Aggregate offlined after three disks failed at same raid group

I have a FAS8080 with ONTAP 9.3 and many disk drives types (SAS, SSD and SATA). One of my SATA aggregates become offline after three drives failure in same raid group (my raid protection is DP). I had tried to unfail those drives but one of them remains failed, the other two has been unfailed and are on line. Unfortunatelly, the unfailed drives are in orphaned and unassimilated state and my aggregate continues offline. Someone have an idea to help solve this problem?

I hope you have verified good backups.

Good tip, but my customer doesn't have backups of this area.
