Using UDF DVD on AIX 5.3
I was trying to copy a 2.5GB mksysb onto a 5.3 lpar to add as a NIM resource. The DVD mounted fine but I could not see any files within the mount point. I thought the media was bad so I tried again with a DVD-R disk but the same thing happened.

I decided to split the file up into 1024MB chunks and burn onto an ISO. This worked fine so the problem must be with the UDF format.

Has anyone successfully written a >2GB file to DVD in UDF format. I suspect there may be a patch for this but I'm not sure where to look.

Thanks,

dvdfs(4)						     Kernel Interfaces Manual							  dvdfs(4)

NAME

       dvdfs - The Digital Versatile Disk File System  [This feature is not supported in Tru64 UNIX Version 5.0]

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       ISO/ITEC 13346:1995

	      Optical Storage Technology Association (OSTA) Universal Disk Format (UDF) Specification, "OSTA UDF Compliant Domain", Version 2.00.

       ISO 9660:1988

	      Information Processing-Volume and file structure of CD-ROM for information interchange.

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

DESCRIPTION

       The Digital Versatile Disk File System enables the reading of disks formatted in the Universal Disk Format (UDF).

       User  data sectors in a DVD-ROM can contain any type of data in any format.  However, for Tru64 UNIX support through the dvdfs file system,
       the OSTA UDF file format standard is mandatory.	The file system limit for DVDFS is int cfs_cdfs_mount_limit = 512.

       Additionally, DVD-ROM standards require that the logical sector size and the logical block (the user data block) size be 2048 bytes.

       DVD support in the UDF specification includes these levels: DVD-ROM (Read-only):

	      Supports reading of UDF-formated files from DVD-ROM disks.  DVD-R (Write-once):

	      Supports the reading of UDF-formated files from a DVD-ROM disk and supports writing, one time, UDF-formated  files  onto	a  DVD-ROM
	      disk.  DVD-RAM (Rewritable):

	      Supports reading and writing of UDF-formated files from and to a DVD-ROM disk.

       At this time, the Tru64 UNIX dvdfs file system supports only the DVD-ROM (Read-only) format.

       See  mount(8) for information about mounting and unmounting a dvdfs file system, fstab(4) for information about including dvdfs file system
       in a system's /etc/fstab file, and disklabel(8) for information about labeling DVD-ROM disks.
