These The MegaRAID SAS controllers re called Percraid on Dell Poweredge servers. They use the MegaCLI utility, which is described here.

One of the 300GB SAS drives (for the OS) is reporting a SMART error. This disk should be replaced before it fails.

Disk swap

This is where the disk is swapped over. Once the new disk is inserted it rebuilds itself. 

# megacli -pdoffline -physdrv[32:5] -a0
                                     
Adapter: 0: EnclId-32 SlotId-5 state changed to OffLine.

Exit Code: 0x00
# megacli -pdmarkmissing -physdrv[32:5] -a0
                                     
EnclId-32 SlotId-5 is marked Missing.

Check the rebuild

You can see how the rebuild is progressing like this:
