Re: DVD burners and the Adaptec 2200S RAID controller...
Hi, Tnx again for your answer! Most of what you need is already in the GENERIC kernel. The rest is a available as modules. IIRC, you have to load the cam.ko module. Just use the ATAPI DVD burner via CAM. AFAICT it's very stable. I haven't burnt a coaster yet. An SCSI DVD burner is bound to be more expensive. Tnx, I'll go for an ATAPI IDE DVD burner then. Sounds like a good option and less troublesome than using a SCSI one. Cheers!

DVD burners and the Adaptec 2200S RAID controller...
Hi Roland, First off: tnx for your reply! I haven't tried burning DVDs with the ATA driver. The manual page for growisofs says that you should use SCSI devices on OpenBSD and NetBSD, but it doesn't mention FreeBSD. Hmmm, one would guess FreeBSD not to be very different in that respect. Speed is not really a concern for me, but potential data corruption is. I just read something about someone having had issues with an ATA DVD drive, due to digital line-noise on the regular low cost 40-pin ATA cable. Using an 80-pin one apparently solved it. Makes sense. I will use an Adaptec 2200S U320 RAID controller for the harddrives, so perhaps an ATA interface would be easier to configure indepenently of another SCSI device (then again: maybe not). Any advice in that respect? I don't think having CAM in the kernel will make it more difficult. If possible, I'll try to use the generic kernel. AFAIK that covers the 2200S. What I'm wondering about is the following: would it be possible to use the 2200S as a regular controller for a SCSI DVD rewriter, in combination with it running 4 drives in RAID 10 mode? The controller has two U320 channels and allows up to 30 devices to be connected to it. However, I'm not certain that is assuming RAID only set-ups or whether that also allows regular SCSI devices to be attached to it... Does anyone have any experience using such a combination? More generally: does anyone have any experiences in using the 2200S under FreeBSD? Typically enough on Adaptec's site FreeBSD is not mentioned in the list of supported OSes (surprise, surprise...). However, on FreeBSD's list(s) of supported hardware it is mentioned (besides: I currently use the 2100S successfully under FreeBSD 5.2.1, whereas Adaptec's list only mentions the 4.11 version). Can someone perhaps let me know what most closely matches such an interface? The growisofs program from the dvd+rw-tools package is the program that does the actual burning. This is probably what you want. Things like k3b and gcombust et al are just front-ends. Tnx! I'll make sure to do some RTFM-ing on those tools then. Cheers!

Most RAID cards only want disk drives on the busses anyway. Tnx, I feared as much...:( Either way: I personally like that separation as well. I have another good Adaptec SCSI controller, but I think it's a bit a pity to 'sacrifice' that just for a DVD burner (it's currently installed in a machine I have specifically set-up as MySQL database stress tester). :P Hmmm, I wonder what good ATA options there are... Otherwise, I guess I'll simply have to add another SCSI controller.

I have a 2200S under 5.3. Only disks on it though. Check the 2200S bios to see what options there are. I have a vague memory of an option for it to recognize things other than disks. Do a thorough check of your 2200S BIOS for options Chad ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
