When the Seagate SCSI drive is on the internal interface of the Adaptec 2100S and the TSL-S11000 Autoloader is on the external interface of the same card, the system detects the asr device properly while booting, detects sa0 for the tape drive, then (without detecting da0, the Seagate drive) it goes on to detect ch0 as the changer device. The system then prompts the user to select a valid boot device, but the da0 disk is not listed as a valid choice. If the autoloader is powered off, the system detects and boots properly from the Seagate drive. If the Seagate drive is moved to a separate SCSI controller, and the autoloader is powered back on, both devices are detected. The SCSI target ID of the autoloader is 12 and the SCSI target ID of the drive has been varied, but currently is 2. The drive is detected as a SCSI-3 device, and the autoloader is detected as a SCSI-2 device. The same computers, with exact same hardware configurations, work fine with the hard drive and autoloader on the same 2100s controller under FreeBSD release 4.10 stable. As an added note, if the Sony tape drive is connected to the bus without the autoloader, both the sa0 and da0 devices are dectected and the system boots normally. Fix: The only work-around that I am aware of is to use separate SCSI controllers for the autoloader and hard drive. How-To-Repeat: Install a 2100S Adaptec RAID controller in a system with a Seagate ST373405LC hard drive on the internal cable, with a Sony TSL-S11000 connected to the external connector of the controller, and boot the system. Same results are obtained whether booting from the hard drive or from the 6.1 distribution CD.
I'm having a similar problem with slightly different hardware.

[snip] --------------------- The puzzling thing is that the changer is on the second bus while da0 and ses0 are on the first channel (bus). Adam Ulmer
The fix for this, in my case, is to remove the asr(4) zero channel raid controller. Without the asr(4) device to muck things up, freebsd can access both scsi channels and see the hard drives on the first bus and access the lto-3 tape drive and jukebox on the second bus. This is the second time asr(4) has bitten me. Adam Ulmer
