Why Discover NetApp in ServiceNow?

Before we jump into the how, let's talk about the why. Why should you even bother discovering your NetApp filers, volumes, and aggregates in ServiceNow? Here’s the lowdown:

• Visibility: First and foremost, discovery gives you complete visibility into your NetApp storage infrastructure. No more guessing what's out there or relying on outdated spreadsheets. You'll have a real-time, accurate view of all your NetApp assets.
• Configuration Management: With discovery, you can automatically populate your Configuration Management Database (CMDB) in ServiceNow. This means you'll have detailed configuration information for each NetApp component, including models, serial numbers, firmware versions, and more. This is crucial for incident management, change management, and problem management.
• Relationship Mapping: ServiceNow doesn't just show you a list of assets; it maps out the relationships between them. You can see how your NetApp volumes are connected to your servers, applications, and business services. This is invaluable for troubleshooting and impact analysis.
• Compliance: Keeping track of your storage assets is essential for compliance with various regulations and standards. Discovery helps you maintain an audit trail of your NetApp environment, making it easier to demonstrate compliance.
• Automation: Discovery automates the process of asset tracking, reducing the manual effort and potential errors involved in maintaining an accurate inventory. This frees up your IT staff to focus on more strategic initiatives.

Prerequisites for NetApp Discovery

Okay, so you're convinced that NetApp discovery in ServiceNow is a good idea. Great! But before you start clicking buttons, there are a few things you need to have in place:

• ServiceNow Instance: Obviously, you'll need a ServiceNow instance. Make sure you have the Discovery application enabled. This usually comes standard with most ServiceNow subscriptions, but it's worth double-checking.
• MID Server: The MID Server (Management, Instrumentation, and Discovery) is a lightweight application that runs on a server within your network. It acts as a bridge between your ServiceNow instance and your NetApp environment. You'll need at least one MID Server installed and configured.
• NetApp Credentials: You'll need a set of credentials (username and password) that ServiceNow can use to access your NetApp filers. These credentials should have the necessary permissions to query the NetApp API.
• Network Connectivity: Ensure that your MID Server has network connectivity to your NetApp filers. This usually involves opening up the appropriate ports in your firewall.
• NetApp ONTAP API: Make sure that the NetApp ONTAP API is enabled and accessible. This is the API that ServiceNow will use to gather information about your NetApp environment.

With these prerequisites in place, you're ready to start configuring ServiceNow for NetApp discovery.

Configuring ServiceNow for NetApp Discovery

Alright, let's get our hands dirty and configure ServiceNow to discover your NetApp environment. Follow these steps:

1. Install the NetApp Pattern: ServiceNow uses patterns to discover different types of devices and applications. You'll need to install the NetApp pattern from the ServiceNow Store. Simply search for "NetApp" in the store and install the relevant pattern. This pattern contains the logic needed to identify and classify NetApp devices.
2. Create a Discovery Schedule: A discovery schedule tells ServiceNow when to run the discovery process. You can create a schedule that runs daily, weekly, or at any interval you choose. Go to "Discovery" > "Discovery Schedules" and create a new schedule. Configure it to target your NetApp filers.
3. Configure Discovery Credentials: You'll need to provide ServiceNow with the credentials it will use to access your NetApp filers. Go to "Discovery" > "Credentials" and create a new credential record. Select "SSH Credentials" or "SNMP Credentials" depending on your NetApp configuration. Enter the username and password that ServiceNow will use to authenticate.
4. Configure Discovery Probes: Discovery uses probes to gather information about your NetApp devices. You may need to configure the probes to use the correct credentials and ports. Go to "Discovery" > "Probes" and search for the NetApp probes. Verify that they are configured correctly.
5. Test the Discovery: Before you run a full discovery, it's a good idea to test it on a single NetApp filer. This will help you identify any configuration issues before they impact the entire environment. Run the discovery against a single filer and check the results.

Running the Discovery

Now that you've configured ServiceNow, it's time to run the discovery. Here's how:

• Run the Discovery Schedule: If you've created a discovery schedule, ServiceNow will automatically run the discovery at the scheduled time. You can also manually run the schedule by clicking the "Execute Now" button.
• Monitor the Discovery: As the discovery runs, you can monitor its progress in the Discovery Status page. This page shows you which devices are being discovered and whether any errors are occurring. Keep an eye on this page to ensure that the discovery is running smoothly.
• Review the Results: Once the discovery is complete, you can review the results in the CMDB. Go to "Configuration" > "CMDB" and search for your NetApp filers. You should see detailed information about each filer, including its model, serial number, firmware version, and more.

Troubleshooting Common Issues

Of course, no IT project is complete without a few hiccups along the way. Here are some common issues you might encounter during NetApp discovery and how to troubleshoot them:

• Connectivity Issues: If ServiceNow can't connect to your NetApp filers, check your network connectivity and firewall rules. Make sure that the MID Server can reach the NetApp filers on the appropriate ports.
• Authentication Issues: If ServiceNow can't authenticate to your NetApp filers, double-check your credentials. Make sure that the username and password are correct and that the credentials have the necessary permissions.
• Pattern Issues: If the NetApp pattern isn't working correctly, check the ServiceNow logs for errors. You may need to update the pattern or modify it to fit your specific environment.
• MID Server Issues: If the MID Server is having problems, check its logs for errors. Make sure that the MID Server is running and that it has sufficient resources.

Benefits of a Well-Populated CMDB

Once you've successfully discovered your NetApp environment and populated your CMDB, you'll start to see the benefits. A well-populated CMDB can improve your IT operations in several ways:
