The power supply or motherboard is giving trouble on MSSQL10's node and it was also the only server running on it, so moving it to a better node is the best option.
We've got all completed and done looking good now. The main reason for needing that reboot was because the backup drive wasn't being detected as it was added later (since we wanted to get the server up asap with core live data).
now with the drivers updated we can add and remove without further rebooted.
