Why is there a Default Partition in a "Non-Partitioned" Library?

All resources (drive bays, storage cells, and CAPs) within the SL4000 library must always be contained within at least one partition. Therefore, at a minimum there is always a default partition.

In a non-partitioned library (meaning a library with partitioning disabled), there is a single default partition that contains the entire library. Initially, this partition is named "DefaultPartition", but you can rename or edit its partitioning attributes at anytime.
