I have a PowerEdge 2900 III with a PERC 6/i Controller. The PERC has 2 arrays, each one with 3 hard drives and each hard drive is the same size/speed (146GB 15K rpm SAS).
I would like to delete the second array and add those disks to the first, so we have a single 6-disk RAID 5 array. Then I'd like to convert the array to RAID 6.
Is this possible without losing any data on the first array?
