The following sections describe how to discover Dell EMC Unity storage arrays for monitoring by SL1 using the Dell EMC: Unity PowerPack.

Discovering Dell EMC Unity Component Devices

To model and monitor your Dell EMC Unity storage arrays, you must run a discovery session to discover the Unisphere that SL1 will use as the root device for monitoring the Unity storage system.

After the discovery session completes, the Dynamic Applications in the Dell EMC: Unity PowerPack automatically align to the storage array device, and then the PowerPack discovers, models, and monitors the remaining Unity component devices.

To discover the Unity arrays that you want to monitor, perform the following steps:

  1. Go to the Discovery Control Panel page (System > Manage > Classic Discovery).

  1. On the Discovery Control Panel, click the Create button. The Discovery Session Editor page appears:

  1. Complete the following fields:
  • IP Address/Hostname Discovery List. Type the IP address for the Unisphere.

  • Other Credentials. Select the SOAP/XML credential that you created for Unity devices.
  • Discover Non-SNMP. Select this checkbox.
  • Model Devices. Select this checkbox.
  1. Optionally, you can enter values in the other fields on this page. For more information about the other fields on this page, see the Discovery & Credentials section.
  2. Click the Save button to save the discovery session and then close the Discovery Session Editor window.
  3. The discovery session you created appears at the top of the Discovery Control Panel page. Click its lightning-bolt icon () to run the discovery session.
  4. The Discovery Session window appears. After the devices are discovered, click the device icon () to view the Device Properties page for each device.

Verifying Discovery and Dynamic Application Alignment

To verify that SL1 has automatically aligned the correct Dynamic Applications during discovery:

  1. After discovery has completed, click the device icon for the root device ().
  2. From the Device Properties page for the array device, click the Collections tab. The Dynamic Application Collections page appears.
  1. All applicable Dynamic Applications for the device are automatically aligned during discovery.

It can take several minutes after the discovery session has completed for Dynamic Applications to appear in the Dynamic Application Collections page.

The "Dell EMC: Unity Array Discovery" and "Dell EMC: Unity Components Config" Dynamic Applications are automatically aligned to the root device, after which the rest of the Dynamic Applications in the PowerPack will be aligned.

Viewing Dell EMC Unity Component Devices

In addition to the Device Manager page (Devices > Classic Devices, or Registry > Devices > Device Manager in the classic SL1 user interface), you can view the Unity storage devices in the following places in the user interface:

  • The Device View modal page (click the bar-graph icon [] for a device, then click the Topology tab) displays a map of a particular device and all of the devices with which it has parent-child relationships. Double-clicking any of the devices listed reloads the page to make the selected device the primary device:

  • The Device Components page (Registry > Devices > Device Components) displays a list of all root devices and component devices discovered by SL1 in an indented view, so you can easily view the hierarchy and relationships between child devices, parent devices, and root devices. To view the component devices associated with Dell EMC Unity, find the Unity component device and click its plus icon (+):

  • The Component Map page (Classic Maps > Device Maps > Components) allows you to view devices by root node and view the relationships between root nodes, parent components, and child components in a map. This makes it easy to visualize and manage root nodes and their components. SL1 automatically updates the Component Map page as new component devices are discovered. The platform also updates each map with the latest status and event information. To view the map for an Dell EMC Unity arrays, go to the Component Map page and select the map from the list in the left NavBar. To learn more about the Component Map page, see the section on Views.
