    Strange problems with RAID. If disks are located on different controllers
    after rebooting one of disks disappears. Disks on one controller coexist in
    RAID normally.

    Any ideas? Please, help!

    cf# atacontrol status 0
    atacontrol: ioctl(ATARAIDSTATUS): Device not configured
    cf# atacontrol create mirror ad1 ad4
    ar0 created
    cf# atacontrol status 0
    ar0: ATA RAID1 subdisks: ad1 ad4 status: READY
    cf# fastboot

    cf# atacontrol status 0
    ar0: ATA RAID1 subdisks: ad1 DOWN status: DEGRADED

    In dmesg:

    ad0: 76319MB <ST380011A> [155061/16/63] at ata0-master UDMA66
    ad1: 76319MB <ST380011A> [155061/16/63] at ata0-slave UDMA66
    ad2: DMA limited to UDMA33, non-ATA66 cable or device
    ad2: 76319MB <ST380011A> [155061/16/63] at ata1-master UDMA33
    ad4: 76319MB <ST380011A> [155061/16/63] at ata2-master UDMA100
    ad6: 76319MB <ST380011A> [155061/16/63] at ata3-master UDMA100
    ar0: WARNING - mirror lost
    ar0: 76319MB <ATA RAID1 array> [9729/255/63] status: DEGRADED subdisks:
     disk0 READY on ad1 at ata0-slave
     disk1 DOWN no device found for this disk

    Similarly for ad2 and ad6.

    Other situation with same controller:

    cf# atacontrol status 0
    atacontrol: ioctl(ATARAIDSTATUS): Device not configured
    cf# atacontrol create mirror ad1 ad2
    ar0 created
    cf# atacontrol status 0
    ar0: ATA RAID1 subdisks: ad1 ad2 status: READY
    cf# fastboot

    cf# atacontrol status 0
    ar0: ATA RAID1 subdisks: ad1 ad2 status: READY

    Similarly for ad4 and ad6.

    cf# uname -a
    FreeBSD cf 5.1-RELEASE-p5 FreeBSD 5.1-RELEASE-p5 #0: Mon Sep 22 07:46:00 GMT 2003 tsypa@cf:/usr/obj/usr/src/sys/GENERIC i386
    cf#

    Some dmesg about controllers:

    atapci0: <Promise PDC20269 UDMA133 controller> port 0xdf90-0xdf9f,0xdfe0-0xdfe3,0xdfa8-0xdfaf,0xdfe4-0xdfe7,0xdff0-0xdff7 mem 0xfeafc000-0xfeafffff irq 11 at device 8.0 on pci2
    ata2: at 0xdff0 on atapci0
    ata3: at 0xdfa8 on atapci0

    atapci1: <Intel ICH UDMA66 controller> port 0xffa0-0xffaf at device 31.1 on pci0
    ata0: at 0x1f0 irq 14 on atapci1
    ata1: at 0x170 irq 15 on atapci1

    Igor.
