NetApp Server and Cluster discovery

  • Release version: Washingtondc
  • Updated February 1, 2024
  • 4 minutes to read

    • Discovery and Service Mapping find NetApp servers and clusters using either CIM probes or patterns. Discovering some of these resources requires updating the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Request new or enhanced Patterns on the ServiceNow® Store

    Visit the ServiceNow Store to view all the available updates 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.

    NetApp discovery is not supported for NetApp servers in the AWS cloud. To learn about the components and versions of NetApp servers and clusters that you can discover, refer to Detailed information on products discovered by ITOM Visibility.

    NetApp Server and Cluster discovery methods

    Method Supported modes Upgrades
    Discovery with patterns using ONTAP API.

    These patterns support native discovery of NetApp servers without requiring the discovery of the SMI-S server.
    • NetApp 7-mode
    • NetApp cluster mode

    Active by default.
    Discovery with patterns using HTTP REST API. NetApp cluster mode

    Available on Discovery and Service Mapping Patterns store application starting August 2023.
    Discovery with probes and sensors using SMI-S.
    • NetApp 7-mode
    • NetApp cluster mode

    Legacy
    Note:
    This is not applicable for cloud-supported NetApp servers.

    NetApp discovery properties

    To use discovery with patterns, navigate to Discovery Definition > Properties and enable these properties:
    Property label Name
    For 7-Mode NetApp storage servers use native discovery instead of SMI-S. glide.discovery.sensors.netapp_native_7mode
    For Cluster Mode NetApp storage servers use native discovery instead of SMI-S. glide.discovery.sensors.netapp_native_cluster_mode
    Note:
    If you have already performed NetApp discovery with Probes and then enable these properties, a migration script runs the next time you perform NetApp discovery. This script could delete CIs for items like storage pools, which probes discover but the patterns do not. It also creates relationships.

    Prerequisites

    General prerequisites
    Verify the applications are up to date:
    • Discovery and Service Mapping Patterns
    • Visibility Content
    Disable SSLv3 and enable TLS for the target NetApp server, as the Java Runtime used by the MID Server does not enable SSLv3 by default. The key to encrypt the certificate must be at least 1024 bits.
    SNMP-based discovery prerequisites
    Configure SNMP community credentials to classify the NetApp server. For more information, see SNMP community credentials.
    Enable read-only access to the ONTAP API on the NetApp server.
    • Cluster mode: the user can have a read-only role with default access.
    • 7-mode: the user must have a custom role with the following capabilities:
      • login-snmp, login-ndmp, login-sp, and login-http-admin
      • Api-*
    Configure basic authentication credentials for the read-only user. For more information, see Basic authentication credentials.
    REST-based discovery prerequisites:
    Disable SNMP-based discovery. For more information, see Disable SNMP-based NetApp storage cluster discovery.
    Verify the application user has a read-only role.
    Configure basic authentication credentials for the read-only user. For more information, see Basic authentication credentials.

    Running Discovery

    To run discovery using Patterns, create a discovery schedule that targets the management IP address of the NetApp server.

    Note:
    NetApp creates different storage volume identifiers when running with different protocols. When running discovery with HTTP after running discovery with SNMP, duplicate CIs are created for the same storage volume. One CI is created for the unique identifier (UUID) NetApp ONTAP API provides, and one CI is created for the unique identifier (UUID) NetApp HTTP REST API provides.
