RAID restore

Question

So I logged into the Life Cycle Controller to change a Raid 0 group to RAID1.  I selected the correct disk, but after it was done it appears to have wiped the other groups that had array's  Since then I have not made any changes to the disk's that were wiped we do have backup's but can we restore these array's I saw this article that it can be done  https://www.dell.com/community/PowerEdge-HDD-SCSI-RAID/Retag-PERC-5i-RAID-5-Array/td-p/6221330   A retag is as follows (Done from the virtual disk page of PERC BIOS): 1. Delete the target virtual disk.     -F2 on the virtual disk tog get a context menu. Arrow to delete and hit enter 2. Recreate said virtual disk using the same RAID level *AND* the same stripe size      -F2 on the controller to get the context menu and create a new VD there. 3. DO NOT initialize. The initialization is what blanks out the RAID data.

Hello, as long as you do not initialize it, it seems that you can retag the RAID array without losing data. The controller and the drives both keep a copy of the RAID configuration data. If they should the same.
