text: (cid:2) The hosts must have the storage system multipath device driver removed, and are then 
  configured for Storwize V7000 attachment. The Storwize V7000 hosts are defined with 
  worldwide port names (WWPNs) or iSCSI Qualified Names (IQNs), and the volumes are 
  mapped to the hosts. After the volumes are mapped, the hosts discover the Storwize 
  V7000 volumes through a host rescan or reboot operation. 
  
  (cid:2) IBM Spectrum Virtualize volume mirroring operations are then initiated. The image-mode 
  volumes are mirrored to generic volumes. Volume mirroring is an online migration task, 
  which means a host can still access and use the volumes during the mirror 
  synchronization process. 
  
  (cid:2) After the mirror operations are complete, the image-mode volumes are removed. The 
  external storage system LUs are now migrated and the now redundant storage can be 
  decommissioned or reused elsewhere.
