Check your software to see if they meet the minimum version, compiler, and patch requirements for installation:
# uname -a
HP-UX hostname B.11.31 U ia64 4156074294 unlimited-user license
In this example, the version of HP-UX is 11.31 and the processor is Itanium.
# /usr/sbin/swlist -l product | grep -i compiler
# /usr/sbin/swlist -l patch | grep PHSS_42686
Alternatively, to list all installed patches:
# /usr/sbin/swlist -l patch | more
If the website has a recent version of the patch, then download and install that version.
# /usr/sbin/swlist -l bundle |grep QPK
The QPK (Quality Pack) bundles have version numbers of the form B.11.31.0809.326a
(for the September 2008 release), B.11.31.0903.334a
(for the March 2009 release), and so on.
If a required bundle, product, or fileset is not installed, then install it. See your operating system or software documentation for information about installing products.
Note:
There may be more recent versions of the patches listed in the preceding paragraph that are installed on the system. If a listed patch is not installed, then determine if a more recent version is installed before installing the version listed.
