Note:
For 3390-A, the control information area is required for each 1,113 cylinders.
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.
