relocation with the storage aggregate relocation show command:storage aggregate relocation show -node source-node
    Example
    The following command shows the progress of the aggregates that are being moved to Node3:
    cluster::> storage aggregate relocation show -node node1 
    Source Aggregate   Destination    Relocation Status 
    ------ ----------- -------------  ------------------------ 
    node1 
           aggr_1      node3          In progress, module: wafl 
           aggr_2      node3          Not attempted yet 
    2 entries were displayed. 
    node1::storage aggregate> 

    When the relocation is complete, the output of this command shows each aggregate with a relocation status of Done.
