A replication cluster uses cluster authentication credentials for identification and authentication. To improve system security, you can periodically configure the cluster authentication credentials for a replication cluster.
Procedure
- Choose Data Protection > Configuration > Replication Cluster.
- Click More on the right of the desired replication cluster and select Configure Cluster Service Credential.
The Configure Cluster Service Credential page is displayed.
- Set Pre-Shared Key Label, Pre-Shared Key, and Confirm Pre-Shared Key.
- Pre-Shared Key Label
- A pre-shared key label contains 5 to 32 characters.
- A pre-shared key label can contain only letters, digits, and underscores (_), and must start with a letter.
- Pre-Shared Key
- A pre-shared key contains 8 to 31 characters.
- A pre-shared must contain special characters (excluding <>' &") and any two types of the following characters: uppercase letters, lowercase letters, and digits.
- Pre-Shared Key Label
- Click OK.
Follow-up Procedure
After the cluster authentication credentials are modified on the remote device, you need to synchronize the modifications to the local device.
For example, if you add remote device B to storage system A and configure the cluster service credentials on storage system B, you need to synchronize the cluster service credentials of storage system B to storage system A. For details, see Modifying a Remote Device. However, if you have configured the cluster service credentials on storage system A, you do not need to synchronize the cluster service credentials of storage system A to storage system B.
