If you are getting an unrecognized file system error message when you mount DVD on the HPUX server. This article gives multile methos to fix the issue and achieve you objective.
Now, we will have a real-life scenario where an Oracle DBA is trying to install Oracle 12c on an HP Integrity Servers with an Itanium processor. hence, These servers are using HPUX as their Operating System.
In this case, He downloaded the Oracle zip files on his Windows workstation; then, extracted them. finally, burned the content on a DVD. not to mention, He uses Windows Operating system on his workstation.
Surprisingly, HPUX did not read the DVD which works on Windows. not to mention, It gives the unrecognized file system error message.
DVD File systems
DVD can have two types of files systems
- UDF file system.
The Universal Disk Format (UDF or ISO/IEC 13346) which is widely used for DVDs. It’s is a recent one too ( release date is late 95 ). HPUX does not support it . therefore, the HPUX gives error when try to mount the DVD.
- ISO 9660 /Joliet
Standard file system for CDs and DVDs which all Operating systems support it.
How to mount DVD in HPUX
Unfortunately, there is no easy workaround. If the DVD file system is not backward compatible. Then, You have to get another one with supported file system.
On the other hand, you could access it over the network as a windows share from HPUX. In order to mount a CD, you have to burn the CD /DVD with ISO9660 file system.
Steps to mount the CD/DVD
Find CD / DVD device name. We can achieve this by executing ioscan command. this will allow you to mount the DVD or CD.

Notice in the “Description” column the DVD title “DV-W28S-VS”. which we gave to the DVD in burning time. hence, we can Identify the device name In the same record /dev/dsk/c1t0d0.
Next, Check DVD has a supported filesystem or not
[email protected]#fstyp -v /dev/dsk/c1t0d0 unknown_fstyp (no matches)
If you get the above error message, It means you need to change the DVD and burn it using the Joliet filesystem.
Finally, create a directory and mount the DVD into it.
[email protected]#mkdir /mnt/cdrom [email protected]#mount -t iso9660 /dev/dsk/c1t0d0 /mnt/cdrom
To sum up, there are three ways to get files into your HPUX server. Download it directly from the internet, mount the DVD, or access it over the network.
