If this command fails to display the contents of the installation media, then enter a command similar to the following to mount it, depending on the platform:
- 
Oracle Linux and Red Hat Enterprise Linux:
# mount -t iso9660 /dev/dvd /mnt/dvd
 
- 
SUSE Linux Enterprise Server:
# mount -t iso9660 /dev/dvd /media/dvd
 
In these examples, /mnt/dvd and /media/dvd are the mount point directories for the installation media.
Note:
Ensure that the 
/mnt/dvd directory exists on Red Hat Enterprise Linux. If it does not, then create the 
/mnt/dvd mount point to mount the installation media.
