Figure 8-62 Delete Pool window
A confirmation window opens (Figure 8-63). If there are volumes with their only copy on
MDisks in the pool to be deleted, they are listed in the confirmation window. If it is safe to
delete the volumes and MDisks in this pool, even though they still might be mapped to a host,
select the Delete all volumes, host mappings and MDisks that are associated with this
pool check box and click Delete.

Figure 8-63 Confirm the deletion of the pool
In our example above we are deleting a migration pool that has an
Image Mode
MDisk in it.
This means that an external storage system is mapping a LUN to the IBM Flex System V7000
Storage Node, and this LUN is included in the MDisk Pool as an Image of the source disk
hence its content is not modified by the IBM Flex System V7000 Storage Node. It can then be
mapped to a host and later be migrated to an MDisk Pool with sufficient space. Migrating the
Image Mode disk to another Pool makes it managed by the IBM Flex System V7000 Storage
Node.
