External LU's maximum usable capacity Emulation type
695.98 GB 3390 mainframe emulation type
According to these restrictions, you can determine the external LU's maximum usable capacity for
each emulation type. When the mapped external LU's capacity is more than the maximum capacity
of the specified emulation type, a certain part of the external LU cannot be used.
Figure 70 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 70 LDEV capacity
Figure 71 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
