How is the user trying to create the file? What tools/utilities are in use? What error does the user receive?

Limitation is 2GB file size...I am not mistaken.

Shalom,

If largefiles is enabled the limit after 2 GB is 128 TB.

If I'm not mistaken.

25 GB is not significant.

Check for quotas, its possible to impose them in HP-UX and if not that limitations of the tool the user is using.

Forgot something Jerry.

Check kmtune/kctune output.

There may be a kernel limitation coming to play.

How do you check if largefiles are enabled ?

[NMory]

#fsadm -F vxfs /

To rutn it on:

/usr/sbin/fsadm -F vxfs -o largefiles /dev/vg0#/rlvol#

In order to create large files (> 4G) on HP-UX system, a HFS file system must be enabled to contain large files. That can be accomplished by the following steps:

Unmount the volume.

/usr/sbin/umount

ex: /usr/sbin/umount /newdisk

Configure it to contain large files.

fsadm -F hfs -o largefiles

ex: fsadm -F hfs -o largefiles /dev/vg00/lvol1

Mount it back to be able to create large files.

/usr/sbin/mount -F hfs -o largefiles

ex: /usr/sbin/mount -F hfs -o largefiles /dev/vg00/lvol1 /newdisk

Hope this helps,

Another way

#fstyp -v /dev/vg0#/lvol#

f_flag: 16 = largefiles
f_flag: 0 = no_largefiles
