NOTE: The S heading in the Storage Systems pane means that only a single selection is allowed.

6.Click the Step 1 button underneath the pane.

Information about the selected storage system, such as its model and IP address 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.

When you first discover a storage system, no free extents are displayed. This is because the management server puts all unmapped volumes into the “unmapped” category for the list of volumes by default. To move a volume to the free extent node, delete the unmapped volume. When the volume is deleted, it is moved to the free extents node. The free extents category is used internally by the management server. See ”Deleting a Storage Volume” on page 327 for more information.

Keep in mind the following:

•Make sure the free extents you select are not being used. Data on the free extents becomes unusable when a meta volume is created.

•You can narrow the type of volumes displayed in the Volumes pane by using the Volume

Customize Dialog (), located above the Volumes pane. See ”Host Customize Dialog” on page 404.

•If the LUN has already been selected and Step 4 is clicked, skip this step or click the button.
