Additional information for creating STM rules
Manufacturers assign unique system object identifiers to their SNMP instrumented products. In addition,
systems supply information about themselves using variables described in files called Management Information
Bases (MIBs). These values are enumerated using an industry-standard structure. MIBs are provided by
vendors for their systems and must be registered with HP Systems Insight Manager (HP SIM) to be accessible
and usable from System Type Manager (STM). HP preregisters all HP MIBs and many third-party MIBs. You
can register the remaining MIBs using the MIB compiler, if you have the related systems on your network.
See “Registering a MIB” for information on registering MIBs. If you examine a MIB, you will find modules,
or groups of variables. Some variables have multiple values. Each of these values has an object identifier
as well. You can use these object identifiers to determine which system you have and its current behavior
by querying these object identifiers.
Things you should know about DMI identification
DMI identification is based on how a system responds to a DMI request. Systems supply information about
themselves as defined in files called MIFs. MIFs are vendor specific. Simply having a MIF file on a target
system does not guarantee DMI identification. MIFs cannot be registered the way MIBs are registered in HP
SIM. If you examine a MIF (for example, the generic Win32sl.MIF), you will find groups of attributes. The
values returned in response to requests for MIF attributes can be used to determine which system you have
and its current behavior.
For example, the following extract is part of the Win32sl.MIF. Notice the group named Component ID ,
followed by several attributes that identify one aspect of a DMI system, such as Manufacturer, Product,
Version, and Serial Number. Other MIFs have different groups and specify other aspects of a system. The
information in the MIFs is the information you supply to STM when you create a rule. STM can request a
value from a specific target for a specific attribute.
NOTE: DMI identification is only supported on Windows and HP-UX-based Central Management Server
(CMS) installs. In addition, only like operating systems can be identified. For example, Windows-based
CMSs can identify Windows-based DMI, and HP-UX-based Central Management Servers can only identify
HP-UX-based DMI systems.
