OpenManage Enterprise 4.1.x User's Guide

Discovering devices

To manage a device using OpenManage Enterprise, perform a device discovery.

By clicking Monitor > Discovery, you can discover devices in your data center environment to manage them, improve their usability, and improve resource availability for your business-critical operations. The Discovery screen displays the number of devices that are discovered in the task and information about the status of discovery job for that device. The job statuses are Queued, Completed, and Stopped. The right pane displays task information such as:

• Total possible devices
• Whether the device is discovered with device types (and their respective count)
• Next run time (for scheduled discovery tasks)
• Last discovered time

View Details in the right pane displays individual discovery job details.

• To perform any tasks on OpenManage Enterprise, you must have necessary role-based user privileges and scope-based operational access to the devices as described in Role and scope-based access.
• In order to support discovery with domain credentials, OpenManage Enterprise (version 3.2 and later) uses the OpenSSH protocol instead of the WSMAN protocol that is used in the previous versions. Hence, all the Windows and Hyper-V devices that are discovered before updating the appliance have to be deleted and rediscovered using their OpenSSH credentials. See the Microsoft documentation to enable OpenSSH on Windows and Hyper-V.
• On the Discovery and Inventory screen, the status of a scheduled job is indicated as Queued in the STATUS column. However, the same status is indicated as Scheduled on the Jobs screen.
• By default, the last discovered IP of a device is used by OpenManage Enterprise for performing all operations. To make any IP change effective, you must rediscover the device.
• For third party devices, you might see duplicate entries if they are discovered using multiple protocols. This duplication can be corrected by deleting the entries and rediscovering the device(s) using only the IPMI protocol.

By using the Discovery feature, you can:

• View, add, and remove devices from the global exclusion list. See Global exclusion of ranges.
• Create, run, edit, delete, and stop the device discovery jobs.
