HP Systems Insight Manager 5.2 Update 2 Technical Reference Guide

NOTE: The WBEM providers cannot be installed on HP-UX or Linux systems.
NOTE: A Common Information Model Object Manager (CIMOM) acts as the interface for
communication between WBEM providers and management applications such as HP SIM.
The CMS must have the correct credentials to authenticate to WBEM and WMI. There are two ways
to authenticate HP SIM to a client:
• Basic authentication to WBEM Services or WMI using user name and password.
• Using the CMS certificate to authenticate is available only for HP-UX WBEM Services 02.05.00,
which supports client certificate authentication. Use the Configure or Repair Agents Use an HP
SIM WBEM certificate (good for 10 years) rather than username/password to manage the
system option to deploy a WBEM certificate to the managed system and is only valid for HP-UX
systems.
• WMI An API in the Windows operating system that enables systems in a network, typically enterprise
networks, to be managed and controlled.
The WMI Mapper Proxy is a configuration setting for WMI. The WMI Mapper receives client CIM/XML
WBEM requests and converts the requests to Windows Management Instrumentation (WMI) requests.
The WMI results are converted to CIM/XML format and returned to the Central Management Server
(CMS). The discovery and Identification task uses the proxies in the WMI Mapper Proxy list to discover
whether a system is a WMI-enabled system. If the system is WMI-enabled, then the identification
information for that system based on that specific proxy is returned.
The WMI Mapper makes it possible to retrieve WMI instrumented data on a Windows machine through
WBEM requests. The Windows version of HP SIM installs this WMI Mapper locally so that it can make
WMI requests across the network to the systems without the need to install the WMI Mapper on the
managed Windows systems.
The WMI Mapper is included in a Typical install of HP SIM on a Windows CMS (optional in a Custom
install) . For HP-UX and Linux-based CMS's, the WMI Mapper is not available.
• Simple Network Management Protocol (SNMP) One of the management protocols supported by HP
SIM. Traditional management protocol used extensively by networking systems and most servers.
Management Information Base for Network Management of TCP/IP-based internets (MIB-II) is the
standard information available consistently across all vendors.
If SNMP is not part of the Windows operating system install, you can install it from the Windows CD
as a component. Verify on the target system that the SNMP service allows a remote connection from
the CMS. If there are different read community sets on the target system, ensure that the read community
string is configured in CMS SNMP protocol. To ensure that the Set read community string option in
Configure or Repair Agents is set to public, select Configure→Configure or Repair Agents. Step 4
of Configure or Repair Agents enables you to configure the Set read community string option. See
“Windows CMS” for additional information.
To install the HP Insight SNMP agents for ProLiant systems running on Linux x86 operating system, go
to www.software.hp.com and select the ProLiant Support Pack 7.90.
NOTE: The SNMP agents cannot be installed on HP-UX systems.
To install the SNMP provider from the Manage Communications page, select Quick Repair→Install
Providers and Agents→Install SNMP Agents (HP ProLiant Insight Management Agents) for
Windows.
To configure the write community string on the CMS, select Options→Protocol Settings→System
Protocol Settings from the HP SIM menu. To configure the community string for multiple systems,
select Options→Protocol Settings→Global Protocol Settings and set the write community string.
• Desktop Management Interface (DMI) An industry-standard protocol, primarily used in client
management, established by the Desktop Management Task Force (DMTF). DMI provides an efficient
