AIX 4.3 Installation Tips

APARs mentioned in this document, when available, can be obtained from FixDist. Information on obtaining and using FixDist is available at the following URL:

LED E1DC During Boot on CHRP Systems

     lslpp -L devices.chrp.base.rte

To prevent this problem from occuring, install APAR IX79693, which is included in AIX 4.3.2, and also obtain the latest 4.3.2 diagnostics CD-ROM, P/N 08L1427 or 08L1430. Do not attempt to boot the system with earlier-level diagnostics CD-ROMs or other media that contain a level of AIX prior to 4.3.2.

Once this problem occurs, the only way to correct the condition is to power the system off, unplug the battery for approximately 10 minutes, plug in the battery and power the system back on.

Firmware Corruption Using feprom_update

     1734-009 cannot write in FEPROM

Cannot Run /usr/lpp/diagnostics/da/*platform

WebSM and Microsoft Internet Explorer

This fix is only available in English, and therefore will not resolve the problem for customers who use MSIE 4.01+SP1 in another language.

Once the APAR IX83626 is installed, the customer must reconfigure the web server in applet mode for WebSM. The easiest way to do this is to bring up the Configuration Assistant and complete the task "Configure Web-based System Manager to run in a web browser (applet mode)." This remakes the document links to the modified WebSM files.

Remote Install of bos.rte.SRC Using rsh

• Kill the srcsetsm process using the following commands:

            ps -deaf|grep srcsetsm
            kill -9 process_ID_of_srcsetsm
  

• Reboot the system.

If you want to apply the bos.rte.SRC 4.3.2.0 update using rsh, you can run the rsh in the background. The update will be applied correctly. The rsh will not run to completion, but you will retain control of your login shell.

NOTE: The updated SRC function will not become available until after you have either rebooted or stopped and restarted the SRC daemon (srcmstr). Rebooting is usually preferable since stopping the SRC daemon also stops all its children (which then need to be restarted also).

Known Problems with Parallel Printer Device Driver

• When printing through the AIX Spooler, characters may be repeated after fixing a "paper out" or "printer offline" condition.
• Low speed printers with buffers of 1K or less may see some performance degradation in the print speed.
• Errors logged in the system error log. The label of the error log entries will be "ECP_DMA" or "ECP_INTR".

NOTE: This applies to the ECP parallel port on the planar of 7043 models 150 and 260 only.

Running in Compatibility Mode

/usr/bin/automount is now a script that looks for an environment variable COMPAT_AUTOMOUNT. If COMPAT_AUTOMOUNT is set to any value, the old version of automount is used and it now runs as /usr/sbin/compat_automount.
