I have a Compaq ML530 system with a SmartArray 3200 controller and the following hot pluggable RAID configuration:
Array A:
2x9.1 gb RAID 1+0 (holds the OS)
Array B:
2x9.1 gb RAID 1+0
Array C:
3x18.2gb RAID 5 (holds data)
Five slots empty.
A disk failed on Array C. We're considering buying 3 new 36+ gb disks for a fourth array using RAID 5.
The question: Can we create the 4th array, move the data there from array C, then convert array C to Raid 1+0, or do we need to replace the 18.2 disk to fully recover array C before we can do anything with it?
