Enable Mirroring Graphically

Note!
This operation must be performed after the database deployment is complete and mirroring has not yet been enabled.

1 Entry Point to Enable Mirroring

Log in to the UI and navigate to the "Cluster" page. Click the "Actions" button in the upper-right corner, then select "Enable mirror" to enter the mirroring setup homepage.

Note!
The "Enable Mirror" button will not appear if mirror instances already exist in the cluster.

2 Execute Mirroring Enablement

2.1 Homepage

Read the instructions carefully. After confirming that you wish to proceed, click "I acknowledge", then click the "Begin" button to begin the process.

2.2 Information Collection Page

Displays the current physical machine cluster topology, including blank machines. A blank machine refers to a host that was added during deployment but has no data segment instance assigned. Confirm the information is correct, then click "Next".

2.3 Distribution Preview Page

Shows the default planned topology for mirror segments.

2.4 Distribution Preview Page – Custom Mirror Placement

Click "Advanced Options" to enable "Customize mirror disterbution " placement. This displays the current default mirror segment configuration file.

The configuration file uses CSV format with four columns: Content ID, hostname, port number, and data directory of the mirror segment.

After modifying the configuration, click "Comfirm" to regenerate the plan. The preview will now show the customized mirror topology.

2.5 Execution Plan Page

After finalizing the mirror layout, click "Execute" to start applying the mirroring plan.

The execution may take a considerable amount of time. You can leave the mirroring setup page and use other features during this period. A progress banner will appear at the top of the page while the task runs.
Click "Details" to return to the mirroring execution page.

After the mirroring process completes successfully, click "Done" to exit the setup.
