Figure 19 Example of External Volume of 2 TB or Less

• You cannot access the data that is stored in the ﬁeld over the maximum capacity of the external

volume.

The maximum volume capacity differs depending on the emulation type that you specify at the

external volume mapping. See “Required Volume Capacity for Each Emulation Type”on page127

for more details.

• When an external volume is mapped as internal volume(s) with the setting of the emulation type

other than OPEN-V, the number of volumes and the volume capacity of the mapped external

volume(s) depend on the capacity of the original external volume and the basic capacity of each

emulation type. When an external volume is mapped with the setting of emulation type other

than OPEN-V, the data management information area is required to be provided in the mapped

volume. This means that the capacity that can be used after the mapping becomes smaller

than the actual external volume capacity. The available capacity decreases as much capacity

as the data management information area.

Figure 20 on page 46 showsanexample of thecasethatthe original capacity of theexternal

volume is bigger than the basic capacity of the emulation type. In Figure 20 on page 46, the

emulation type is OPEN-3. Figure 21 on page 47 shows an example of the case that the original

capacity of the external volume is smaller than the basic capacity of the emulation type.
