    I checked the /etc/filesystems and there's only 1 /cdrom file system
    listed.

    IBM Tech. support also suggested removing the drive and adapter after
    they were replaced and ran cfgmgr to re-discover the devices.

    rmdev -dl cd0
    rmdev -dl scsi4 (adapter)
    cfgmgr

    I can see cd0 in the 'diag' screen. I also created the /cdrom file
    system using smitty. Not sure why I need to re-export the CD-ROM/DVD-RAM
    drive as I'm trying to mount it locally.

    Let's start with the 'diag -a' command and see what that says. Please
    send output. It appears to me as if the /dev/cd0 is mounted via NFS.
    Issue the 'mount' command to verify, and if so 'umount /dev/cd0'.
    Also,
    issue the command 'lsnfsmount'.

    Good morning to all,
    Just wondering if some of you already experienced this and found a
    solution.

    We have a pSeries server (7029-6C3), we were able to use the
    CD-ROM/DVD-RAM Drive to create mksysbs. The problem started when we
    attached an external LTO tape drive, we found out that we cannot use
    the
    same channel of the adapter internal and external (FC 6203), so we
    reconnected the library to the other channel to resolve the conflict.
    But still, the CD-ROM/DVD-RAM ceased to operate and we can't even
    mount
    it anymore.
    IBM Technician already replaced the adapter and drive and we also
    upgraded the microcode level, but still we cannot get it working, it
    can't even pass the test/diagnostics using a CD ROM test disc.

    Here's a strange error message I'm getting when I try to mount the
    /dev/cd0 to /cdrom:

    'cannot mount /dev/cd0 on /cdrom: A remote host did not respond within
    the
    timeout period'

    /cdrom file system exist.

    thanks in advance,
