How to know if replication has completed successfully
When the primary disk has been successfully replicated to the secondary disk, the About link on the Normal
Mode web administration page will indicate that both disks are in use.
1. Open a web browser on a PC that is on the same network as the server’s LAN.
2. Go to the server’s web administration URL. This will be at the server’s LAN IP address and port 8080. For
example, if the server’s LAN IP address is 192.168.25.254, then the correct URL to get to the web
administration home page is 192.168.25.254:8080.
3. Click on the About link on the web administration home page.
4. Look at the status of the Primary Disk and Mirror Disk. If both disks are marked “Formatted and In Use”,
then the mirror operation has completed successfully.
