====== AIX: Mount ISO Image (after AIX6.1TL4)======

Mount directly the iso file on /mnt:
<cli prompt='#'>
# loopmount -i cdrom.iso -o "-V cdrfs -o ro" -m /mnt
</cli>


Mount directly the UDF file on /mnt (!latest iso from VIOS is an UDF format!):
  Example of error with bad format
  # cp mksysb_image /export/lppsources/vios_4_1_0_21_mksysb
  cp: mksysb_image: A system call received a parameter that is not valid.

<cli prompt='#'>
# loopmount -i VIOS_31010_Flash.iso -m /mnt -o "-V udfs -o ro"
</cli>

When done, unmount the filesystem, enter:
<code># umount /mnt </code>

Requisite packages: devices.loopback.rte

====== AIX: Mount ISO Image (before AIX6.1TL4)======

First Create a filesystem with crfs command:
<code>
#/usr/sbin/crfs -v jfs -g rootvg -a size=800 -m/cd1iso -Ano -pro -tno -a frag=4096 -a nbpi=4096 -a ag=8

</code>

This command creates the /cd1iso file system on the rootvg volume group.

Now dd the "iso" image into rlv00
<code># dd if=image.iso of=/dev/rlv00 bs=10M</code>

Use chfs to change the attributes of a file system:
<code>
# chfs -a vfs=cdrom cd1iso
# mount /cd1iso
# cd /cd1iso
</code>

When done, remove the filesystem/unmount, enter:
<code># rmfs /cd1iso </code>

This removes the /cd1iso file system, its entry in the /etc/filesystems (created using chfs command) file, and the underlying logical volume.
