Connection Diagnosis

If a DRS instance fails to be connected to the source or destination database during connection testing, DRS provides the quick diagnosis function and returns the diagnosis result.

You can perform connection diagnosis only on the task node whose database information is obtained by entering an IP address or selecting a task node on the GUI. DN diagnosis of GaussDB is not supported.
In cluster or multi-AZ task scenarios, diagnosis can be performed only on the node of the primary task.

Prerequisites

You have logged in to the DRS console.
A task has been created.

Procedure

On the task management page, click the target task name in the Task Name/ID column.
On the Configure Source and Destination Databases page, specify source and destination database information and click Test Connection for both the source and destination databases to check whether they have been connected to the DRS instance.

If the connection testing fails, click Quick Diagnosis on the right of the failure information to diagnose the fault.
