If you select to enter a volume quantity to determine the amount of storage you want to configure, you must enter/select an integer value.
You need to define/select at least two of the three storage configuration values: 1. amount of unused storage to configure [percent or gigabyte], 2. volume size, or 3. volume quantity.
After defining at least two of these, you must click the Calculate button to automatically fill-in the remaining value of three configurable values. If all three choices are filled in, then calculating will overwrite volume size, based on the amount of unused storage to configure and the volume quantity. Note that you must enter only integer values into the fields: remove all spaces, decimal points, or other nonnumeric characters.
Enter an integer value for the volume size you want to configure.
