Figure 8-35 Import Wizard - step 1 of 2
In Step 1 of the Import Wizard, you must decide whether the volume is imported as a generic
volume (the default) or as thin-provisioned. Caching for the volume can be disabled; it is
enabled by default.
Select Use thin-provisioning only if the volume to be imported originally was a
thin-provisioned volume that was exported to an image-mode volume.
Clear Enable Caching if you use copy services on the external storage system hosting
the LUN. It is a best practice to use the copy services of IBM Flex System V7000 Storage
Node for volumes virtualized. You can find more information about virtualizing external
storage in Chapter 7, "Storage Migration Wizard" on page 283.
