To calculate the entire capacity of a CV, use this formula. For the user-specified-CV-capacity, specify the capacity of the user area in a CV.
The resulting CV capacity is expressed in megabytes:
( ceiling ( (user-specified-CV-capacity * 15) / 672) * 672 * capacity-of-a-slot ) / 1024
where
- The value enclosed in ceiling( ) must be rounded up to the nearest whole number.
- The user-specified-CV-capacity is the capacity of the user area in a CV expressed in cylinders.
- The capacity-of-a-slot is 58 KB for all mainframe volume emulation types.
Tip:
- To calculate the capacity of the CV of 3390-V, apply the multiples of 44.8 cylinders to user-specified-CV-capacity in the upper formula. For instance, if you want to apply 44 cylinder to user-specified CV capacity, apply 44.8 cylinders. If you want to apply 45 cylinders to user-specified-CV-capacity, apply 89.6 cylinders.
- In 3390-V, the specified value is corrected to multiples of 44.8 cylinders (38,976 KB) and rounded down to the nearest whole number of cylinders.
