236 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
Figure 6-57   Importing an unmanaged MDisk
The MDisk is imported and listed as an image mode MDisk in the temporary migration 
pool, as shown in Figure 6-58.

A corresponding image-mode volume is now available in the same migration pool, as 
shown in Figure 6-59.

The image-mode volume can then be mapped to the original host. The data is still 
physically present on the physical disk of the original external storage controller system 
and no automatic migration process is currently running. The original host sees no 
difference and the applications can continue to run. The image-mode Volume can now be 
handled by Spectrum Virtualize. If needed, it can be migrated to another storage pool 
later. You can use the Volume Migration wizard or manually. That action converts the 
image-mode volume to virtualized and fully managed by the system.
/SM590000Migrate to an existing pool starts by creating an image-mode volume, like the first 
method. However, it then automatically migrates the data from the image-mode volume 
onto the virtualized volume in the selected storage pool. After the migration process is 
completed, the image-mode volume and temporary migration pool are deleted. Free 
extents must be available in the selected pool so that data can be copied there.
