HP Systems Insight Manager 5.3 Technical Reference Guide

5 Discovery and identification
Discovery is the process of finding systems in the management domain so that they can be managed from
the CMS by HP SIM.
You can perform discovery only if you have administrative rights .
Automatic discovery
The process that HP SIM uses to find and identify systems on your network and populate the database with
that information. A system must first be discovered to collect data and track system health status. The primary
source for automatic discovery is ping sweeps configured in the automatic discovery tasks page. Other
sources might include receiving events from unknown systems or from a management processor that has
information about a server. Identification automatically runs on discovered systems.
The option Automatically discover a system when an event is received from it is disabled by default,
but can be enabled by selecting it in the General Settings for All Discoveries section. For discovery to
run, you must enable the default System Automatic Discovery task by selecting Options→Discovery,
selecting the default task, and then clicking Enable. HP recommends editing this task to ensure that the IP
range is correct.
NOTE: Discovery templates do not exist in HP SIM 5.3 or later. Therefore, after upgrading to HP SIM, 5.3
or later, a disabled discovery task is created for each existing template.
To access the General Settings for All Discoveries section, select Options→Discovery, and then click
Configure general settings. In the section, Do this now to finish the installation, on the introductory
page, click Automatic, or from the Manage section of the Homepage, click discovery.
Alternatively, you can click Edit, instead of Enable, to edit and save the task. In the Schedule section,
select Automatically execute discovery every, and then set the discovery time. If you disable automatic
discovery, no new automatic discovery is performed until you enable automatic discovery by visiting the
Discovery page and making your selections. You can also perform a manual discovery any time that you
choose. See “Configuring automatic discovery” for more information about scheduling automatic discovery.
HP SIM performs automatic discovery using the IP .
Internet Protocol
prodA; discovers systems running IP when it pings systems in a listed range of addresses. It defaults to the
local subnet , a range that corresponds to the IP addresses assigned to the system where HP SIM is running.
You can change the address list to indicate other systems or segments of the network that you want HP SIM
to discover.
Web Agents are not discovered unless HTTP is enabled on the Global Protocol Settings page in the HTTP
settings section. To enable HTTP, see “Setting global protocols” for information. To ensure that clusters are
discovered in automatic discovery, the cluster IP address and all node addresses must be listed in the section,
Ping inclusion ranges, system (hosts) names, templates, and/or hosts files. To access this section,
click New for a new discovery task, or click Edit to edit an existing discovery task.
HP SIM uses a globally unique system identifier obtained from the system to help identify HP systems with
multiple IP addresses. If no unique identifier can be obtained, the fully qualified DNS names of the systems
are used for each IP. To ensure systems are resolved, for each IP address, the FQDN names must match.
Event-based automatic discovery
Event-based automatic discovery is disabled by default. You can enable this feature by selecting
Automatically discover a system when an event is received from it. Event-based automatic discovery
adds any systems that send SNMP traps , WBEM indications, or other events to HP SIM that do not have a
matching IP address in the database. The option, Ping exclusion ranges, templates, and/or hosts files
(in the General Settings for all Discoveries section), allows the entry of any IP addresses that you want
excluded from event-based automatic discovery. If SNMP is disabled on the Global Protocols Settings
page under Options→Protocol Settings→Global Protocol Settings, then SNMP traps are ignored. If
WBEM is disabled, WBEM indications are also ignored.
