What Can I Do If the Remote Backup Service Fails Due to a Low Link Bandwidth Between Storage Systems or Inefficient Concurrency When Both HyperMetro and Remote Backup Services Are Created?
Answer
When the host service bandwidth is higher than the replication network bandwidth between the storage systems or the replication network provides a low concurrency, the service with a high priority is preferentially processed. In the preceding scenario, the link bandwidth is too low. As a result, the service with a low priority fails.
HyperMetro takes precedence over asynchronous remote replication.
Perform the following operations:
- Increase the replication link bandwidth or the number of replication links to ensure that the replication network bandwidth is higher than or equal to the peak service bandwidth.
- Check whether the remote backup service is normal.
- If the remote backup service is normal, no further action is required.
- If the remote backup service is abnormal, contact Huawei technical support.
