• For mainframe emulation types, LDEV capacity is an integer when converted to cylinders.
•
For 3380 mainframe volumes, 1 cylinder = 1,440 blocks
• For 3390 mainframe volumes, 1 cylinder = 1,740 blocks
•
3390-A requires a control information area every 1,113 cylinders.
•
For OPEN-L, CVs cannot be created. Therefore, the base data area capacity and minimum data area capacity are the same.
• For OPEN-V:
- The maximum capacity of LDEVs is listed as the base data area capacity.
- The capacity of the external volume is equal to the capacity of the internal volume, when 4 TB or less. This is because there
is no control information area capacity.
• For OPEN emulation types other than OPEN-V, LDEV capacity is divisible by 1,440 blocks.
Example: Determining capacity for OPEN-3 volume
The following figure illustrates capacity for an external volume with OPEN-3 emulation type. The
capacity is 1,610,612,640 blocks. Using the data for OPEN-3 in
LDEV capacities per emulation
type (page 17) , 334 LDEVS can be created from the base LDEV capacity of 4,818,240 blocks
(Base Data Area plus Control Information Area).
This results in 1,320,480 blocks of the mapped external volume becoming free space. LDEVs can
be created in free space using VLL.
