OpenManage Enterprise 4.0.x User's Guide

Create a custom discovery job for servers

Use the Additional Settings dialog box to enter the details for the protocol with which you want to discover servers. The appropriate protocols are automatically pre-selected based on your initial inputs.

1. To Discover using WS-Man/Redfish (iDRAC, Server, and/or Chassis):
   1. In the Credentials section, enter a User Name and Password.
   2. In the Connection Settings section:
      • Retries field, enter the number of repeated attempts that must be made to discover a server. The default value is 3.
      • Connection Timeout field, enter the time after which a job must stop running. The default value is 60 seconds.
      • To check the WS-MAN response from a target before establishing a connection, set the WS-MAN Service Check Timeout. By default the value is set to 1 second with a hardcoded number of retries. If a target iDRAC is slow to respond or there are network delays, it is recommended to increase the timeout value higher than the default to avoid connection failures. The console will generate CDEV6131 alerts in the event of a device connection failure.
      • Change the Port number. By default, 443 is used to connect to the device.

        For supported port numbers, see Management ports and protocols

      • Select the Enable Common Name (CN) check box if the common name of the device is the same as the hostname used to access the OpenManage Enterprise.
      • Select the Enable Certificate Authority (CA) check box, if needed.

      NOTE:

      • If you disable the protocol on a device after its discovery or enable a different protocol on a device post-discovery, the device must be re-discovered with valid credentials. This ensures the correct protocol is used for all operations. This applies to both enabling and disabling protocols post-discovery.
      • For in-band device discovery to be successful, ensure that the firewall on the target server allows Echo Request - ICMPv4-In and Echo Request - ICMPv6-In under Windows Firewall with Advanced Security > File and Printer Sharing.
      • When a certificate is used to discover a device and CA entries are used, the DNS name is used to identify the device and not the IP.
2. To Discover Non Dell devices (OOB) via Redfish:
   1. Select HP iLO or Lenovo XClarity to discover and monitor servers.
   2. In the Credentials section, enter a User Name and Password.
3. To Discover using IPMI (non-Dell via OOB):
   1. In the Credentials section, enter a User Name and Password.
   2. In the Connection Settings section:
      • In the Retries field:
        • In the Retries field, enter the number of repeated attempts that must be made to discover a server.
        • In the Timeout field, enter the time after which a job must stop running.
        • Enter in the Port field to edit the port number. By default, 443 is used to connect to the device.

          For supported port numbers, see Management ports and protocols

        • Select the Enable Common Name (CN) check box if the common name of the device is the same as the hostname used to access the OpenManage Enterprise.
        • Select the Enable Certificate Authority (CA) check box, if needed.
      • In the Timeout field, enter the time after which a job must stop running.
      • In the KgKey field, enter an appropriate value.
4. To Discover using SSH (Linux, Windows, Hyper-V):
   NOTE:Only OpenSSH on Windows and Hyper-V is supported. Cygwin SSH is not supported.
   1. In the Credentials section, enter User Name and Password.
   2. In the Connection Settings section:
      • In the Retries field, enter the number of repeated attempts that must be made to discover a server.
      • In the Timeout field, enter the time after which a job must stop running.
      • Change the Port number. By default, 22 is used to connect to the device.

        For supported port numbers, see Management ports and protocols

      • Select the Verify the known Host key check box to validate the host against known host keys.
        NOTE:Known host keys are added via the /DeviceService/HostKeys REST API service. Please see the OpenManage Enterprise RESTful API Guide for more information about how to manage host keys.
      • Select the Use SUDO Option check box if sudo accounts are preferred.
        NOTE:For sudo accounts to work, the server(s) /etc/sudoer file must be configured to use NOPASSWD.
5. To Discover using ESXi (VMware):
   1. In the Credentials section, enter a User Name and Password.
   2. In the Connection Settings section:
      • In the Retries field, enter the number of repeated attempts that must be made to discover a server.
      • In the Timeout field, enter the time after which a job must stop running.
      • Change the Port number. By default, 443 is used to connect to the device.

        For supported port numbers, see Management ports and protocols

      • Select the Enable Common Name (CN) check box if the common name of the device is the same as the hostname used to access OpenManage Enterprise.
      • Select the Enable Certificate Authority (CA) check box, if needed.
