Are you using hardware RAID? If so, which controller are you using?
If you're using software RAID, then which application are you using?
How do you know a disk is degraded? Do you get a message? When&where? And what does it say exactly?
Basicly, it depends on your RAID setup, please provide more information about your setup&problem.
However I can say that many modern RAID controllers automagically rebuild degraded disks in the background as the system is being used, if this is not happening then this may indicate the disk is failing.
UNIX was not designed to stop you from doing stupid things, because that would also stop you from doing clever things.
