At first glance everything looks OK, so the answer will mean debugging:

- You did do this as user root, yes?

- The FSs/filespaces you used (/usr1/AIXADMIN/mkcd/cd_fs, ...) are large file enabled?

- The filesize ulimit is set to unlimited for this session/this user?

- Have you checked the temporary locations the command produces? What is in there? Are any of these places not what they seem to be (like being symlinked to somewhere else, etc.)?

- Have you tested your equipment to work properly (e.g. trying to burn something on the drive in question)?

- at last: have you checked the logs, especially the mentioned /var/adm/ras/mkcd.log?

Finally, this is probably not the source of your problem, but: to create ISO images: wouldn't it be easier to first burn the CD/DVD, then use

Code:

# dd if=/dev/cd0 of=/some/file.iso

To create the ISO image where you want to have it?

I hope this helps
