Ensure that this account has the necessary permissions to execute commands and retrieve information about the storage environment. Properly configured user permissions are vital for preventing unauthorized access and ensuring the security of your NetApp infrastructure. Always follow the principle of least privilege when assigning permissions to the discovery account.

Finally, verify network connectivity between ServiceNow and your NetApp servers. ServiceNow must be able to communicate with your NetApp devices over the network to perform the discovery. This involves ensuring that there are no firewall rules or network configurations that are blocking communication between the two systems. Test the network connectivity by using tools like ping or traceroute to confirm that ServiceNow can reach your NetApp servers. Additionally, you might need to configure proxy settings in ServiceNow if your NetApp servers are located behind a proxy server. Proper network connectivity is fundamental for a successful NetApp server discovery.

Step-by-Step Guide to Discovering NetApp Servers in ServiceNow

Now that you have the prerequisites in place, let’s walk through the step-by-step process of discovering NetApp servers in ServiceNow. This process involves configuring discovery schedules, setting up credentials, running discovery, and verifying the results. Follow these steps carefully to ensure a successful discovery and accurate population of your CMDB.

1. Configure Discovery Schedules: The first step is to configure discovery schedules in ServiceNow. Discovery schedules define when and how ServiceNow will scan your network for NetApp devices. You can create multiple schedules to target different parts of your NetApp infrastructure at different times. For example, you might have one schedule for discovering NetApp filers and another for discovering storage volumes. When creating a discovery schedule, specify the IP address ranges or individual IP addresses of your NetApp servers. You can also configure the schedule to run automatically on a recurring basis, such as daily or weekly. Regularly scheduled discoveries ensure that your CMDB stays up-to-date with the latest changes in your NetApp environment.

2. Set Up Credentials: Next, you need to set up the credentials that ServiceNow will use to authenticate to your NetApp servers. As mentioned earlier, this typically involves creating a dedicated service account with read-only access. In ServiceNow, you can store these credentials in the Credentials table. When creating a credential record, specify the type of authentication (e.g., SSH, SNMP) and the username and password for the service account. Ensure that the credentials are encrypted and stored securely within ServiceNow. You can also configure credential aliases to simplify the management of credentials across multiple discovery schedules.

3. Run Discovery: With the schedules and credentials configured, you are now ready to run the discovery. You can either wait for the scheduled discovery to run automatically or manually trigger a discovery. To manually trigger a discovery, navigate to the discovery schedule and click the “Run Discovery” button. ServiceNow will then begin scanning your network for NetApp devices using the specified credentials. The discovery process can take some time, depending on the size and complexity of your NetApp infrastructure. Monitor the progress of the discovery in the Discovery Status table to ensure that it is running smoothly.

4. Verify the Results: After the discovery is complete, it is essential to verify the results. Check the CMDB to ensure that your NetApp servers have been discovered and that the relevant information has been populated. Look for configuration items (CIs) representing your NetApp filers, volumes, and aggregates. Verify that the attributes of these CIs, such as IP addresses, serial numbers, and storage capacity, are accurate. If you find any discrepancies, investigate the cause and correct the data in the CMDB. Regularly verifying the discovery results is crucial for maintaining the integrity of your CMDB.
