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 for All Discoveries 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. This option is not selected by default.
Automatically discover a server blade when its Integrated Lights Out management processor is identified. This option adds servers indirectly discovered through the server's management processor, which are discovered when the server's iLO is discovered. The discovered servers are identified as Disabled on the system table view page. 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, the option ,Discover systems in an enclosure when Onboard Administrator is discovered should also be enabled. Select Discover systems in an enclosure when Onboard Administrator is discovered. This option adds systems identified by the Onboard Administrator even if the systems are not in the configured discovery range. This option is selected by default. Select Automatically discover VM 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. This option is selected by default.
Note: For automatic identification of virtual machine guests running on a virtual machine host, the IP address of the guest is required. To acquire the IP address from Web-Based Enterprise Management (WBEM) Providers, VMWare tools must be installed on the virtual machine guests.
Automatically discover other virtual partitions within the same vPar Monitor when one of the virtual partitions is identified. This option is selected by default.
Automatically discover all nPars within the same complex when one of the nPars is identified. This option is selected by default.
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. You can also enter Simple or Fully Qualified Domain Names (FQDN) host names. However, you cannot enter a range of host names. 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. Select Enable discovery filters.
In the section, Discover the following system types, 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: The option, Limit discovery to systems which meet the following criteria is available only when you select Enable discovery filters. To save settings, click OK, or to close the General Settings for All Discoveries section without saving changes, click Cancel.
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 then click the Manual tab. The System Information section appears. Enter the system name or IP address. Simple or Fully Qualified Domain Name (FQDN) host names can be entered. However, ranges of host names are not allowed. Click Add System to add the system to the database. If you have not entered the 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 Settingsand 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 input up to eight different system subtypes. Product model. Enter the system model number here. This field is free form.
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 then 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. To view the global settings, select OptionsGlobal Protocol SettingsProtocol 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 this time interval, HP SIM might determine that the system does not support SNMP. Decreasing this value can case 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 the attempts stop. Read-only community string and Write community string.
Note: The Write community string is optional and is required only for firmware updates on a GbE switch. If you must 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.
