Ken Zachmann had the most complete way (3 ways) to enable large file support
on Veritas:

Hi Conner,

Since you are using VxFS, there are three ways you can get large
file
support:

1) create filesystems with the support built in:
        mkfs -F vxfs -o largefiles /dev/vx/rdsk/<dg_name>/<vol_name>

2) use the fsadm command to include support for existing file
systems:
        /usr/lib/fs/vxfs/fsadm -o largefiles
/<mount_point_of_your_vxfs>

3) use the mount command (have never done this, but heard it
works):
        mount -F vxfs -o largefiles /dev/vx/dsk/<dg_name>/<vol_name>

There is an option when you create the vxfs to support large
files,
the option is off by default. When you created the file system
you
should have added the "largefiles" option to the mkfs. You
should be
able to use the /usr/lib/fs/vxfs/fsadm tool to set the
largefiles
option on the filesystem (after carefully backing it up ;-)

Vxfs defaults to 2GB max filesize (that format is more widely compatible).
