Resetting a Cluster Authentication Credential

Scenarios

DR clusters use the cluster authentication credentials for identification and authentication. To improve the system security, you can periodically reset the cluster authentication credentials for DR clusters. After resetting a cluster authentication credential, you need to change the remote cluster authentication credential of the corresponding remote device in the remote system.

Prerequisites
You have logged in to FusionStorage Block Self-Maintenance Platform.
Procedure

    Reset a cluster authentication credential.

    1. On FusionStorage Block Self-Maintenance Platform, choose DR Service > dr > DR Cluster.
    2. Locate the row that contains the target cluster and click to unfold the cluster details.
    3. On the Service Cluster tab, click Reset Cluster Authentication Credential.

      The Reset Cluster Authentication Credential page is displayed.

    4. Set the new pre-shared key and pre-shared key label.

      The DR cluster performs cluster identity authentication through cluster authentication credentials. When creating a remote device, enter the authentication credential of the remote cluster.

      • Pre-shared Key Label: Marks the cluster pre-shared key. The field cannot be empty. It must be a string of 5 to 32 characters starting with a letter and can contain uppercase letters, lowercase letters, digits, and underscores (_).
      • Pre-shared Key: Used together with the pre-shared key label for identity authentication. The field cannot be empty. It must be a string of 8 to 31 characters and must contain special characters and two of the following types of characters: uppercase letters, lowercase letters, and digits. Identical characters cannot be used for three consecutive times. The pre-share key and pre-shared key label cannot be the same or in reverse order.

    5. Click Modify.

      A warning dialog box is displayed.

    6. Click Yes.

      A dialog box is displayed indicating that the operation is successful.

    7. Click OK.

    Change the remote cluster authentication credential of the remote device.

    After resetting a cluster authentication credential, you need to change the remote cluster authentication credential of the corresponding remote device at the remote site. The following operations are performed on the remote FusionStorage Block Self-Maintenance Platform.

    1. On FusionStorage Block Self-Maintenance Platform, choose DR Service > dr > DR Cluster.
    2. Locate the row that contains the target cluster and click to unfold the cluster details.
    3. On the Remote Device tab, locate the row that contains the target remote device and click Change Remote Cluster Authentication Credential.

      The Change Remote Cluster Authentication Credential page is displayed.

    4. Enter the new pre-shared key and pre-shared key label for the remote cluster.
    5. Click OK.

      A dialog box is displayed indicating that the operation is successful.

    6. Click OK.

      The cluster authentication credential has been changed.

Expanding the Capacity of a Service Cluster

Scenarios

When the capacity of a service cluster cannot meet the requirements, you can expand the capacity of the service cluster. After the capacity expansion is complete, you need to add the IP addresses to the corresponding address pool.

Prerequisites
  • You have configured the replication plane and installed the operating system (OS), FusionStorage Agent (FSA), block storage client, DR component, and KV client on the to-be-expanded DR nodes. For details, see Installation and Configuration.
  • You have installed the operating system (OS), FusionStorage Agent (FSA), and replication component on the to-be-expanded DR nodes. In addition, you have created the block storage clients and KV clients on these nodes. For details, see Installation and Configuration.
  • You have logged in to FusionStorage Block Self-Maintenance Platform.
Procedure

    1. On FusionStorage Block Self-Maintenance Platform, choose DR Service > dr > DR Cluster.
    2. Locate the row that contains the target cluster and click to unfold the cluster details.
    3. On the Service Cluster tab, click More and choose Expand Capacity.

      The Expand Capacity page is displayed.

    4. Click Select.

      The IP Address List page is displayed.

    5. Select the servers to be expanded and click OK.

      The Expand Capacity page is displayed.

    6. Click OK.

      A dialog box is displayed indicating that the operation is successful.

    7. Click OK.

      After the service cluster expansion is complete, add the IP addresses to the corresponding address pool. For details, see Modifying an Address Pool.

Reducing the Capacity of a Service Cluster

Scenarios

When a DR node needs to be removed from a service cluster, you can reduce the capacity of this service cluster. After the capacity reduction is complete, you need to remove the IP addresses from the corresponding address pool.

Prerequisites
You have logged in to FusionStorage Block Self-Maintenance Platform.
Procedure

    1. On FusionStorage Block Self-Maintenance Platform, choose DR Service > dr > DR Cluster.
    2. Locate the row that contains the target cluster and click to unfold the cluster details.
    3. On the Service Cluster tab, click More and choose Reduce Capacity.

      The Reduce Capacity page is displayed.

    4. Click Select.

      The IP Address List page is displayed.

    5. Select the servers to be reduced and click OK.

      The Reduce Capacity page is displayed.

      After the capacity reduction, the service cluster cannot contain less than three replication nodes.

    6. Click OK.

      A dialog box is displayed indicating that the operation is successful.

    7. Click OK.

      After the service cluster reduction is complete, remove the IP addresses from the corresponding address pool. For details, see Modifying an Address Pool.

Deleting a Service Cluster

Scenarios

If the DR services in the DR cluster are no longer used, you can delete the service cluster.

Prerequisites
  • All HyperMetro services, including HyperMetro pairs, remote devices, address pools, and service clusters, have been deleted from the cluster.
  • All remote replication services, including remote replication pairs, remote devices, address pools, and service clusters, have been deleted from the cluster.
  • You have logged in to FusionStorage Block Self-Maintenance Platform.
Procedure

    1. On FusionStorage Block Self-Maintenance Platform, choose DR Service > dr > DR Cluster.
    2. Locate the row that contains the target cluster and click to unfold the cluster details.
    3. On the Service Cluster tab, click Delete Cluster.

      A warning dialog box is displayed.

    4. Click Yes.

      A dialog box is displayed indicating that the operation is successful.

    5. Click OK.
