Inheritted a system with a 3ware LSI 9750-8i having five disks and RAID-5. I see a message about "RAID-5 INOPERABLE" for u1 but see no disk failure for the only disk (p1) in the unit.

I don't quite get what is going on here and I am not seeing any errors in the logs or the operation of the system either.
I suspect that u1/p1 is the spare. Am I right? Do I need to replace the p1 disk and rebuild the u1 array? Or just try to rebuild the u1 array?
The User Guide I have, is silent about what to do in this case.
