Get a new disk, pull the old one out, put the new one in.

These controllers are hot swapable so you can do this without powering down.

thanks for the post,.

Don't I need to initialize the disk first? Oe Again I have a PERC 3/Di controller with RAID 5 and I have 3 disks.

Dell support told me I have to do this, by initializing the drive...

This is more complicated than some of the previous comments.  I don't necessarily trust the drive light status.  They are sometimes wrong.  If you have Server Administrator installed, that will be the better diagnostic tool.  That drive light status, however, indicates a predictive failure drive.  A predictive failure drive is still participating in the array.  If it is pulled without offlining the drive, you can corrupt the array.  The best approach is to offline or "prepare to remove" the drive in Dell's OpenManage software.  Once the drive is no longer participating in the array, you can hotswap it and replace it assuming, of course, you are using a hotswap backplane.  If you do not have that software, then power the system down and remove the drive.  Then POWER THE SYSTEM BACK ON BEFORE REPLACING THE DRIVE so that the raid controller will recognize the disk is gone.  At that point, it is safe to insert the replacement hot.  Also, if you are using the OpenManage software, it should show a degraded status on that hard drive.  That status sometimes does not update when the drive is replaced.  If this happens, you should be able to do a Global Rescan from within the software to clear that status.
