Recreate a Raid volume

Hi Dell/everyone,

I have a Dell server that I unmount the raid 1 volume (with no disks connected) and converted in a regular non-raid volume with others new ssds.

I'd like to recover raid mode and/or convert that raid disks in non-raid to access the files stored on it.

Is there a way to remount raid with those hds or convert that disk to a non-raid? How can I recover the files on that hd?

I've performed some tests with one disk (to avoid risks), but I have no success.

I appreciate your help.

Renan
