Dell EMC OpenManage Essentials Version 2.5 User's Guide

Discovering a chassis and its components by using Guided Wizard

When you discover a chassis using the Chassis (CMC) Discovery — All Components device type filter within the Guided Wizard, OpenManage Essentials automatically discovers the components in the chassis (blade servers and IOA switches). To discover the chassis and its components, you must provide the hostname or IP address and the WS-Man credentials of the chassis.

By default, the blade servers (iDRACs) in the chassis are discovered using the WS-Man credentials you provide for the chassis. If the credentials of the chassis and the iDRACs are not the same, you can provide an alternate WS-Man credentials for discovering the iDRACs.

  • NOTE: If required, you can use the Guided Wizard to only discover the chassis.
  • NOTE: Automatic discovery of the blade servers in a chassis is supported only for Dell's 11th or later generation of PowerEdge servers (iDRAC 6 or later).
  • NOTE: For discovering a PowerEdge M1000e chassis and its components, ensure that CMC firmware version 5.0 or later is installed. If the firmware installed is prior to version 5.0, you must discover the chassis and its components individually using the Standard Wizard.
  • NOTE: Automatic discovery of IOA switches is supported only if chassis firmware version 5.1 or later is installed on PowerEdge M1000e and chassis firmware version 1.3 or later is installed on PowerEdge FX2/FX2s.
  • NOTE: To discover MX7000 chassis, you must provide the REST credentials. In a Multi-Chassis Management (MCM) group, provide the REST parameters of lead MX7000 chassis.
  • NOTE: During the discovery of MX7000 chassis, if Secure Mode is not selected under REST Configuration Options then OpenManage Essentials ignores the following certificate errors:
    • Common name errors
    • Untrusted certificate authority errors
    • Revocation errors
    However, other certificate errors are not ignored by OpenManage Essentials.
To discover a chassis and its components by using Guided Wizard:
  1. Click Manage > Discovery and Inventory . The Discovery and Inventory Portal wizard is displayed.
  2. Under Common Tasks, click Add Discovery Range. The Discovery Range Configuration page of the Discovery Devices wizard is displayed.
  3. Select the Save as Group option and enter a name for the group.
    • NOTE: When discovering a chassis by using the guided wizard, you must save the discovery range as a group.
  4. Enter the hostname or IP address of the chassis and click Add. In a Multi-Chassis Management (MCM) group, provide the hostname or IP address of lead MX7000 chassis.
  5. Click Next. The Device Type Filtering page is displayed.
  6. Select Chassis (CMC) Discovery - All Components and click Next.
    • NOTE: To discover the MX7000 chassis, you must select MX Chassis Discovery - All Components.
    The ICMP Configuration page is displayed.
  7. If required, change the timeout and retries values based on your preference.
  8. Click Next. If you select MX Chassis Discovery - All Components, the REST Configuration page is displayed.
  9. Select Enable REST discovery and enter the MX7000 chassis credentials.
  10. If required, change the timeout, retries and port values based on your preference, and then click Next. The WS-Man Configuration page is displayed.
  11. Select Enable WS-Man discovery and enter the chassis credentials.
  12. If required, change the timeout, retries, and port values based on your preference, and then click Next.
  13. If you want to disable auto discovery of the chassis components or if you want to enter alternate credentials for discovering the iDRACs, click Alternate WS-Man Configuration for iDRACs .
    • To disable the auto discovery of iDRACs and switches, clear the Auto discover iDRACs and switches in the CMC option.
    • To provide alternate credentials for discovering the iDRACs, clear the Use same credentials of CMC for discovering iDRACs option, and enter the iDRAC username and password.
    • NOTE: If you have selected MX Chassis Discovery - All Components only in the Device Type Filtering page, enter the WS-Man credentials to discover the chassis components.
  14. Click Next. The Summary page is displayed.
  15. Review the protocol configurations and click Finish. A job is initiated to discover the chassis and its components (iDRACs and IOA switches).
