cdrecord (does not work and) gives two error messages, one about an invalid lun specifier, and one that it cannot open SCSI driver. Hardware: API UP2000 (supported according to my RH7 box). Yamaha SCSI CRW8424S writer drive connected to the single-ended (Adaptec) motherboard connector. Software: RH7, supplied 2.2.17-4 kernel, updated packages as of this morning. History: The writer was working great with RH6.1 and standard packages. Current: The drive works fine as a CD reader--I can mount an installation CD, mount it, and look through the contents. The 'sg' driver seems to be in place, according to lsmod, and working, as I can successfully use a SCSI scanner (from a NCR/Symbios adapter card--no change from when cdrecord worked on 6.1). When I do 'cdrecord -scanbus', it gives me what appears to be the correct bus,id,lun tuple (the same as I used with RH6.1). When I do 'cdrecord -checkdrive', or any other option that exercises the drive, I get an error message saying 'Invalid lun specifier' and 'Cannot open SCSI driver'. I can't see a place on this page to add an attachment, so I'll try to add cdrecord.conf, the output from lsmod, the output from 'cdrecord -scanbus', and the output from 'cdrecord -checkdrive' after filing this. (I left the priority field at normal, but this is pretty important to me, because it prevents me from making regular backups.) Thanks. Robert Riches richesr1

Created attachment 9439 [details] context diff between non-working (.~2~) and working (plain) config file.
After a little more experimenting with formatting of white space on the line that specifies the detailed drive information, I stumbled upon a way to format the line so that it works. In an ideal world, white space would be transparent, but at least there's a way to make it work. If the man page is generated by Redhat, perhaps a mention of the white space issue could be included in the man page to guide other clueless newbie users such as myself. I'll try to attach a context diff between the format that did not work and the format that did work. Depending on what you wish to do regarding possibly updating the documentation and/or possibly reporting the white space sensitivity issue to the developer, I'm okay with closing this report.
from 'man cdrecord': Each line that follows a label contains a TAB separates list of items.
