Here's the history:
I installed a Promise TX2000 IDE RAID along with 2 drives. Booted into the BIOS of the TX2000 and defined a RAID-1 array using both drives.
Then, due to circumstances, I had to take out the card and replace it with a plain IDE controller (Promise Ultra 100).
Now when I boot I see the following in dmesg:
===snip!===
atapci1: Promise ATA100 controller port
0xef00-0xef3f,0xefa4-0xefa7,0xefa8-0xefaf,0xeff0-0xeff3,0xefe0-0xefe7 mem
0xffac-0xffad irq 11 at device 20.0 on pci0
===snip!===
ar0: 117301MB ATA RAID1 array [14953/255/63] status: DEGRADED subdisks:
0 FREE ad6: 117800MB IC35L120AVV207-0 [239340/16/63] at ata3-master UDMA100
1 READY ad4: 117800MB IC35L120AVV207-0 [239340/16/63] at ata2-master UDMA100
===snip!===
So it looks like I have an array (ar0) even though I don't have the RAID controller any more!
`atacontrol list` gives the following:
ATA channel 0:
Master: no device present
Slave: no device present
ATA channel 1:
Master: no device present
Slave: no device present
ATA channel 2:
Master: ad4 IC35L120AVV207-0/V24OA63A ATA/ATAPI rev 6
Slave: no device present
ATA channel 3:
Master: ad6 IC35L120AVV207-0/V24OA63A ATA/ATAPI rev 6
Slave: no device present
So I tried `atacontrol detach 3`. Then rebooted. The dmesg about above is from after that boot. The array is still there, but degraded. I'd like to just get rid of it and have my two drives (ad4 and ad6) to use with vinum.
This machine is running 4.5-STABLE #1, any suggestions?

I have not used a IDE RAID controler, But I do know RAID. When you
create a RAID disk the configuration of the RAID is copied to all of the
drives and the controller.
I guess, for your problem to use fdisk (8) to regenerate the MBR on one
of the disks and boot from it.
