Discovery in HP SIM
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 Configure discovery and credentials, 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. For more information about scheduling
automatic discovery, see Configuring automatic discovery.
HP SIM performs automatic discovery using the IP.
Internet Protocol
HP SIM 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 Protocol settings 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, 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 SNMPtraps, WBEM indications, or other events to HP SIM that do not
have a matching IP address in the database. The option, Ping exclusion ranges, and/or hosts files
