Normally I would suggest to do a diagnostic read dd from each disk, but you may not be able to do that with your RAID controller since it hides the individual disks.
My next recommendation would be a full AC cycle; can you power the host off for a few minutes? It's a bit cargo cult-y but sometimes it works. It may also help (or not) for you to spin around 3 times while the machine is off.
