Chapter 7. Storage Migration Wizard

4. The Storage Migration Wizard performs scanning for any new or unused MDisks
automatically and displays them in the list. Choose the MDisks you want to migrate and
click Next (Figure 7-13).
Figure 7-13 Storage Migration Wizard step 4 - Select MDisk
If the MDisks that you want to migrate are displayed in the list, select them and click Next.
IBM Flex System V7000 Storage Node then starts to import the MDisks selected. If the
MDisks that need migrating are not displayed in the list, you may need to check your zone
configuration and LUN mapping, and click Detect MDisks to run IBM Flex System V7000
Storage Node discovery procedure again.
You can select one or more MDisks as required to import, and detailed information about
the MDisk can be shown by double-clicking it.
In Figure 7-13, two LUNs are discovered as MDisks that are candidates for migration. At
this point, you may need to reference the SCSI ID information that you recorded earlier to
identify these MDisks individually. In our example, the MDisks have been selected to go
forward to the next step.
When you click Next in this step, IBM Flex System V7000 Storage Node will complete
importing the MDisks with the host’s data and a storage pool will be created.
The MDisks are added to the pool and image mode volumes (with the same size as the
MDisks) are created, which are ready for mapping back to the original hosts.
The Storage Migration Wizard creates a special migration pool that contains the copy
source and the copy destination volumes. When the Storage Migration is finished and it
has been Finalized by the administrator, then the copy source MDisk returns to an
unmanaged MDdisk and the copy destination is now part of the volume that was selected
during the Storage Migration Wizard.
Tip: If an unmanaged MDisk is manually added to a pool from the MDisks by Pool
Menu, then this MDisk becomes managed and data is striped across it.
