The V-VOL full allocation is performed in a range less than the depletion threshold size of the pool. If the capacity of V-VOLs is larger than the depletion threshold size, the full allocation operation is rejected.
Use these formulas to calculate the reserved page capacity for each pool. In the formulas, the value enclosed in ceiling( ) must be rounded up to the nearest whole number.
