No, this can't be done with the SAS 6/iR. You will need to do a backup/restore to a newly-created RAID 1.
Have T110 with 2 equal drives.  Only one has OS and important data on it.  Want to make the second drive a mirror or raid 1.  Is there any way to make the virtual array without loosing the data one the first disk.  Do not want to try and reload OS and data. Have no raid hardware now just the SAS 6IR controller.
Raid 0 to raid1
