Hello, we just received a new r520 with the 2012r2 installed on the 500gb sas disk. I'd like to have the os on a raid 1 made up of 2 - 800gb sas drives that I have. Is there a quick way to move/migrate, the current os from the 500gb drive to the 800gb raid1?? Or do I need to do a full reinstall?
Which controller do you have?
Does the disk show up in the controller/OMSA as non-RAID/volume or as a RAID 0?
The H710 does not support non-RAID, so if you have a single disk, it must be a RAID 0. You CAN reconfigure your 1-disk RAID 0 to a 2-disk RAID 1. Just insert the disk, then use OMSA to "reconfigure" the RAID 0, choosing the new disk and RAID 1 as the target RAID level.
