• - Capacity:

• total capacity.

• used capacity (capacity of the volumes that cannot be selected as a migration target, and the ratio of

this capacity to the total capacity).

• free capacity (capacity of the volumes that can be selected as a migration target, and the ratio of this

capacity to the total capacity).

• - Number of storage tiers within the storage domain.

• Information on each storage tier:

• - Name of the storage tier.

• - Capacity of each storage tier (total capacity, used capacity, and free capacity).

• - Capacity used by each storage tier within a storage domain.

You can display the list of storage tiers in two ways:

• Select the Storage Tiers object in the navigation frame.

• Select the Object List method in the method frame.

Whether you select the Storage Tiers object or the Object List method, the List Objects-Storage Tiers

subwindow displays in the information frame, as shown in

Figure 9-1.
