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. >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. >Fix: The only work-around that I am aware of is to use separate SCSI controllers for the autoloader and hard drive. >Release-Note: >Audit-Trail: >Unformatted:
