Hi,
this is not your unzip or tar or gzip problem.
Your file system not formatted with the largefiles support. thats why the problem comes.
format it with large file support

#newfs -F vxfs -o largefiles /dev/vgash/rlvdata


Thanks & Regards

Are you sure? gzip doesn't support large files. Only Steve's new unzip does.

>format it with large file support
#newfs -F vxfs -o largefiles /dev/vgash/rlvdata

Why would you want to destroy 100s of Gbs of data just to change the type? Just use:
# fsadm -f vxfs -o largefiles device

First, let's leave gzip out of this. It's an
Info-ZIP Zip+UnZip problem. Second, it's not
_my_ new UnZip, I just help a little, here
and there.

Now, who's making these large-file Zip
archives? Info-ZIP Zip 2.x does not support
files (input or output) bigger than 2GB.

Similarly, Info-ZIP UnZip 5.x does not
support files (input or output) bigger than
2GB (no matter who made them).

As previously cited links suggest, you need
Zip 3.x and/or UnZip 6.x to deal with a
large-file Zip archive. The official
releases are not yet available, but the
pre-release ("BETA") source kits (currently
UnZip 6.00d and Zip 3.0g) should be good
enough to do the job.

As usual:

http://www.info-zip.org/
ftp://ftp.info-zip.org/pub/infozip/beta/
http://sourceforge.net/project/showfiles.php?group_id=118012

On the bright side, even the humble (lame)
bundled C compiler on HP-UX should be good
enough to build these programs from the
source kits.

If you have any trouble, be sure to complain.

Thanks for everyone for the advice and good suggestion.
