I am now on site ....
I did not get the CTRL-I prompt on boot.
Going into bios the drive config. is set to AHCI and NOT to RAID....
If I change BIOS back to RAID from AHCI ... will the RAID s/w recognize that I have a degraded RAID 1 volume or will it start from scratch and wipe my data?
I believe I'll be calling in on this............. :-/

Before getting any further, I strongly recommend doing a back up of your system to avoid losing any important data that you can need.
Now, for the system to rebuild and for the raid to work as it should you need to set the driver configuration as raid in the BIOS.
Once you do that, follow the steps at the following link to rebuild the system:
Most of the time when you replace a failed drive in a raid the rebuild will start automatically once you access Windows but if it does not do it follow the steps from the link above.
Ivan ... thanks ... my problem turned out to be more complex....
Somehow when the drive failed it appears the BIOS setting for drives reverted from RAID to AHCI ...
I reset it to RAID
This particular machine does not use the CTRL-I interface I am used to for configuring ARRAYs rather the RAID config. is buried in the advanced section of the "regular" "F1" BIOS settings...
After resetting the config to RAID I would have been able to create a RAID1 pair of drives from BIOS but it gave no indication as to whether it would mirror existing data to the new drive or create a "blank" RAID 1 array.
So I booted back into the OS and used RST which did give me two options - create a new blank array or re-mirror using the data from the remaining good drive.
I've kicked off that procedure and it is rebuilding the array.
I'm still confused on two points:
1) why the BIOS setting apparently changed its self from RAID --> AHCI
2) why the machine would not boot on the remaining good drive from the array and required the dead drive to be unplugged before it would boot...
but the customer is happy ... that's the important part ;-)

Thank you for the information ITHoser and for taking your time to share it with us, I’m glad now that your issue has been resolved.
Why the BIOS setting changes from RAID to AHCI it is strange, perhaps you will need to consult that with your motherboard manufacturer as they are more familiar with your motherboard BIOS.
As you said, the customer is happy with the system now and that is the important part.
