Howdy :) This is my first post here, so go easy on me. winamp.com's backend db server runs 3.0, and it attached to a Seagate Sidewinder200 AIT autoloader. If the tape is mounted, backups work like a champ, but I'm so far unable to get the tape changed in the device. I'm assuming it's because the kernel recongnizes it only as a CAM device (pass4) and doesn't assign it as a changer. Any hints? Here's an excerpt from dmesg -- note that I've got two adaptec 2940UWs in here: ccd0-3: Concatenated disk drivers Waiting 5 seconds for SCSI devices to settle ahc1:A:0: Warning - unknown message received from target (0x23).
