Running Discovery on a Single Device

To refresh discovery for a single device, or force discovery for a single device, perform the following:

In the Device Viewer, click Settings & Status > Management Status > Discover Now. A pop-up dialog appears, displaying the command-line and SNMP directives that NetMRI immediately sends to the selected device. NetMRI executes the processes required against the device to complete discovery. These include SNMP credential collection, SNMP data collection, device group assignment, and CLI credential collection. Scroll through this listing to view specific details on what types of information are being obtained by NetMRI for the selected device. Some time may be required to finish the process.

To force a device to the top of the discovery queue, click Discover Next (below the table).

To remove a device from NetMRI Management, click Unmanage and confirm the operation. Unmanaged devices remain discovered, but the appliance will not collect data from them. NetMRI will not obtain details, (such as vendor, model, and operating system version) because SNMP access is required to complete those processes.

To delete the device from NetMRI's database, perform the following:

1. Click Delete (below the table).
2. In the Delete dialog, select Exclude from discovery (this is optional).
3. If the device has duplicates, you can also select Delete devices instances on other collectors. For more information, see Deduplication of Devices Discovered by Multiple Collectors.
4. Click Yes to confirm the deletion.
