Fault Recovery from Production and Intra-City DR Centers to the Remote DR Center

Prerequisites

• Recovery plans have been created for protected groups.
• Data has been tested and the data generated during the test has been cleared in the remote DR center.
• If the information about storage devices, hosts, or VMs is modified at the production or DR site, manually refresh the information. For details, see Refreshing Resource Information.
• The datastore name cannot contain Chinese characters.

Procedure

1. Optional: Perform configurations before the recovery.
   • When the protected objects are VMware VMs, perform the following configurations:
     • Without configuration, the VM IP address for fault recovery is the same as that in the production center. You can configure one for fault recovery on the Protected Object tab page of the recovery plan. For details, see Self-defining Startup Parameters for a Protected Object.
     • When the asynchronous replication (NAS) DR solution is deployed, you need to create a share and configure permissions on DeviceManager of the storage array at the DR site. Permissions must be the same as those in the production center.
       

       If you fail to create a share and configure permissions, faults cannot be rectified.

   • When the type of protected objects is FusionCompute VMs, perform the following configurations:
     • Without configuration, the VM IP address for fault recovery is the same as that in the production center. You can change it for the planned VM migration on the Protected Object tab page of the recovery policy.
     • After adding or removing disks for a protected VM, refresh the information about the VM and manually enable DR for the protected group where the VM resides in time.

2. Perform a fault recovery. When selecting a DR host to take over services in the remote DR center, ensure that data is tested on the selected host.

   Fault recovery uses the latest data generated in the remote DR center to enable fast service startup at the remote DR center. Before a fault recovery, at least one recovery plan test must be executed successfully. After fault recovery, data must be checked. For details, see step 2 to step 3 in Performing Fault Recovery from the Production Center to the Intra-City DR Center.

Result

After fault recovery:

• The remote DR center provides services properly.
• The protected groups and recovery plan become invalid.
