Q: How do I force a Mac Pro Lion RAID 5 rebuild after replacing a failed drive?
I have a Mac Pro with a Hardware RAID card with 4 identical drives attached.
1 drive failed. I replaced it with an identical drive. It has never rebuilt the array with the new drive.
How can I force the rebuild so I'm protected and the array is operating at full speed?
Mac Pro, Mac OS X (10.7), Hardware RAID card set to RAID 5

Finally discovered the elusive answer on my own.
First one has to select the newly added drive and use the RAID Utility to Make (that new drive) Spare.
As soon as that's done successfully, the system recognizes the Spare and Assigns it to the RAID Array.
Then, it automatically schedules a Task to begin the Rebuild.
Problem solved.
