## Adding a Device

After the initial discovery, you can use **'Add Storage Device'** option under **Settings → Discovery** to add a new device.

| Note: Only Admin users can add devices. |
|---|

**Steps for adding a Device :**

- Click the ‘Settings’ tab in the OpManager client.
- Select ‘Discovery' tab and click on 'Add Storage Device'.
- Enter the IP address of the new device.
- Choose the Device Type whether it is a RAID array, FC Switch or a Tape Library.
- Choose the Device model of the storage device.
- Depending on the Device model selected, enter the credential as SNMP/SMI/CLI/NetAppAPI/Storage API.

| Note: If you want to add a new credential, click the **'Add Storage Credential'** button on the top right corner and provide the necessary details. |
|---|

- You can test the device right away from the same window by clicking the 'Test Connection' button.
- Click 'Add Device' button to add it.

## Adding Device Details

Clicking on any device name in the Inventory tab takes you to the device snapshot page. There you can view all the operational stats of the device in a single pane and also its basic details such as IP Address, Device vendor and model, Firmware version, and so on.

**To edit the device details**

1. Go to the **Inventory** tab, click on ‘Storage’ and then click on the device whose details you want to edit.
2. In the device snapshot page that is opened, click on the **three-line menu button** on the top-right corner of the screen and select **‘Edit Device Details’**.
3. Here, you can change the details of the device namely **IP Address, Display name** and the **monitoring interval**.

| Note: Only Admin users can add and edit device details. |
