This sounds familiar for some reason. On the host that has the cdrom
allocated to it, did you try deleting the cdrom filesystem, deleting the
device, run cfgmgr to rediscover the device, and then recreate the cdrom
filesystem? Re-export it and then try NFS mounting across the systems.
 
Seems I had a similar problem after a dynamic move of our DVD rom and
had to follow the above steps to get it working again.
 
 
Not sure that will help or not, but that's the only quirky thing I've
encountered that's similar.
 
Regards,
Darryl

Hello Lamar,
Here's the output:

Can you send the following:
 
grep -p cdrom /etc/filesystems
 
or see if the attribute NODE is defined in the /cdrom stanza ?
 
What did you use a the type of vfs ? Sounds like /etc/filesystems
thinks /cdrom is an NFS filesystem.

        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,
