Creating a Live Migration

Create a Live Migration for a Single Volume

Use Live Migration to move a volume from one Storage Center to another Storage Center with limited or no downtime.

Prerequisites

• The volume to be migrated must be mapped to a server.

• The volume 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 tree, select the volume.

4. In the right pane, click 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.

5. 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.

6. (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.

7. Click Create.
