Storage Device

Before the DR service configuration, check whether the storage environments where the storage devices at the production and DR ends reside meet requirements. If the environments do not meet requirements, adjust the environments in time.

Common Check Items

The following check items must be checked and configured on file systems on both the production and DR ends.

  1. Check the replication relationship of the NAS file system. Asynchronous remote replication has been created between the NAS file systems at the production and DR ends and is running properly.
  2. Ensure that the NAS file systems on the storage array are working properly.
  3. Run the following command to check whether the SBC resource status in the Kubernetes cluster is normal:

    kubectl get sbc -A

  4. Run the following command to check whether the SBCT resource status in the Kubernetes cluster is normal.

    kubectl get sbct -A
