Reuse previous disk in R740 with PERC H740P

I have a R740 configured for RAID 1 with 2 SSD drives.  I pulled the 2nd HD out and operated in degraded mode for a while.  Then I reimaged the remaining drive (still in RAID1).  Can I put the drive that I pulled out back in and boot back off of that drive?  Have been navigating through the RAID controller menus trying to figure this out, and can't seem to do so.  

Thanks!
