    • Discovery and Service Mapping Patterns uses the Alibaba - Storage Volume (LP) pattern to discover storage volumes during horizontal discovery. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Pattern-based discovery and mapping requirements

    Verify the Alibaba Cloud discovery prerequisites section in Alibaba Cloud discovery using patterns.

    Data collected by Discovery during horizontal discovery

    Discovery populates the data in the CMDB when running the Alibaba - Storage Volume (LP) pattern.

    Table 1. Storage Volume [cmdb_ci_storage_volume]
    Field Description
    Name [name] Name of the disk.
    Object ID [object_id] ID of the disk.
    State [state] Status of the disk. Default value is All.

    For example: In_use, Available, or Attaching.
    Size bytes [size_bytes] Disk size in bytes.
    Storage type [storage_type] Type of the disk.

    Possible values are system or data.
    Install Status [install_status] Install status of the disk. Default value is Installed.
    Operational status [operational_status] Operational status of the disk. Default value is Operational.

    CI relationships

    Discovery creates these relationships to support the Alibaba Cloud storage volume discovery.

    CI Relationship CI
    Storage Volume [cmdb_ci_storage_volume] Hosted on::Hosts Alibaba Datacenter [cmdb_ci_alibaba_datacenter]
    Availability Zone [cmdb_ci_availability_zone] Contains::Contained by Storage Volume [cmdb_ci_storage_volume]
    Virtual Machine Instance [cmdb_ci_vm_instance] Uses::Used by Storage Volume [cmdb_ci_storage_volume]
    Key Value [cmdb_key_value] References Storage Volume [cmdb_ci_storage_volume]

    Tag discovery

    The Alibaba - Storage Volume (LP) pattern collects tags and populates them in the Key Value [cmdb_key_value] table.

    Table 2. Key Value [cmdb_key_value]
    Field Description
    Key [key] Tag key.
    Value [value] Tag value.
    Configuration item [configuration_item] References the Storage Volume [cmdb_ci_storage_volume] table.
