    Key Features

    • Pattern Execution: Starting March 2024, execution of the pattern is disabled by default. Users must synchronize the pattern to the MID Server to create a Configuration Item (CI) for FlashArray.
    • API Support: The pattern supports Pure Storage API version 2.17 for retrieving data related to arrays, volumes, and other components.
    • Data Collection: Essential data collected includes storage server details, cluster nodes, volumes, and network adapters, which are populated in the Configuration Management Database (CMDB).
    • Authentication: Basic authentication credentials must be configured to classify FlashArray resources correctly.

    Key Outcomes

    By utilizing the Pure Storage FlashArray discovery pattern, ServiceNow customers can achieve:

    • Improved visibility of storage infrastructure, enhancing operational efficiency.
    • Accurate inventory management through the automatic population of the CMDB with detailed attributes of storage components.
    • Better alignment of storage resources with business processes, supporting effective IT operations management.

    The Discovery and Service Mapping Patterns application uses the Pure Storage Flash Array pattern to find Pure Storage FlashArray on your infrastructure. Discovering some of these resources requires updating the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Note:
    Starting March 2024, the pattern execution is disabled by default. To create a CI for Pure Storage FlashArray, synchronize the pattern to the MID Server.

    Prerequisites

    Verify that the applications are up to date
    • Discovery and Service Mapping Patterns
    • Visibility Content
    Verify the configuration of the credentials

    Configure basic authentication credentials to classify FlashArray. For more information, see basic authentication.

    Verify the permissions to run REST API calls
    The Pure Storage Flash Array pattern supports the API 2.17 version.
    • /api/1.17/auth/apitoken
    • /api/2.17/auth/session
    • /api/2.17/arrays
    • /api/2.17/volumes
    • /api/2.17/volume-groups
    • /api/2.17/host-groups
    • /api/2.17/hardware
    • /api/2.17/dns
    • /api/2.17/ports
    Note:
    The February 2024 Pure Storage pattern version supports only iSCSI protocol discovery.

    Running Discovery

    To run discovery using Patterns, create a discovery schedule that targets the management IP address of the FlashArray storage. For more information, see Running discoveries in your network.

    Data collected by Discovery during horizontal discovery

    Discovery populates the data in the CMDB when running the Pure Storage Flash Array Pattern.
