I have a ProLiant server with SBS2008 using a Smart Array P410i in a RAID 1 (+0). The existing configuration uses slots 1 and 2 each with 250Gb drives as Mirror Group 1 and slots 3 and 4 with the same drives as Mirror Group 2. In addition, slot 5 has an Active Spare with the same drive size. The drive in slot 4 has failed and is flagged as dead.
I would like to change the entire arrangement to 2- 1Tb drives in a RAID 1 arrangement with a third drive (1TB) as an active spare. These drives are of the exact same family as the originals, just larger.
Is this possible, and what are the steps to achieve it?
