We replaced a failed drive in Oracle Exalytics X4-4 machine. Failed drive was replaced fine and rebuild started. But when rebuild reached at 70%, the main disk got a bad sector and the rebuild failed. I tried rebuilding manually in megacli but it failed again. Oracle says that the RAID 1 volume has corrupted and the only option remains is to rebuild entire server. Server is still running and is in degraded mode. Is there any chance to survive from this situation? Can entire server rebuild be avoided? Need help....
