(redirected) Physical disk failed-what next?

One of our R710's has a drive being reported as 'failed'-is there anything that has to be done before swapping it? Here's a brief summary of our configuration:

• PERC 6/i controller
• Drives configured in a RAID 5 with hot spare-hot spare was put in place over the weekend.
• Firmware version-6.2.0-0013
• Driver version-4.05.01.64
• Storport Driver Version-6.1.7601.17577

This is a production server, so whatever needs to be done can't be disruptive, or I'll have to wait until COB.

Thank you in advance for any help you can offer.
