Notes:
1.
For 3390-A, the incremental unit of the CV capacity within the first 65,520 cylinders is 1 user-cylinder, and the
incremented capacity between 65,521 and 262,668 cylinders is the 1,113 user-cylinder. Therefore, if you specify
a value that exceeds 65,520 cylinders, the value is changed to multiples of 1,113 cylinders. For instance, if 65,521
is specified, the value is changed to 65,667, which is 59 times 1,113 cylinders.
2.
For 3390-A, for the Compatible FlashCopy SE volume, if you specify a value between 1 and 40,068 cylinders,
the free space whose size is the sum of the specified value and 252 cylinders is required. If you specify a value of
40,069 cylinders or more, the free space calculated by the following formula is required.
40,320 cylinders + the value rounded up after the decimal point of *A * 1,120 cylinders
where *A = (the specified value - 40,068) ÷ 1,113 cylinders
3.
For 3390-V, the value specified in the Create LDEVs window is changed to a multiple of 44.8 cylinders (38,976
KB) and the resulting number of cylinders is truncated after the decimal point. For instance, if 10,000 is specified,
10,035 appears (224 times 44.8 cylinders is 10,035.2).
4.
When the CV of 3390-V is registered to the pool of Thin Provisioning Z, 8 GB or more free space in the CV of
3390-V is necessary. When you create a CV of 3390-V, specify the capacity as more than 9,676 cylinders.
5.
If you specify 1 cylinder to create the CV of 3390-A, actually, 1,120 cylinders are used. In 1,120 cylinders, 1,113
cylinders are defined as a user-cylinder, and 7 cylinders are defined as a control cylinder. To effectively create the
CV of 3390-A, HP recommends that you specify multiples of 1,113 cylinders for the CV capacity.
