Create a device discovery job

Create a job to discover either server, chassis, storage, or network devices.

1. Click Monitor > Discovery > Create.
2. In the Create Discovery Job dialog box, a default job name is populated. To change it, enter the discovery job name.

   By default, the dialog box enables you to define properties of similar devices at a time.

   • To include more devices or ranges to the current discovery job, click Add. Another set of the following fields is displayed where you can specify the device properties: Type, IP/Hostname/Range, and Settings.
     CAUTION:A maximum of 8,000 devices can be managed by OpenManage Enterprise. Hence, do not specify large networks that have devices more than the maximum number of devices supported by OpenManage Enterprise. It may cause the system to abruptly stop responding.
   • When discovering a large number of devices, avoid creating multiple discovery jobs using individual IP address and instead use IP range of the devices.
   • To discover devices by importing ranges from the .csv file. See Discover multiple devices by .csv import.
   • To exclude certain devices, remove devices from being excluded, or to view the list of devices excluded from being discovered, see Global exclusion of ranges.
3. From the Device Type drop-down menu, to discover:
   • A server, select Server. See Specify a discovery mode for server discovery.
   • A chassis, select CHASSIS. See Specify discovery mode for chassis discovery.
   • A Dell storage device, or network switch, select DELL STORAGE, or NETWORKING SWITCH. See Specify discovery mode for Dell storage discovery.
   • To discover devices by using multiple protocols, select MULTIPLE. See Specify the discovery mode for multiple discovery jobs.
4. In the IP/Hostname/Range box, enter the IP address, host name, or the range of IP address to be discovered or included. For more information about the data you can enter in this field, click the i symbol.
   NOTE:

   • The range size is limited to 16,385 (0x4001).
   • IPv6 and IPv6 CIDR formats too are supported.
5. In the Settings section, enter the username and password of the protocol that is used for discovering the ranges.
6. Click Additional Settings, to select a different protocol, and change the settings.
   NOTE:To reduce the run time of the discovery job, ensure that:

   • Only the required protocols are selected.
   • Separate ranges for specific protocols are created.
   • Timeout values and retries are reduced.

   NOTE: Enabling this setting will enable alerts on the iDRAC (if disabled), and set an alert destination for the OpenManage Enterprise server's IP address. If there are specific alerts that must be enabled, you must configure these on the iDRAC by enabling the appropriate alert filers and SNMP traps. For more information, see the iDRAC User's Guide.
9. Select Set Community String for trap destination from Application Settings. This option is available only for the discovered iDRAC servers and MX7000 chassis.
