Patching AIX from the command-line

Many people use SMIT when updating AIX and/or NIM but do not realise that they can also do this from the command-line using two IBM-supplied sctripts. Patches downloaded from Fix Central should all be in one directory e.g. "6100-08-02-1316".

Change to the directory containing the patches and ensure that it is writeable, so inutoc can create/update the index, all that the files are readable by root.

# cd 6100-08-02-1316
# inutoc .

Run the patch-install script:

# install_all_updates -d . -Y


Pre-installation Failure/Warning Summary
Name                      Level           Pre-installation Failure/Warning
sysmgt.websm.rte         Requisite failure
sysmgt.pconsole.rte         Requisite failure          Requisite failure


 The results will not only be displayed on the screen but stored in "/var/adm/ras/install_all_updates.log".

You now reboot your system to ensure everything is working OK and once satisfied you can commit all the newly applied fixes in order to remove the old copies and save a lot of space in "/usr".

# installp -c ALL
# oslevel -s

If you are using NIM you will also want to update your LPP_SOURCE so that any new clients will be built to the same OS level. Fortunately this can also be done from the command-line:

Note: NIM can only be patched this way to TL (tech-levels) and not SP (Service Packs).

# cd <patch-directory>
# nim_update_all -d . -s 610spot_res -l 610lpp_res -v -u

Your SPOT and LPP_SOURCE should now be at the same level.
