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 550 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 Customize
Volume Options dialog box (
), located above the Volumes pane. See ”Host Customize Dialog Box” on page 632.
NOTE: The Customize Volume Options dialog box is not available for the HP EVA.

•If you have options still selected from a previous job, clear the options you do not want in your next job. For example, assume you just mapped a volume to a port. Now you want to map the a different volume on the same host to another port. Clear the Volume and LUN panes. To clear a pane, click the 
button.
