142 Required volume capacity for emulation types
Figure 69 shows the relationship of the minimum LDEV capacity, base LDEV capacity, minimum data area
capacity, base data area capacity, and control information area capacity.
Figure 69 LDEV capacity
Figure 70 shows how to determine the volume capacity using the example of the OPEN-3 case.

Table 26 lists the minimum data area capacity, base data area capacity, and control information area
capacity for each emulation type. For the OPEN-L emulation type, CVs cannot be created. Therefore, the
base data area capacity and minimum data area capacity for OPEN-L emulation type are the same. For
the OPEN-V emulation type, the base data area capacity is not listed because there is no concept of the
base data area capacity.
