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