Importing Mdisks - IBM V7000 Introduction And Implementation Manual

After you click Delete, data migration from the MDisks to be removed starts. You can find the
migration progress in the Running Tasks status indicator (Figure 8-33).

8.2.2 Importing MDisks

LUNs hosted on external storage systems can be migrated into IBM Flex System V7000
Storage Node managed storage. Hosts, which used to be directly attached to those external
storage systems, can continue to use their storage that is now presented by IBM Flex System
V7000 Storage Node instead.
To achieve this configuration, the existing external LUNs must be imported as an
volume
disks must not have been added to a pool, as described in 8.2.1, "Adding MDisks to storage
pools" on page 337.
If the Import option is used and no existing storage pool is chosen, a temporary
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
IBM Flex System V7000 Storage Node and existing data is being preserved.
