Configuring volumes in a parity group

The Delete LDEV and Create LDEV functions are performed on each parity group. Parity groups are also separated from each other by boundary limitations. Therefore, you cannot define a volume across two or more parity groups beyond these boundaries.

As the result of creating and deleting LDEVs, a parity group contains CVs and free spaces that are delimited in logical cylinders. Sequential free spaces are combined into a single free space.
