Important! After promoting a non-primary Storage Domain to primary, you should
verify that the volume named PERSISTENCE has been moved to the Bricks in
the new primary domain. To verify proper migration, use the axiomcli
storage_allocation command provided by the Pillar Axiom CLI application.
When executing this command, include the -brick and -list options. For
more information, refer to the
Move a Volume to Another Storage Domain
Move a logical volume to another Storage Domain when you want to remove the
Bricks on which the volume resides or reassign those Bricks to another Storage
Domain.
The Storage Domain to which you want to reassign the logical volume must
contain sufficient free capacity of the appropriate Storage Class to hold the
logical volume.
Note: Assigning logical volumes and Bricks to a Pillar Axiom Storage Domain
must be performed as separate actions.
Tip: To avoid performance issues caused by Brick striping, move the Bricks to
the Storage Domain before you move any volumes.
1 From the Configure tab, click Groups > Storage Domains.
2 Choose Actions > Manage Storage Domains.
3 On the Volumes tab, click the Storage Domain for the logical volume that
you want to reassign.

4 In the Storage Domain drop-down list, choose the Storage Domain to which
you want to reassign the logical volume.
5 Click OK.
Result:
One of the following will occur:

● If the operation is successful, the system begins a background task to
migrate the volume to the new Storage Domain. Also, the system
releases and reconditions the storage in the previous domain.
● If the operation is unsuccessful, the system does not migrate the
volume but instead displays an appropriate error dialog:
