Use this tab to specify the hot spare pool requirements for the new volume.
A hot spare pool is a set of slices that can be automatically swapped into your volume to replace failed slices. A hot spare should be the same size or larger than the components of the volume you are creating. If the hot spare is larger than the component it replaces, the extra space on the spare will be wasted.
If you do not want to use a hot spare pool, choose No Hot Spare Pool.
If you have an existing hot spare pool that you want the new volume associated with, choose Use Existing Hot Spare Pool
If you need to create a new hot spare pool with which this volume should be associated, choose Add New Hot Spare Pool
