Patch Name:  PHCO_2463

Patch Description: mv loses a file when writing to a full NFS-mounted disk.

When using mv to move a file to a NFS mounted file system, write failures
because the disk is full are not detected.  This causes the original file
to be lost without any warning to the user.  This problem does not occur
on full local or diskless file system.  The cause of the problem is that
write(2) returns successfully, even thought the NFS mounte file system is
full.  The solution involves checking the return value from close(2), to
see if the data was written successfully.  If close(2) fails, the original
file is not removed.

---------------------------------------------------------------------------
After getting the patch onto your machine, unshar the patch (sh PHCO_2463).

To install this patch do the following:
1) Run /etc/update (Note: you must be logged in as root to update
   a system).
2) Once in the update "Main Menu" move the highlighted line to "Change
   Source or Destination ->" and press "Return" or "Select Item".
3) Make sure the highlighted item in the "Change Source or Destination"
   window is "From Tape Device to Local System ...", then press "Return" or
   "Select Item".
4) You should now be in the "From Tape Device to Local System" window.
   Change the "Source:  /dev/rmt/0m" to "Source: /tmp/PHCO_2463.updt"
   (this assumes that you are in the /tmp directory where PHCO_2463.updt
   has been placed).  Note: You must enter the complete path name.
5) Press "Done".
6) From here on follow the standard directions for update.

The customized script that update runs will move the original software
to /system/PHCO_2463/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended that
you move the PHCO_2463.text file to /system/PHCO_2463 to be retained for
future reference.

If you wish to put this patch on a magnetic tape and update from the tape
drive, dd a copy of the patch to the tape drive.  As an example the
following will create a copy of the patch that update can read:
dd if=PHCO_2463.updt of=/dev/rmt/0m bs=2048
