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.
About this task
NOTE: Live Migration is not supported on SCv2000 series storage systems.
Steps
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
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) denitions exist on the source Storage Center, the Create Live
Migration wizard opens.
• If a Replication QoS denition has not been created, the Create Replication QoS wizard opens. Use this wizard to create a
QoS denition 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 congured between the local and remote Storage Centers, a
dialog box opens. Click Yes to congure iSCSI connectivity between the Storage Centers.
6. (Optional) Modify Live Migration default settings.
• In the Replication Attributes area, congure options that determine how replication behaves.
• In the Destination Volume Attributes area, congure 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.
Live Migration begins to migrate the volume to the destination Storage Center.
