Add or Remove Arrays from a Storage Pool

You can modify storage pools to add or remove arrays. Only one pool can be assigned to a given array. Multiple arrays can be assigned to the same pool.

You cannot add an array to an existing pool that has synchronous replication enabled.

NOTE: A pool must always have one member array.
Caution:
Exercise caution when you change a storage pool assignment because it may result in a large migration of data.
  1. Go to Manage → Data Storage.
  2. Select the pool name from the navigation tree.
  3. Go to Pool Actions → Edit.
  4. In the Edit Pool dialog box, click the green arrow next to any arrays to add them or click the red arrow next to any arrays to remove them.
    Caution:
    Removing an array from a storage pool causes any data in volumes that use the array in the storage pool to be moved to the remaining storage pool members.
  5. Click Save.
