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: Discovering groups of systems The process that HP SIM uses to find and identify the group of systems on your network to poplulate the database with that information. A system must first be discovered to collect data and track system status. You can also discover systems using host file. Discovering a single system The process that enables you to discover and add systems to the database.
Configuring and executing automatic discovery | |
Select Options Discovery. The Discovery page appears.
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 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 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 must be enabled. 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. Automatically discover VM guest(s) when the host is identified. This option adds all VM guest systems to the HP SIM database when the a VM host (HPVM VMWare ESX or Microsoft Hyper-V) system is discovered and identified. This option is selected by default. If this option is not selected when a VMWare ESX or Microsoft Hyper-V host is discovered, then guests are not discovered automatically. However, if one of its guests is moved to another before being discovered in HP SIM and if that guest is discovered later, it is associated with the old host. To avoid this, either the old host or new host must be identified before guest is discovered
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 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 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. To select the types of systems HP SIM discovers, 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, View Task Results, or Run Now. If you would like to create other discovery tasks, click New.
Configuring a discovery task | |
To configure and execute a discovery, you must create a Discovery task. HP SIM ships includes one default discovery task (System Automatic Discovery). However, you can create a new discovery task to discover specific systems. For example, if you want to discover systems in a specific IP address range. You can set the task to run at scheduled times using specific ping inclusion ranges, templates, or hosts files. To create a discovery task: Select OptionsDiscovery. The Discovery page appears with the Automatic tab selected. To create a new discovery task, click New. The New Discovery section appears. Select from the following:
Discover a group of systems (Default) Select this option to discover more than one system. (Required) In the Name field, enter a name for the task. In the Schedule section, select Automatically execute discovery every, and then enter how often the task runs. The default frequency is once per day. If you clear the Automatically execute discovery every option, the task is disabled after you create it. In the Ping inclusion ranges, system (hosts) names, templates, and/or hosts files field, specify the IP addresses. If you want to use this task to discover SMI-S storage systems, include the IP address of each SMI CIMOM. You can also enter Simple or FQDN host names. However, you cannot enter a range of host names. To use an existing hosts file, enter the hosts file name in the following format:
$HostsFileName
. If a hosts file is used, only systems that are accessible and match the discovery filter criteria are added to the database.
Enter comments in the Comments field. Comments entered here are displayed in the discovery table on the Discovery page.
Discover a single system Select this option to discover one system. Single system discovery address the system to the HP SIM database regardless of network reachability, unless it is not DNS resolvable. (Required) In the Name field, enter a name for the task. In the Schedule section, select Automatically execute discovery every, and then enter how often the task runs. The default frequency is once per day. If you clear the Automatically execute discovery every option, the task is disabled after you create it.
Enter the system name or IP address in the Enter the system's name or IP address.
Enter comments in the Comments field. Comments entered here are displayed in the discovery table on the Discovery page.
To set system credentials, click Credentials.
To create an associated Configure or Repair Agents task, click Configure/Repair.
To configure system types, click System Types.
| | | |  | NOTE: System Types is only available when you discover a single system. | | | | |
To save the task, click Save, to run the task immediately, click Run Now, or to close the New Discovery section and not save any settings, click Cancel.
Note: If you have selected many systems, the following message appears, stating The automatic discovery task is configured with a large number of addresses: [NUM]. Click OK to continue, or click Cancel to change the IP address range.
