so I have a home lab, and in the beginning, I started with only 1 DISK, and in the raid config, I bypassed the raid because I didn't have 2 disks to make a RAID 10 or 1, but now, I want some redundancy, and I want to install a new identical disk. My problem is that even though I know how to set up a raid in the BIOS, if I create a new one, it will wipe the disk and all my data, and I was wondering if it was possible to make a new raid 1 but without losing the data.
My server is a HP Proliant DL380 G8 server.
Would rebuild work or would i need to use a different method?
