8.2.2 Importing MDisks
LUNs hosted on external storage systems can be migrated into IBM Flex System V7000
Storage Node storage. Hosts, which used to be directly attached to those external storage
systems, can continue to use their storage that is now presented by the IBM Flex System
V7000 Storage Node instead.
Storage Node storage. Hosts, which used to be directly attached to those external storage
systems, can continue to use their storage that is now presented by the IBM Flex System
V7000 Storage Node instead.
To achieve this configuration, the existing external LUNs must be imported as an
image-mode
volume
using the Import option. This action is possible for unmanaged MDisks only. Those
disks must not have been added to a pool, as described in 8.2.1, “Adding MDisks to storage

If the Import option is used and no existing storage pool is chosen, a temporary
migration
pool
is created to hold the new image-mode volume. This image-mode volume has a direct
block-for-block translation from the imported MDisk to the volume presented from now on by
