Interoperability with Volume Migration

Supported functions:

• Using a V-VOL as a migration source or a migration target.
• The maximum capacity of a V-VOL used as a migration source or target is the same as the maximum capacity of a V-VOL.

Not supported functions:

• Using on pool-VOLs.
• Increasing the capacity of V-VOL used by Volume Migration.
• Reclaiming zero pages of V-VOL used by Volume Migration.
• Using on a deduplication system data volume.
• Deleting the DRD-VOL with capacity saving enabled used by Volume Migration.
• Initializing duplicated data for the pool containing the DRD-VOL with capacity saving enabled used by Volume Migration.

In addition, you can use Dynamic Provisioning in combination with Volume Migration to migrate V-VOLs.

You cannot specify a Dynamic Provisioning pool-VOL as a Volume Migration source volume and target volume.

If you specify the V-VOL as the source volume, you must not specify the V-VOL that uses the same pool of the source volume.

For more information about the migration of V-VOLs used in the following software products, see VSP One Block Volume Migration User Guide.

• TrueCopy
• Universal Replicator
• A V-VOL used in a GAD pair cannot be migrated.

This figure shows the interaction when the Volume Migration source volume and target volume are also DRD-VOLs.

This table shows the combinations of DRD-VOLs supported when Dynamic Provisioning is used with Volume Migration to migrate DRD-VOLs.
