Correct me if I am wrong since I have yet to have to deal with restoring |
2 |
failed disk in an array, but in a hardware raid, with my card I would |
3 |
just enter the card's bios after rebooting and then restore the new |
4 |
replacement drive from the secondary image (remember I am using raid 10 |
5 |
with 4 disks.) Is there something I'm forgetting? |
