Discovery is the process that HP SIM uses to find and identify the systems
on your network and populate the database with that information. A system must first be discovered to collect data and track system status. There are two basic ways to discover new systems: Automatic discovery. The process that HP SIM uses to find and identify the systems on your network to populate the database with that information. A system must first be discovered to collect data and track system status. Manual discovery. The process that enables you to bypass a full automatic discovery and add single and multiple systems to the database, create or import the HP SIM database Hosts file, and create or import a generic Hosts file.
Configuring and executing automatic discovery | |
Select Options Discovery. The Discovery page appears with the Automatic tab selected.
In the For all automatic discoveries section, select Configure general settings. The General Settings section appears.
Select from the following options:
Automatically discover a system when an event is received from it. This option enables systems to be discovered when a trap or some other supported event is received by HP Systems Insight Manager (HP SIM). It uses the discovery filters and IP address exclusion ranges for additional filtering of these events.
Automatically discover a server blade when its Integrated Lights Out management processor is identified. This option adds servers that were indirectly discovered through its management processor. These servers are discovered when its iLO is discovered, they are listed with a Disabled state on the system table view page, and the only information displayed is the system serial number and the association to iLO and the enclosure. If the iLO is in a c-Class enclosure, then the Discover systems in an enclosure when Onboard Administrator is discovered option should also be enabled. Select Discover systems in an enclosure when Onboard Administrator is discovered. This option adds systems known by the Onboard Administrator even if they are not in the configured Discovery range. Select Automatically discover HPVM guest(s) when the host is identified. This option adds all HP Integrity Virtual Machine (HPVM) guest systems to the HP SIM database when the HPVM host system is discovered and identified.
(Optional) In the Ping exclusion ranges, templates and/or hosts files field, specify the IP addresses, templates, or Hosts files containing IP addresses to exclude from the automatic discovery process. This field applies to both range pinging and event-based automatic discovery.
Important: When discovering clusters, the ping inclusion range must include the IP addresses of the cluster and the cluster members. (Optional) Select Enable discovery filters.
In the Discover the following system types: section, select the type of systems to be discovered.
Important: When discovering clusters, you must include the server system type, so that the cluster members are not filtered out.
Note: This option is available only when you select Enable discovery filters.
In the Limit discovery to systems that meet the following criteria section, select from the following:
Any system that matches the above filter
All manageable systems (WBEM, SNMP, DMI, WMI, or HTTP support)
Manageable systems with HP agents only
Note: This option is available only when you select Enable discovery filters.
Click OK to save settings, or click Cancel to close the General Settings section without saving changes.
If you click OK when discovery filters are enabled but have not selected any system types, the following error message appears:
You must make at least one system type selection when enabling filters.
Select System Automatic Discovery. Click one of the following options to schedule it for ongoing operations or to make other changes: Edit, Enable or Run Now. If you would like to create other discovery tasks, click New.
Configuring and executing manual discovery | |
Select OptionsDiscovery, and click the Manual tab. The System Information section appears. Enter the system name or IP address. Click Add System to add the system to the database. If you have not entered the Simple Network Management Protocol (SNMP) or Web-Based Enterprise Management (WBEM) credentials for this system previously, click More Settings. Enter the credentials, then click Add System. Or click More Settings to enter the following information:
Specify additional system properties to use only if Identification fails on this system. Includes:
System type
Click the down arrow and select the appropriate System type.
System subtype
Click the down arrow and select the appropriate System subtype. You can provide up to eight different system subtypes.
Product model
This is a free form field and you can enter the system model number here.
WBEM Settings
Password
If you do not want to use the default global values for the WBEM user name and password, select Use Custom and enter custom values. If you are manually discovering a storage system, ensure that the user name and password of the SMI CIMOM are present in the global protocol settings, or enter them here as custom values. Select OptionsGlobal Protocol SettingsProtocol Settings to view the global settings. For Windows-based systems, the user name should include the domain name, for example, domainname\username. Note: OpenWBEM is not supported.
SNMP Settings
If you do not want to use the default global values for the SNMP settings, select Use Custom, and enter custom values.
Timeout (in seconds)
The amount of time HP SIM waits for an SNMP response when it sends a request to the system. If a response is not received within the time interval, HP SIM might determine that the system does not support SNMP. Decreasing this value can result in increased network traffic because the rate of retry attempts is increased. Use caution when changing this value. A value of three seconds usually works for a LAN. However, If systems are connected through a WAN, try a higher value, for example, 10 seconds.
Retries
The number of additional times after the first attempt is made to communicate with a system before attempts stop.
Read-only community string and Write community string
Note: The Write community string is optional and is only required for firmware updates on a GbE switch. If you need to update the GbE switch firmware, you must first set the write community string from this page and then run the existing switch update task. Do not set this feature if the network is not trusted.
A community string sets up authentication that enables or prohibits communication between the managed system and the Central Management Server (CMS). The community string of the CMS must match the community string of the managed system. Use the read-only community string to read variables. Use the write community string to modify variables. Although only one community is valid for a communication attempt, a system can belong to multiple communities. However, HP SIM only uses one community string when communicating with a system.
