You can perform the switchover to verify the availability of HyperMetro (NAS) for an existing recovery plan.After the switchover is successful, the primary site stops providing services and host services will be switched to the secondary site.
Prerequisites
- You have logged in to the eReplication as a user with DR management permission.
- The production site and DR site communicate with each other correctly. The management system and the DR environment at the DR site are working correctly.
- At least one recovery plan has been created in the system.
- If storage devices, hosts or VMs on production site or DR site change, storage devices, hosts or VMs at the site where a protected group resides must be refreshed, for details, refer to Refreshing Resource Information.
- The status of the recovery plan is Ready or Switchover failed.
- The running status and configuration status of the HyperMetro vStore pair on a storage array are both Normal.
- Only storage devices whose versions are earlier than V6 can be switched over.
Demands in protection objects are described as following table.
Protection Object |
Description |
|---|---|
FusionCompute VM |
After adding disks to or removing disks from a protected VM, manually refresh the information about the VM and execute the protected group where the VM resides to check whether the protected group is valid. NOTE:
For details about how to refresh the information, see Refreshing Resource Information. |
VMware VM |

If Huawei multipath software has been installed on the Linux-based DR host, ensure the configured I/O hanging time is not 0 and all virtual devices generated by the software have corresponding physical devices. For more details, see the OceanStor UltraPath for Linux xxx User Guide.
- If a recovery plan of the protection policy template is created based on HyperMetro (NAS) and the protected object type is FusionComputeVM, VMware VM, or NAS File System, perform the following operations:
- Click OK.
- If a recovery plan of the protection policy template is created based on HyperMetro (NAS) and the protected object type is FusionComputeVM, VMware VM, or NAS File System, perform the following operations:
Result
After the switchover starts, you can view the execution process and result.If the switchover fails, troubleshoot the faults and perform the switchover again.
