9.7 wipedisk
88 / 193
The product wipedisk overwrites the complete hard disk (partion=0) or several partitions with different patterns. The
number of consecutive write operations to perform is specified as the {product-property iterations (1-25).
10 Inventory
The inventory can be ordered with the Localboot products hwaudit and swaudit or with the Netboot product
hwinvent.
10.1 Hardware Inventory
The hardware inventory is controlled by an opsi configuration file. This means that the information about which data
will be compiled are not hardwired into the corresponding products hwaudit and hwinvent. In fact, the products
will be controlled by a configuration file. The configuration file will be called and interpreted with every dispatch of
the Web service. Simultaneously, the configuration file controls the structure of the database, so that a change of this
configuration file changes the database schema.
The configuration file is /etc/opsi/hwaudit/opsihwaudit.conf.
All the inventoried objects are defined and described in this file, like how these objects and their data are instantiated
(under Linux and Windows). This file will also define the associated data structure. To be more specific, this
configuration file contains the object-oriented inheritance definitions. The reason for this is the fact that a lot of
objects contain identical data fields (i.e. like Name and Vendor). The general information will be defined in virtual
Hardware base classes. The actual inventory objects are then structural Hardware classes, where many properties
could possibly be inherited from overridden virtual base classes.
The following example may be instructive:
At first, the configuration file defines a virtual Class called "BASIC_INFO". This defines the properties (Values):
• "name"
• "description"
Next comes the virtual Class called "HARDWARE_DEVICE", which inherits all the additional parameters from
"BASIC_INFO", and includes the following:
• "vendor"
• "model"
• "serialNumber"
Next follows the first object that is found in the inventory, which is the first structural Class called "COM-
PUTER_SYSTEM", which inherits of all the additional parameters from "HARDWARE_DEVICE", it is defined
(and overwrites properties) as:
• "name"
• "systemType"
• "totalPhysicalMemory"
The class definition will include a description of various parameters and their Values:
