c. Click Step 2 Volume.

3. Select Meta Volume Creation from the System Action combo-box.

5. Select the storage system on which you want to create the metavolume.
HDS only: Select the storage system from which you want to create the LUSE volume.

6. Click the Step 1 button below the pane.
The selected storage system’s name is displayed below the Storage System pane.
7. In the Volume pane, select multiple free extents under the Free Extents node in the Volume pane.
The meta volume containing the selected free extents is created when the job runs.
• 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.
