You can view a list of the storage tiers inside a storage domain. Viewing the list allows you to check the
following:
• Information on the storage domain that contains the selected storage tier:
• - 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.
