Compatible PAV Capacity Values

Figure 12 (page 26)

shows the Compatible PAV capacity values that are displayed in the upper

right corner of the Compatible PAV window. The Compatible PAV Used Capacity(TB) is the capacity
(in TB) that is already used by the base volumes in the XP24000/XP20000 disk arrays. The total
available capacity for Compatible PAV in the XP24000/XP20000 disk arrays displayed in
parentheses to the right of the used capacity value, also in TB.

Figure 12 Compatible PAV Capacity Values

If the available capacity is unlimited, Unlimited is displayed.

If you are using a temporary key or the emergency key, - - - is displayed.

If the used capacity is enclosed in brackets (< >), the calculation has not been completed.

The calculation may be delayed by any of the following operations:

Assigning aliases to a new base volume and reflect the settings to XP24000/XP20000
disk arrays by clicking Apply in the Compatible PAV window.

Canceling all aliases in the corresponding CU and reflect the settings to
XP24000/XP20000 disk arrays by clicking Apply in the Compatible PAV window.

Assigning Dynamic Compatible PAV or Compatible Hyper PAV aliases to a new base
volume.

Uninstalling volumes that are used as base volumes by using LVI/LUN (VLL) or XP External
Storage.

The base volume that is recognized as the object for calculation of used capacity will not be
calculated as the used capacity if you cancel the assignment of all aliases in the corresponding
CU.

The calculation of the used capacity can be time-consuming as it is almost proportional to the
number of CUs that have volumes. It takes three minutes for each CU to calculate the used capacity.
