6-1 About Migration Groups
A migration group is a group of migration source volumes that have the same characteristics (such as disk
type, RAID level, and array group) and are related to the same job.
A migration group is created by specifying filter conditions, and then registering the volumes that match those
conditions. For details on volume filter conditions, see
Volumes from one migration group cannot be included in another migration group. Volumes from a migration
group can be included in a storage tier, however.
You can specify whether a migration group is eligible for migration. If you have created a migration group that
contains a group of volumes that must not be migrated, you can prevent accidental migration by setting Can
Migrate to No.
When you delete a storage domain, the migration groups within the deleted storage domain are also deleted.
Volumes and migration tasks within the deleted migration group are not deleted, however.
If a storage domain containing a migration group is currently refreshing data, you cannot operate that migration
group. You cannot delete a migration group, add or delete a volume of a migration group, or change attribute
information for a migration group while the status of a migration task is Active or Standby.
Only the System Administrator and Storage Administrator can create, change, or delete a migration group, or
add or delete a volume. The System Administrator, Storage Administrator, and Guests who have access
privileges can reference migration groups.
You can create a migration group within a storage domain. There is no restriction on the number of migration
groups you can create within a single storage domain.
For each migration group, you can specify a migration group name, description of the migration group, and a
status indicating whether migration is enabled.
There are three methods for creating a migration group:
•
Creating an empty migration group without any volumes before adding volumes to it.
You can even create an empty migration group that does not contain any volumes. In this case, you must
add volumes after you create the migration group. See Section
.
•
Creating a migration group by searching volumes within a storage domain.
See Section
.
•
Creating a migration group by searching volumes within a storage tier.

6-2 Creating a Migration Group by Selecting Object in a Storage
Domain
You can create a migration group by selecting the Migration Groups object in a storage domain. First create an
empty migration group, and then click the Add Volume button to add a volume. For more information on the
Add Volume button and how to add a volume, see
.
To create a migration group by selecting the Migration Groups object in a storage domain:
1.
In the navigation frame, select the Migration Groups object in the storage domain in which you want to
create a migration group.
2.
In the method frame, select the Create Migration Group method.
