*1 The maximum number of resources that can be used as S-VOL is 48. You cannot establish any relationship if 48 resources
are already used in the S-VOL, and if the copy data range of relationships that are already established overlap with all the
resources.
*2 The maximum number of resources that can be used as S-VOL is 128.
*3 The maximum number of resources that can be used as S-VOL is 400.
*4 The maximum number of resources that can be used as S-VOL is 784.
*5 Half is for the copy source extent, and the other half is for the copy target extent.
*6 The maximum number of resources that can be used as S-VOL is 1,040.
The number of pairs that can be created is determined according to the following condition:
The maximum number of relations that can be established is the largest number that meets the
equations, Σ(α) ≤ (β) and Σ(γ) ≤ 1,048,575, where:
