NS-120 Celerra Excitement

After a recent power outage, one of the 1TB Sata drives in a Raid-5 died, not a big deal. However, one of the Hot-Spare 300GB FC drives took over for it. We are nearly full allocated space-wise, so this is a scary thing. We do have a 1TB identical Hot-spare in the chassis, so my rep told me to just yank the FC Hot-spare drive that was now part of the raid (and had been for 5 days). Luckily this worked perfectly, pulling the drive forced the Celerra/Clariion to Transfer the data to the correct Hot-spare and after the new drive arrived everything went back to how it should be.
