I have SQL 2008 servers. I have researched which RAID config to use, and decided to go with RAID-1.
This is since speed is not a major issue, while data protection is.
My question is: Once you setup RAID-1. Say later on, you get a HD failure. What do you have to do to recover?
Thanks,

If a drive fails you would need to replace the drive and rebuild your raid array using the RAID console.

With RAID 1, when you have a HD failure, the other HD continues to function as a single drive until the failed drive is replaced. What you need to do is:
1 Order a new HD
2 Shut down the server
3 Replace the failed HD
4 Power up the server
The RAID controller will automatically recreate your RAID 1.
