Dell EMC OpenManage Essentials Version 2.5 User's Guide

Creating a discovery and inventory task

From OpenManage Essentials, click Manage > Discovery and Inventory > Common Tasks > Add Discovery Range. The Discover Devices wizard is displayed. The type of wizard displayed is based on the configuration in Settings > Discovery Settings . See Configuring Discovery Settings .
In Discovery Range Configuration:
1. If you want to create a range group, select Save as Group, and provide the Group Name.
2. Enter the IP address/range or the host name and subnet mask, and then click Add.
  - NOTE: You can add multiple IP addresses, ranges, or host names. You can add multiple host names separated by a comma delimiter. For example, hostname1, hostname2, hostname3, and so on.
3. To import host names and IP addresses, click Import. You can also import host names and IP addresses included as line items in .csv file. Using Microsoft Excel, you can create a .csv file containing host names or IP addresses.
  - NOTE: The discovery range can be exported as a .csv file by right-clicking All Ranges or a given discovery range. The exported .csv file with the host names and IP addresses can be imported in the same or a different OpenManage Essentials instance.
4. Click Next.
If you have selected the Standard Wizard in Discovery Settings — After you have provided at least one IP address, IP range, host name, or a combination thereof, continue to customize the discovery and inventory options or complete the configuration using the default options. Clicking Finish without setting any further configurations immediately runs the discovery and inventory tasks by using the default SNMP and ICMP protocols. It is recommended that you review and revise your protocol configurations prior to clicking Finish. For more information about each listed protocol, click the help icon in the appropriate protocol configuration screen.
- NOTE: When discovering ESXi-based servers, to view the guest virtual machines grouped with the host, enable and configure the WS-Man protocol.
- NOTE: By default, SNMP is enabled and values are assigned ICMP parameters.
- NOTE: ICMP ping is optional for OpenManage Essentials version 2.4 and later. The ICMP parameters are applied depending on the selection of Skip ICMP ping during discovery setting.
- NOTE: After completing any of the following steps, click either Next to continue or click Finish to complete the Discovery Range Configuration.
- In ICMP Configuration, to detect devices on the network, edit the ICMP parameters.
  - NOTE: The ICMP Configuration window is not displayed if Skip ICMP ping during discovery setting is selected under Settings > Discovery Settings.
- In SNMP Configuration, to discover servers, provide the SNMP parameters. You can select SNMP V1/V2c or SNMP V3 for discovery. Ensure that the SNMP community string specified in Get Community matches the SNMP community string of the device or devices you want to discover using SNMP V1/V2c. For discovery and inventory of the devices using SNMP V3, ensure the devices are configured with same username and password, authentication protocol, and encryption protocol credentials, that is used when discovering the devices.
  - NOTE: If the user selects both SNMPv1/v2c and SNMPv3 options, then the discovery of devices using SNMPv3 takes higher priority than discovery of devices using SNMPv1/v2C. The Discovery Range Configuration Details displays the discovery protocol selected for a particular discovery range.
  - NOTE: iDRAC supports only the default SNMP port 161. If the default SNMP port is changed, iDRAC may not get discovered.
- In WMI Configuration, to authenticate and connect to remote devices, provide the WMI parameters. The format for entering credentials for WMI must be domain\user name for domain-based networks or localhost\user name for non-domain based networks.
- In Storage Configuration, to discover PowerVault modular disk array or EMC devices, edit parameters.
- In WS-Man Configuration, to enable discovery of PowerEdge VRTX, iDRAC 6, iDRAC 7, ESXi installed servers, and VxFlex Ready nodes, provide WS-Man parameters.
- In REST Configuration, to enable discovery of MX7000 chassis, provide REST parameters. In a Multi-Chassis Management (MCM) group, provide the REST parameters of lead MX7000 chassis.
- In SSH Configuration, to enable discovery of Linux-based servers, provide SSH parameters.
- In IPMI Configuration, to enable server discovery, provide IPMI parameters. IPMI is typically used to discover BMC or iDRACs on servers. You can include the optional KG key when discovering RAC devices.
- In Discovery Range Action, choose to discover, inventory, or perform both tasks. The default option is to perform both discovery and inventory.
- Select Perform only discovery or Perform both discovery and inventory to run the task immediately.
- To schedule the task to run at a later time, select Do not perform discovery or inventory, and follow the instructions in Scheduling Discovery and Scheduling Inventory.
If you have selected the Guided Wizard option in Discovery Settings — After you have provided at least one IP address, IP range, host name, or a combination thereof, click Next. The Device Type Filtering window is displayed. See Device Type Filtering.
1. Select the device types that you want to discover and manage. The required protocols for discovering the selected devices are added to the Discover Devices wizard.
2. Provide the configuration details for all the protocols listed in the wizard and click Next.
Review your selections in the Summary screen and click Finish. To change any of the parameters in previous configuration screens, click Back. When complete, click Finish.
