Live Migration begins to migrate the volume to the destination Storage Center.
Create a Live Migration for Multiple Volumes
Use Live Migration to move multiple volumes from one Storage Center to another Storage Center with limited or no downtime.
Prerequisites
• The volumes to be migrated must be mapped to a server.
• The volumes cannot be part of a replication, Live Volume, or Live Migration.
Steps
1. If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2. Click the Storage tab.
3. In the Storage tab navigation pane, select the Volumes node or the volume folder that contains the volumes.
4. In the right pane, select the volumes that you want to migrate.
5. Right-click the volumes, and then select Live Migrate Volume.
• If one or more Replication Quality of Service (QoS) definitions exist on the source Storage Center, the Create Live Migration
wizard opens.
• If a Replication QoS definition has not been created, the Create Replication QoS wizard opens. Use this wizard to create a QoS
definition before you create a live migration for the volume.
6. Select a destination Storage Center for the live migration, then click Next.
NOTE: If Fibre Channel or iSCSI connectivity is not configured between the local and remote Storage Centers, a
dialog box opens. Click Yes to configure iSCSI connectivity between the Storage Centers.
7. (Optional) Modify Live Migration default settings.
• In the Replication Attributes area, configure options that determine how replication behaves.
• In the Destination Volume Attributes area, configure storage options for the destination volume and map the destination
volume to a server.
• In the Live Migration Attributes area, enable or disable automatic role swap. When automatic role swap is enabled, Live Migrate
swaps the roles immediately after the volume is synced. When it is disabled, you may swap the roles manually any time after the
volume is synced.
8. Click Next.
9. Verify the volumes and attributes for the Live Migration. To change any of the attributes, select a volume and then click Edit
Settings.
10. Click Create.
Live Migration begins to migrate the volumes to the destination Storage Center.
Modifying Live Migrations
Modify a Live Migration if you want to swap the source Storage Center, change Live Migration properties, or delete the Live Migration.
Swap the Source Storage Center for a Live Migration
If you did not elect to swap roles automatically, you must swap roles before completing a Live Migration.
Prerequisites
The Live Migration must be in the Ready to Be Swapped state.
Steps
1. Click the Replications & Live Volumes view.
2. On the Live Migrations tab, select the Live Migration you want to modify, and then click Swap Source Storage Center.
The Swap Source Storage Center dialog box opens.
3. Click OK to swap the source Storage Center for the Live Migration.
