names to identify products and components and determine which type of
configuration file to use.

Platform Description
Windows The amount of free disk space, with the
following optional qualification
attributes:
v dir attribute, to determine which
path to the directory to check
v unit attribute, to determine which
units for disk space to use
It is the variable to represent a product code on either Windows or UNIX
systems. Product codes identify the product, an individual platform such
as Windows, AIX, HP-UX, Linux, and Solaris, and optionally the version of
the operating system that is supported by that product. They are stored in
the codename.cfg file. Any product that supports multiple platforms has
multiple product codes, with each one identifying a product, platform, and
version of the operating system as required.
For example, the COD, COK and COX product codes identify some of the
supported operating systems and versions for IBM Tivoli Provisioning
Manager:
COD=Tivoli Provisioning Manager for AIX 6.1
COK=Tivoli Provisioning Manager for HP-UX
COX=Tivoli Provisioning Manager for Windows 2008
When you run the Prerequisite Scanner, you pass the product code and
optionally the product version as input parameters. The Scanner
automatically detects the operating system of the machine. It then checks
the operating system against the operating system listed for that product
code in the codename.cfg file.
If the operating system of the machine is supported, the Scanner then uses
the input parameters to find the configuration file in the
ips_root/Windows|UNIX_Linux directory. The file name contains the same
product code and product version as the input parameters. If you do not
pass the optional product version parameter, the Scanner uses the latest
version of the configuration file that it finds in this directory. Prerequisite
Scanner then begins the scan.
Important: If the platform is not supported, Prerequisite Scanner exits and
displays a message to state that the platform is not supported.
