 Posted: Wed Mar 19, 2003 4:47 pm Post subject: cdrecord --scanbus doesn't see my CDRW on hdc |
 |
|
I have a CDRW on hdc (and dmesg confirms it), but cdrecord --scanbus only sees my USB compact flash reader. I have scsi emulation w/o ATAPI CDROM support as per the gentoo installation instructions and pass grub the "hdc=scsi-emulation" statement. I've set this CDRW up in the past on Debian and Redhat systems. Here's the output of cdrecord --scanbus:

Any ideas? Thanks for any insights/troubleshooting tips! |

| Actually, I am pretty sure you want "hdc=ide-scsi" in your grub config. Then try `modprobe ide-scsi` if that still doesn't work. |

i might be wrong, but i get this while trying to cdrecord --scanbus while my ide-scsi module isnt loaded...
so do you have ide-scsi as a module or part of the kernel?
oups sorry to repeat, i was writing while you were writing too... |

| sorry, I have "hdc=ide-scsi" in grub.conf (I was just writing without looking it up exactly). I have scsi-emulation compiled directly into the kernel. |

if your kernel is fairly recent (ie >2.4.15) you can try 'hdc=scsi' .
This is what I use and it worked fine.

| I recompiled, putting ide-scsi as a module, then modprobe ide-scsi and reran cdrecord --scanbus, but I still get the same output. I'm at a loss for how to troubleshoot this, because it seems so low-level. |

| Just gotta check. You can see the drive with `hdparm -iv /dev/hdc`, right? Need to double check that it is properly connected and powered on, at this point. |

I can't tell offhand if this is good or bad...the cd-rom functionality of the device works fine, though...

| what happens when you do "cat /proc/ide/hd?/driver" where ? is the letter of your cd drive? If it doesn't show scsi, then check /proc/ide/drivers and see if ide-scsi is even there. |

ide-scsi isn't there, but modprobe ide-scsi doesn't report any errors. /proc/ide/drivers looks like an empty file. it seems like something is blocking ide-scsi from loading but modprobe isn't notifying me.
| Code: |
localhost root # modprobe ide-scsi
localhost root # cat /proc/ide/hdc/driver
ide-cdrom version 4.59
localhost root # cd /proc/ide
localhost ide # ls -l ./
total 0
-r--r--r-- 1 root root 0 Mar 19 20:41 drivers

oh, also, lsmod shows I have ide-scsi loaded.
| Code: |
localhost root # lsmod

/proc/ide/drivers will report a zero size, but it should list at least some drivers if your cd works at all 
stuff in /proc typically doesn't report a size, as most of the stuff returned by them is generated as it is sent. |

oops, didn't realize that. here are the contents (I double-loaded ide-scsi just a second ago, but it should disappear on reboot)
| Code: |
localhost linux # cat /proc/ide/drivers
ide-scsi version 0.9
ide-scsi version 0.9
ide-floppy version 0.99.newide
ide-cdrom version 4.59
ide-disk version 1.12

one thing to check is that scsi-cdrom support is also compiled into the kernel or loaded as a module if that's your thing (as well as scsi generic I believe).
I'm not sure if it can be made to work if ide-cdrom is in the kernel with ide-scsi as a module if you try that... you're probably better off with both in the kernel or both as modules. |

thanks everyone for helping. cdrecord recognizes it now. I think atapi or something was grabbing the device before the scsi-emulation could. I recompiled again, added ide-scsi to modules.autoload and it works. funny thing is, I don't have any kernel support for atapi cdrom, so I think the ide system was grabbing it (if that's possible). why would a modularized ide-scsi work better than a built-in ide-scsi, especially if neither have to compete against an atapi-cdrom module (since I left it out)? anyway, thanks, again all!
