I am trying to install bos.data file set on AIX 7.1..
$oslevel -s
7100-04-02-1614

I tried the following loopmount command, but it failed.
The error code is 1320-002, whose explanation is nowhere to be found.
$ sudo loopmount -i /work/AIX/CZN6JML.iso -o "-v cdrfs -o rw" -m /mntcd
1320-002 loopmount: Failed to read Customized Database in ODM

Can anybody help me out?

Take a look at this technote first https://www.ibm.com/support/pages/loopback-device-support-aix

And also check that the ODMDIR environment variable points to the correct location.

# env | grep ODM
ODMDIR=/etc/objrepos

Also, try it without sudo i.e. try it directly as the root user.

Hi Chris,

Problem solved!

So I tried the same command with root user, and the error message has changed.
# loopmount -i /work/AIX/CZN6JML.iso -o "-v cdrfs -o rw" -m /mntcd
1320-007 loopmount: Failed to mount the imagefile

The new message is listed in the page you shared, and I followed the instruction: Check the mount options. Readonly must be supplied.
This worked.
# loopmount -i /work/AIX/CZN6JML.iso -o "-v cdrfs -o ro" -m /mntcd

Thank you for helping me!

Try it with these options: -o "-V cdrfs -o ro"   (Upper case "V" and "ro". You don't need write to the cdrom FS, right?)

Hi Mackey,

Would you kindly tell me the difference between "V" and "v"?
I looked into the loopmount command page but have no clue. I am actually an application developer and have no knowledge of loopmount command... I was using the command shared by an infrastructure team member. 

And no, i dont need to write to the CD rom file system. I was basically trying to create /usr/share/dict/words
