Displaying currently installed AIX filesets

You can verify if the prerequisite filesets are already installed on the AIX system by using the AIX lslpp command. For example, you can check the Mail Handler fileset by entering this at the command line:

lslpp -l bos.mh

If the fileset is installed, AIX displays the level, state, and description of the fileset. If the fileset is not installed, AIX issues an error message. For missing filesets, use the AIX system management interface tool (SMIT) to install the appropriate filesets from the AIX DVD-ROM.
