I can update the firmware on the primary Teraserver, but I cannot access the target failover backup device to update is firmware. If I try to login to the backup target device, I get a note that says, "This TeraStation is a backup target for failover. To keep it working as a backup target, click 'Log Out'. To make changes, click 'Force Failover to Stop'." But if I hover over the "Force Failover to Stop" button, it says to not do this unless absolutely necessary.
Is there a different way to update the firmware on the backup target device?
