Before worrying about device special files etc, we should address a more fundamental problem. Sean's cdrom isn't being probed by the scsi driver (thus no mounts). Sean has two scsi controllers (I assume on board), ach0 and ahc1. In May, the cdrom showed up: May 11 03:10:56 user2 /kernel: cd0 at ahc1 bus 0 target 4 lun 0 May 11 03:10:56 user2 /kernel: cd0: <TOSHIBA CD-ROM XM-6201TA 1037> Removable CD -ROM SCSI-2 device May 11 03:10:56 user2 /kernel: cd0: 5.813MB/s transfers (5.813MHz, offset 15) May 11 03:10:56 user2 /kernel: cd0: Attempt to query device size failed: NOT REA DY, Medium not present But, in June it is gone: Jun 10 00:50:15 user2 /kernel: da1 at ahc1 bus 0 target 1 lun 0 Jun 10 00:50:15 user2 /kernel: da1: <IBM DDRS-39130D DC1B> Fixed Direct Access S CSI-2 device Jun 10 00:50:15 user2 /kernel: da1: 11.626MB/s transfers (5.813MHz, offset 8, 16 bit), Tagged Queueing Enabled Jun 10 00:50:15 user2 /kernel: da1: 8715MB (17850000 512 byte sectors: 255H 63S/ T 1111C) Jun 10 00:50:15 user2 /kernel: da0 at ahc1 bus 0 target 0 lun 0 Jun 10 00:50:15 user2 /kernel: da0: <IBM DDRS-39130D DC1B> Fixed Direct Access S CSI-2 device Jun 10 00:50:15 user2 /kernel: da0: 11.626MB/s transfers (5.813MHz, offset 8, 16 bit), Tagged Queueing Enabled Jun 10 00:50:15 user2 /kernel: da0: 8715MB (17850000 Sean says that the scsi BIOS sees the drive, and doesn't think there is a cabling problem. I'm scratching my head a bit here. Certainly the first priority is fixing whatever happened between May 11 and June 10 -- get the drive to be probed. I'm thinking improper termination at this point. This isn't always a deal breaker (in fact, I accidently ran my cdrom with bad termination for a few months without realizing it). Sean: could you please let us know the order the devices are on the chain. Also, please doublecheck the termination of all devices. I'm sure you've been over this a couple of times by now, but the problem is most certainly HW (IMHO of course).
