Updating installed software from the command line

Edit online

The install_all_updates command updates installed system software to the latest level that is on the media, and verifies the current recommended technology level.

Beginning in AIX 5L Version 5.2 with the 5200-01 Recommended Maintenance package, if you select the option to install all devices and kernels during a BOS installation, then during subsequent update_all processing, any new devices.* filesets are installed from the installation media. This option can be turned off by setting the ALL_DEVICES_KERNELS variable in the /var/adm/ras/bosinst.data file to no.

If the ALL_DEVICES_KERNELS variable is set to no, the install_all_updates command does not install any filesets that are present on the installation media but not installed on the system, unless these filesets are installed as requisites of other selected filesets.

For installp images, all installp requisites are enforced.

The following example shows how to install all installp updates on the /dev/cd0 device and to verify the current recommended technology level:

# install_all_updates -d /dev/cd0
