This is a 3 drive RAID5. The disk in slot 1 failed. After the disk was replaced, I ran:

MegaCli64 -LDRecon -Start -r5 -Add -PhysDrv[32:1] -L0 -a0

Obviously that was not the correct command as now I have a degraded 4 disk raid5 instead of a good 3 disk raid5.

Is there any way to correct this?

Some more info:

Is there a reason you're using MegaCli instead of Dell OpenManage Server Administrator? MegaCli is a bit clunky to say the least. –  MDMarra Oct 16 '12 at 15:44
    
Agreed megacli is clunky. I wasn't aware of OpenManage, this is the only Dell server I have to deal with. I would rather solve this with the tools already on the server, but if OpenManage is capable of fixing this and megacli is not, then I am open to it. –  Chris Oct 16 '12 at 15:56

You can set hotspare state to disk by command: MegaCli -PDHSP -set -PhysDrv[32:1] -a0

Hot spare must be moved to rebuild state automatically. Or you can try to use this option: MegaCli -PdReplaceMissing -physdrv 32:1 -a0
