192 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
The MDisk is imported and listed as an image-mode MDisk in the temporary migration
pool, as shown in Figure 4-66.
Figure 4-66 Image-mode MDisk
A corresponding image-mode volume is now available in the same migration pool, as
shown in Figure 4-67.

The image-mode volume can then be mapped to the original host mode. 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. If needed, the image-mode
volume can be migrated manually to another storage pool using volume migration or
volume mirroring later.
Migrate to an existing pool starts by creating an image-mode volume as the first
method. However, it then migrates the data from the image-mode volume onto another
volume in the selected storage pool. After the migration process completes the
image-mode volume and temporary migration pool are deleted.
