Patch Name:  PHKL_2809

Patch Description: Set nfs client block transfer size to 8K block size

This change is identical to the sun nfs v4.2 code which unconditionally
sets the nfs client block transfer size to 8kb. This was in response
to HP clients using smaller block size (4k) when it was not necessary.
This in turn resulted in slower performance throughput on the nfs filesystem.

---------------------------------------------------------------------------
After getting the patch onto your machine, unshar the patch (sh PHKL_2809).

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/PHKL_2809.updt"
   (this assumes that you are in the /tmp directory where PHKL_2809.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/PHKL_2809/orig.  HP recommends keeping this software there in
order to recover from any potential problems.  It is also recommended that
you move the PHKL_2809.text file to /system/PHKL_2809 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=PHKL_2809.updt of=/dev/rmt/0m bs=2048
