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.

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

Keep in mind the following:

•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.
