• Each emulation type has its own maximum usable capacity. Table 32 shows the external LU's
maximum usable capacity for each emulation type.

575.98 GBOPEN emulation type other than OPEN-V
575.98 GB3380 mainframe emulation type
695.98 GB3390 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 71 shows how to determine the volume capacity using the example of the OPEN-3 case.
