ServiceNow Discovery uses the NetApp SolidFire storage system discovery pattern to find clusters and nodes on the SolidFire storage system. Discovering some of these resources requires updating the Discovery and Service Mapping Patterns application from the ServiceNow Store.

Request apps on the Store

Visit the ServiceNow Store website to view all the available apps and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the ServiceNow Store version history release notes.

Prerequisites

Discovery and Service Mapping Patterns store app
Verify the Discovery and Service Mapping Patterns store app (version 1.0.74) is installed.
Basic Auth permissions

Ensure Basic Auth credentials are configured for authenticating the Element API calls. Save the following SolidFire Cluster Admin credentials as Basic Auth credentials to ensure proper access:

  • read
  • clusterAdmins
  • reporting
  • drives
MID server
Ensure the MID server can access the target device.
Discovery credentials
Ensure you have the credentials for running Discovery on the host machine running the SolidFire storage system​.
Create a serverless discovery schedule

Create a discovery schedule to perform targeted discovery of SolidFire clusters and nodes.

  1. Navigate to Discovery > Discovery Schedules.
  2. Click New and then fill in the form.
    Table 1. Discovery Schedule form
    FieldDescription
    Name Name for the Discovery schedule. For example, Discover SolidFire.
    Discover Discover type.

    Select Serverless.
    MID Server Name of the MID Server.
    Active Option for enabling this schedule for discovery. Select this check box to enable discovery.
  3. Right-click the header of the Discovery Schedule form and select Save.
  4. Click the Serverless Execution Patterns tab, click New, and then fill in the form.
    Serverless execution pattern
    Table 2. Serverless Execution Pattern form
    FieldDescription
    Name Name for this Serverless Execution Pattern. For example, SolidFire Storage Pattern.
    Pattern Name of the pattern to run: NetApp SolidFire Storage System.
    Proxy Host Fully qualified domain name of the machine on which you are installing the proxy server. Specify Global.
    Active Option for enabling this schedule for discovery. Select this check box to enable discovery.
  5. Under Discovery Pattern Launcher Parameters, configure the launch parameters with the relevant values. Ensure the Management IP of the cluster and Credentials Alias are defined.
