Explanation

You are attempting to add one or more resources to a capacity pool, but the resources are already assigned to another capacity pool. Some of the resources are directly assigned to a capacity pool, and some are indirectly assigned to a capacity pool at the storage system level. If you continue, the resources will be reassigned to the capacity pool you specified.
