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 Dell 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.
