Changing clusters of DDHs

After you create a DDH cluster, you can add or remove DDHs in the cluster, or change the cluster of a DDH. This way, you can manage DDHs by group.

Prerequisites

The DDH to be added must be in the same region and availability zone as the target cluster.

On the "Host cluster" tab, use either of the following methods to go to the page for adding hosts.

Click the "Add host" button in the "Actions" column of the target cluster.

Click the cluster name to enter the cluster details page, and then click the "Add host" button on the "Added hosts" tab.

Select the DDH to be added, and then click the "Confirm" button to complete the operation.

If no DDHs are available, create a DDH first.

Remove a DDH

Log in to the DDH console.

In the top menu bar, select the region where your business is located.

On the "Host cluster" tab, click the cluster name to enter the details page, and then click the "Remove from host cluster" button on the "Added hosts" tab.

Select the DDH to be removed, and then click the "Confirm" button to complete the operation.

Change a host cluster
