Dear
>It means that if the dataset is multivolume, when it expands to another >volume you can decide wether you want to use the amount of the primary >allocation or the amount of the secondary allocation to expand. >Suppose you have a dataset created with SPACE=10,5 cylinders What situation do dataset expands to another volume ? If the dataset is full, it will extent 5 cylinders. When it extent 5 cylinders,the volume is full. In this situation,does dataset expand to another volume? Then it will : >If you filled with "primary" value the dataset wil try allocations in new >volumes with 10 cylinders >If you filled with "Secondary" value the dataset will try allocations in new >volumes with 5 cylinders does it mean that if volume isn't full,dataset always extent 5 cylinders and if volume is full,dataset always extent 10 cylinders? What is benefit of Add'l Volume Amount ? Thanks again!
