I have a DELL server with an integrated PERC H700 and 2 disks in RAID1 (mirroring) for the Operating System and a SAN.
I need to test another operating system maintaining the existing one. I would like to:
- break the current raid
- place in safe one of the two hd's with the OS i want to maintain
- use the other hd to install a new os
- rollback to previous OS using the original hd, recreate the RAID1.
Ok, I could make an image, store it in a safe place, reinstall the os then rollback using the image but is not easy to create an image with a raid configuration 'in the middle'.
The doubt is how to correct break the raid, and how the raid will be recreated (disk 1 over disk 0? vice versa? the coltroller asks for this?).
