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) denitions exist on the source Storage Center, the Create Live Migration
wizard opens.
• If a Replication QoS denition has not been created, the Create Replication QoS wizard opens. Use this wizard to create a QoS
denition 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 congured between the local and remote Storage Centers, a dialog box
opens. Click Yes to congure iSCSI connectivity between the Storage Centers.
