2GB file size limit

Greetings,
I'm attempting to dump a filesystem from a RHEL5 Linux server to a VXFS filesystem on an HP-UX server. The VXFS filesystem is large file enabled and I've confirmed that I can copy/scp a file >2GB to the filesystem.
Code:
# fsadm -F vxfs /os_dumps
largefiles

# mkfs -F vxfs -m /dev/vg02/os_dumps
mkfs -F vxfs -o ninode=unlimited,bsize=1024,version=4,inosize=256,logsize=16384,largefiles /dev/vg02/os_dumps 2097152000

However, when using the Linux dump utility, it fails 2GB into the dump:
Code:
DUMP: write: File too large
  DUMP: write error 2097170 blocks into volume 1: File too large
  DUMP: Do you want to rewrite this volume?: ("yes" or "no")   DUMP: write: File too large
  DUMP: write: File too large

I've confirmed that I can dump from the same RHEL5 server to another RHEL5 server (ext3 filesystem) without issue so it doesn't seem to be a dump limitation. As I've mentioned, I've also confirmed that can scp a large file (8GB) from the same Linux server to the VXFS filesystem without issue. There seems to be some issue between Linux dump and the HP-UX server/filesystem. This is really starting to drive me nuts. We were previously dumping (via the same script) to a Solaris server without issue. After re-pointing the script to HP-UX, we now now have an issue.

Can someone please shed some light on this? I've tried various dump options and nothing seems to make a difference.

Thanks,
- Bill

NAME
lwp-dump - See what headers and content is returned for a URL SYNOPSIS
lwp-dump [ options ] URL DESCRIPTION
The lwp-dump program will get the resource indentified by the URL and then dump the response object to STDOUT. This will display the headers returned and the initial part of the content, escaped so that it's safe to display even binary content. The escapes syntax used is the same as for Perl's double quoted strings. If there is no content the string "(no content)" is shown in its place. The following options are recognized: --agent str Override the user agent string passed to the server. --keep-client-headers LWP internally generate various "Client-*" headers that are stripped by lwp-dump in order to show the headers exactly as the server provided them. This option will suppress this. --max-length n How much of the content to show. The default is 512. Set this to 0 for unlimited. If the content is longer then the string is chopped at the limit and the string "... (### more bytes not shown)" appended. --method str Use the given method for the request instead of the default "GET". --parse-head By default lwp-dump will not try to initialize headers by looking at the head section of HTML documents. This option enables this. This corresponds to "parse_head" in LWP::UserAgent. --request Also dump the request sent. SEE ALSO
