APAR IY09941 on 4.3.2

  ------------------------------------------------------------------------

Description
-----------
This directory contains a fix for APAR IY09941 specially built to be
installed on AIX 4.3.2 systems.

WARNING: This update is not offically part of the service stream for AIX
4.3. AIX is supported on a version and release basis. The AIX maintenance
strategy does not allow maintenance levels within a version and release of
AIX to be supported separately. For example, AIX 4.2 is supported separately
from AIX 4.3, but AIX 4.3.2 cannot be supported separately from AIX 4.3.3.
The reason for this is that he AIX installation architecture assumes that
every fileset update includes all fixes in previous updates to the same
fileset. The official fix for APAR IY09941 was first released in the
4.3.3.15 levels of the bos.mp and bos.up filesets. This special 4.3.2 fix
consists of the 4.3.2.17 levels of bos.mp and bos.up. If any level of bos.mp
or bos.up between 4.3.2.17 and 4.3.3.15 is installed after this special
4.3.2 fix is installed, the fix for APAR IY09941 will be removed even though
the 'instfix' command will still indicate it is installed.

For this reason, this special 4.3.2 fix for APAR IY09941 is not being made
available through the normal IBM fix distribution channels. It is only being
provided at this FTP site as an emergency fix for those customers that do
not feel that they can immediately install the official fix for IY09941.

IBM recommends that rather than installing this special 4.3.2 fix, that you
update your system to AIX 4.3.3, and then install the fix for IY09941
available from the AIX Fix Distribution Service at the following URL.

     http://techsupport.services.ibm.com/rs6k/fixes.html

It is not necessary that you first update your AIX 4.3 system to the 4.3.3
maintenance level before installing the official fix for APAR IY09941.
However, updating to the 4.3.3 maintenance level is recommended, since it
bas been extensively tested as a unit.

Installing just the official fix for APAR IY09941 without first updating to
the 4.3.3 maintenance level will not update your AIX 4.3 system to the 4.3.3
level. The 'oslevel' command will still indicate the previous maintenance
level, although some filesets will be updated to the 4.3.3.x level.


Downloading
-----------
Download the IY09941_432.tar file in binary format into an empty directory.
To extract the file, use the following commands, where 'directory' is the
directory into which the IY09941_432.tar file was downloaded.

     cd directory
     tar -xvf IY09941_432.tar


Requisites
----------
In order to ensure that all necessary requisite updates for this package are
installed, the level of your installed kernel must be at the 4.3.2.10 or
later level. To check the level of your kernel, use the command:

     lslpp -L "bos.[mu]p"

Systems would normally only have either the bos.mp (multiprocessor kernel)
or bos.up (uniprocessor kernel) fileset installed. If your kernel is below
the 4.3.2.10 level, you must obtain the 4.3.2.10 level from the AIX Fix
Distribution Service at the following URL. The update images should be
downloaded into the directory into which you downloaded IY09941_432.tar
file.
