Discovery

The following sections describe how to discover Dell EMC Isilon storage arraysfor monitoring by SL1 using the Dell EMC: Isilon PowerPack.

Discovering Dell EMC Isilon Component Devices

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

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

When the PowerPack is upgraded, some component devices may appear duplicated. You must manually remove existing component devices and then upgrade the PowerPack, or you will need to upgrade the PowerPack and then, manually remove the old components.

To create and run a discovery session that will discover an Dell EMC Isilon appliance:

Go to the Devices page () or the Discovery Session page (Devices > Discovery Sessions) and click the Add Devices button.
Click the Unguided Network Discovery Workflow button. Additional information about that requirements for discovery appears in the General Information pane to the right.

Click Select. The Add Devices page appears.
Complete the following fields:

Discovery Session Name. Type a unique name for this discovery session. This name is displayed in the list of discovery sessions on the Discovery Session tab.
Description.Optional. Type a short description of the discovery session. You can use the test in this description to search for the discovery session on the Discovery Session tab.
Select the organization to add discovered devices to. Select the name of the organization to which you want to add the discovered devices.

Click Next. The Credentials page of the Add Devices wizard appears.
On the Credentials page, locate and select the SOAP/XML credential you created for Dell EMC Isilon appliances.
Click Next. The Discovery Sessionpage of the Add Devices wizard appears.
Complete the following fields:

List of IP/Hostnames. Type the IP address for the TSM appliance.
Which collector will monitor these devices?. Required. Select an existing collector to monitor the discovered devices.
Run after save. Select this option to run this discovery session as soon as you save the session.
Advanced options. Click the down arrow () to complete the following fields:
- Discover Non-SNMP. Enable this setting.
- Model Devices. Enable this setting.
- Select Device Template. If you configured a Dell EMC Isilon device template, select it here. Otherwise, leave the default selection.

If you enabled the Run after save option, click the Save and Run button. The discovery session will run and the Discovery Logs page will display any relevant log messages. If the discovery session locates and adds any devices, the Discovery Logs page will include a link to the Device Investigator page for the discovered device.
If you did not enable the Run after save option, click the Save and Close button. The Discovery Session page (Devices > Discovery Sessions) will display the new discovery session.

To model and monitor your Dell EMC Isilon storage arrays in the SL1 classic user interface, you must run a discovery session to discover the storage arrays that SL1 will use as the root devices for monitoring the Isilon storage system.

To discover the Isilon arrays that you want to monitor in the SL1 classic user interface, perform the following steps:

Go to the Discovery Control Panel page (System > Manage > Classic Discovery or System > Manage > Discovery in the classic user interface).

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

Supply values in the following fields:

IP Address/Hostname Discovery List. Type the IP address or hostname for the Isilon storage array or arrays that you want to discover.

SNMP Credentials. Select the SNMP credential that you created for Isilon devices.
Other Credentials. Select the SOAP/XML credential that you created for Isilon devices.
Discover Non-SNMP. Select this checkbox.
Model Devices. Select this checkbox.
Duplication Protection. Select this checkbox.

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.
Click the Save button to save the discovery session and then close the Discovery Session Editor window.
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.
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:

After discovery has completed, click the device icon for the Isilon Storage Array device ().
From the Device Properties page for the array device, click the Collections tab. The Dynamic Application Collections page appears.

All applicable Dynamic Applications for the storage array 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.

You should see the following Dynamic Applications aligned to the storage array device:

Dynamic Application	Credential Type
Dell EMC: Isilon Cluster Capacity Stats	SOAP/XML
Dell EMC: Isilon Cluster Config	SOAP/XML
Dell EMC: Isilon Cluster Stats	SOAP/XML
Dell EMC: Isilon Cluster Smart Quota	SOAP/XML
Dell EMC: Isilon Node Discovery	SOAP/XML

If the listed Dynamic Applications have not been automatically aligned during discovery, you can align them manually. To do so, perform the following steps:

Click the Actions button and then select Add Dynamic Application. The Dynamic Application Alignment page appears:

In the Dynamic Applications field, select the Dynamic Application you want to align.
In the Credentials field, select the credential specified in the table.
Click the Save button.
Repeat steps 1-4 for the other unaligned Dynamic Applications.

Viewing Dell EMC Isilon 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 Isilon 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 (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 Isilon, find the Isilon 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 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 Isilon 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.
