How to mount an ISO image under Solaris

Mounting an ISO image on Solaris

As 'root' or a user with elevated priviledges perform the following:

  1. Assign a loopback device to the ISO image using lofiadm:
    lofiadm -a <path-to-iso-image>
    For example:
    server# lofiadm -a /var/tmp/sol-10-u8-ga-x86-dvd.iso
    From the above output, we have the lookback device assigned to /dev/lofi/1
  2. Mount the ISO image (loopback device) as a read-only filesystem:
    mount -F hsfs -o ro <loopback-device> <mountpoint>
    For example, to mount /dev/lofi/1 under /mnt:
    server# mount -F hsfs -o ro /dev/lofi/1 /mnt

Presenting ISO images to Guest zones

There is no direct way to mount an ISO image on a Solaris Zone. However, you can mount an ISO image onto the global zone using the above steps, and then present it to the guest zone using:

mount -F lofs <mountpoint> <path-to-zone-root>

For example:

global# mount -F lofs /mnt /zones/guestzone/root/mnt

where: /zones/guestzone/root is the root of the Guest zone. The ISO image should now be visible under /mnt on the Guest zone.

Mounting an ISO image on an already running Guest zone can be useful in scenarios where we need to install sofware from a DVD.

Unmounting the ISO image

  1. To unmount the mounted ISO image:
    umount <mountpoint>
    For example:
    # umount /mnt
  2. Deassign the loopback device from the ISO image:
    lofiadm -d <loopback-device>
    For Example:
    # lofiadm -d /dev/lofi/1
