Capacity list for each emulation type
This section explains the LDEV capacity and volume capacity for each emulation type in the units of
blocks and cylinders.
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.
In this section, the numbers of cylinders are calculated from the following formulas.
For 3380 mainframe volumes: 1 cylinder = 1,440 blocks
For 3390 mainframe volumes: 1 cylinder = 1,740 blocks
