Recover RAID 5 Config for Dell Power Edge r720 using PERC H310 Controller

I have got a Dell PowerEdge R720 that uses a  RAID Controller (PERC) H310. One of the drives was faulty & I replaced(via hot swap). Rebuild process was initiated automatically but after a day there was a power failure. Entered the configuration utility & under VD Management noticed that all virtual disks were wiped off & also all the old 7 physical disks are currently in foreign state except for the new one which is ready.

Under Foreign View tab 2 Virtual Disks exists & under Physical Disks there are only 2(00:01:00 & 00:01:01) & both are in foreign state whereas the rest of the 6 are marked as missing.. The second disk(00:01:01) status is rebuilding.

To change the disk status from foreign state to online I have tried to import foreign config & it fails with an error. What's the best action to take after this? If I clear foreign state will the actual data be lost or only the array will be deleted?

I need assistance in recovering the RAID 5 configuration 

 

Thanks in advance
