Based on your description, it sounds like a complete span, span 0, is down. If that's the case, then recovering this array won't be an option. You'll need to create a new one using your back up. A RAID 10 is only recoverable if one drive in the span fails. You only need to replace the failed drives, though.
Hello Community, this is an urgent issue please. We have a DELL PowerEdge R720 : Raid10 with 6HDD SAS 600GB. 3 spans are present. Two disk (Disk0 and Disk1 on the Span 0) had endured some kind of a physical damage and are out of service, removed! Disk3 is showing a S.M.A.R.T Error. PD Managements showing a foreign configuration on each hard drive. VD Managements showing No configuration present.   How can I recover from a similar situation? can I recover data by inserting 2 new drives replacing the damaged ones and importing configuration? How Can I proceed? If data is not recoverable, Can I insert 6 new disks and reconfigure my system, then install an Acronis backup image? Thank you.
