CD ROM

[Jeffrey F. Goldsmith]

I was asked a question this morning that I can’t answer. Hopefully someone here can give me the answer that I need.

One of my programmers wants to burn a CD with some files that they want to archive. That isn’t a problem. They also want to be able to mount that CD on to the UNIX server. That is where the problem is.

They copied the files to a CD and when we try to mount the CD it says that the device is busy. Is there something special that I need to do to create a CD that will work on a UNIX server?

Here are some of the errors:

root: / ==> mount -F cdfs /dev/dsk/c0t0d0 /cdrom
mount: /dev/dsk/c0t0d0 on /cdrom : Device busy
root: / ==> mount -r /dev/dsk/c0t0d0 /cdrom
mount: /dev/dsk/c0t0d0 on /cdrom : Device busy


Thanks for the help.

Hi Jeff,

I think it is just becaues either the cdrom drive or the CD itself.

have you tested that CD on a different Unix box ? Is it working OK on a windows PC ?

Try a different CD on the same Unix box

thanks

Here is a little more information. I am using my Windows XP computer to create the CD. The CD works on my computer and every Windows computer that I have tried. The CD does not work with my UNIX server (HP-UX 11i.23).

No, I have not tried the CD on another UNIX server because since I could not get the CD to mount I figured that it was unreadable by UNIX. We have created 3 different CDs with the same information on three different Windows XP computers and none of them work.

Other CD/DVDs (ones that I did not create) will work on my XP computer and on my UNIX server.

what software you used to burn CDs, I am using
nero 6.3.125. I know it is old but works fine for me.

Please see the attachment for options I used when I create CD/DVDs for HPUX boxes.

thanks

I found that by using a third party software I could create a CD using ISA9660 format. That was the trick.

Thanks for the help.

One of my co-workers had a copy of Easy CD Writer on their computer so I had them create a CD with the necessary files. The CD format was in ISO9660.
