If the drive is in a failed state then you can just pull the existing drive and put the new drive in. If the drive is showing predictive failure and is still online then running a consistency check in OMSA and then setting the drive to an offline state first is recommended.
Hello, I have a failed drive on a PERC 6/i.  The configuration is RAID-5.  I've replaced drives in this machine before, but always with the help of tech support.  Our warranty is now expired.  I believe I can just hot swap the drive and all will recover, though I do wonder if I'm forgetting some preparatory steps.  Do I have to do anything to prepare the machine (Poweredge T410) for a new drive? Thanks.
