Checking prerequisites

In SA, prerequisite checking is automated. This check occurs before upgrade begins and verifies that all necessary packages/patches are installed on your system, as well as verifying certain environmental conditions (diskspace, locales, required directories, and so on). Most checks are advisory, not mandatory. If a prerequisite condition is not met by your system, you will see a warning and can either stop the upgrade to mitigate the problem or continue the upgrade.

If a required package is not installed on any machine that will host a SA Core Component, you must install the package before performing the upgrade.

For more information about required packages, see the SA 10.51 Install section.
