Configuring Online Takeover

Configuring Online Takeover

After configuring the online takeover function, you can enable the OceanStor 2200 V3/2600 V3 storage system (local storage system) to take over the original OceanStor storage system (heterogeneous storage system) and complete data migration and service takeover.


  • Online takeover is suitable only for the scenario where the OceanStor 2200 V3/2600 V3 storage system takes over resources of other OceanStor storage systems.
  • You can configure online takeover using either of the following methods:
    • Manual configuration

      Manually configure the takeover settings on the local and heterogeneous storage systems. For details, see Configuration Process to Clearing the Path Switchover Property of the eDevLUNs that Are Masqueraded.

    • Tool configuration

      Use the MigrationDirector tool to complete the settings automatically. Contact Huawei technical support engineers for instructions on tool usage. To obtain the MigrationDirector tool and its compatible local and heterogeneous storage systems, see OceanStor Toolkit V2R3C00 MigrationDirector for Huawei SAN Tool Operation Guide.

To master GUI-based operations, you are advised to read this document and practice the operations using the DeviceManager Demo. As a simulation program of storage system management software, the DeviceManager Demo simulates configuration and management operations on a storage system.


Do not perform the following operations until an online takeover completes.
  • Capacity expansion
  • Upgrade (including the upgrades of storage systems and UltraPath software)
  • Primary/Secondary switchover of a cluster or restart of a node in the cluster
  • Array-level UltraPath configuration
