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 a 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, on which you have performed the operations in Configure Cluster Service Credential, to storage system A, 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.
