•Mapped - There are two types of mapped volumes:
•Masked - The volume is exposed to the storage port and to the host.
•Unmasked - The volume is exposed to the storage port, but not to the host.
•Unmapped – The volume is not exposed to the storage port. The management server puts all unmapped volumes in this category when it first discovers an array.
•Free Extents – Available free extents that can be used to create a meta volume. You can create meta volumes on EMC Symmetrix and LUSE on HDS storage systems. To create a meta volume or LUSE, select multiple free extents under the Free Extents node in the Volume pane. Select multiple LDEVS from the Free Extents menu by holding down the shift key on your keyboard and selecting free LDEVS. When you select free extents, they must of the same type. For example, on Symmetrix, you cannot select a mirrored volume and a BCV (business continuous volume) to create a meta volume.
