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 361 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 448.
• If the LUN has already been selected and Step 4 is clicked, skip this step or click the
button.

Keep in mind the following:
• If you have options still selected from a previous job, just clear the options you do not want in

volume on the same host used previously. Just clear the Volume pane. To clear a pane, click the
button.
