Help with IDE RAID

[David Olbersen]

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 0xffac0000-0xffadffff 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?
