Check if necessary loopback device is available

# lsdev -C | grep loop

if nothing returned, run:

# mkdev -c loopback -s node -t loopback
loop0 Available

If the device is not present on system you get this error:

1320-003 loopmount: Specified loopback device is not found in ODM

Now for mount:

# loopmount -i /iso/dvd.iso -l loop0 -o "-V cdrfs -o ro" -m /mnt/dvd

And umount:

# loopumount -l loop0 -m /mnt/dvd

Attention: an image file can be associated with only one loopback device.

Obtain the size of the image, then identify the nearest multiple of 128 MB that will provide enough space for the image. For example, the image of CD-ROM is approximately 650/700 MB, so use 768 MB as an image size.

Make a logical volume of this size. Ensure that there is enough space on the physical volume. For example, hdisk0.

# mklv -y cdlv -s n -L /dev/cdlv rootvg 768M hdisk0

If the command fails, increase the volume size by a multiple of 128.

Use the dd command to create a pseudo-device. Ensure that the partition has enough space for the pseudo-device. In the following example command, the pseudo-device is /dev/cdlv.

# dd if=/opt/iso/cd.iso of=/dev/cdlv

Note that this command may take a long time and will create two dd processes.

Mount the device like a CD-ROM in AIX. Ensure that the mount point exists.

# mount -v cdrfs -o ro /dev/cdlv /mnt/iso
