Migrate/Extend raid1 volume to larger disks on Dell PowerEdge 2950 with perc 6/i – OMSA

I have a dell PowerEdge 2950 with perc 6/i running raid1, there were 2 250GB drives in which have been replaced (one at a time) with 1TB drives.

So now I have the a virtual disk that is 232.25GB and 698.75GB (Free) that I would like to extend/reconfigure the virtual drive to utilize.

From what I understand my plan was to do the following:

• Take a full backup. DONE!
• Replace the drives one by one and wait for a rebuild to complete.
  DONE!
• Use Dell OpenManage Server Administrator to extend the size of the
  physical RAID 1 volume on the disk from 232.25GB to full 1TB, using
  the reconfigure option Here is where I'm running into an issue
• Extend the partitions in Windows…

When running the Reconfigure it only has Raid0 as an option with the 464.50GB min/max Listed… I am not sure whats going on here.

Here are screens of the options:
omsareconfig

Any help getting this sorted would be greatly appreciated!
