Red light on RAID Controller means that your server does not have connectivity to your RAID Drives. If you are using fiber connectivity on your RAID, you can try connecting via ethernet by plugging your RAID to ethernet switch and plugging your server to same switch.If you have connectivity, that shows your problem is fiber.
Restart might fix the issue,but make sure you unmount RAID volumes before you do any restart.
If it does not work, you may try pulling out your raid drives and restart ,then push raid drives back in.
I hope it helps.
