    Summary of Cisco Unified Computing System (UCS)-HD device discovery

    The Cisco Unified Computing System (UCS)-HD device discovery enables ServiceNow Discovery and Service Mapping Patterns to identify and map Cisco UCS equipment such as chassis and blades within your IT environment. This discovery focuses specifically on B-series UCS devices and populates detailed configuration items (CIs) in the ServiceNow CMDB.

    To use this functionality effectively, it is important to have the latest Discovery and Service Mapping Patterns application from the ServiceNow Store and to understand the prerequisites and supported device types.

    Prerequisites

    • SNMP credentials: Required to access Cisco UCS devices during discovery.
    • Applicative credentials: Must be created for the Cisco UCS Equipment CI type [cmdbciucsequipment] to enable pattern execution.

    Key Features

    • Classifier and Pattern: The UCS classifier uses the HorizontalDiscoveryProbe to launch the UCS-HD pattern.
    • SNMP OIDs: Discovery relies on specific SNMP Object Identifiers (OIDs) associated with Cisco UCS models to identify devices such as the UCS 6120XP, 6140XP, 6248UP, and 6296UP Fabric Interconnects.
    • Discovered Device Types: Only B-series UCS devices are discovered. The pattern excludes C, S, and E series devices.

    Data Collected and CMDB Population

    The discovery process populates multiple CMDB tables with detailed attributes for each device type:

    • Cisco UCS Equipment [cmdbciucsequipment]: Includes name, IP address, model, distinguished name, and UCS Manager version.
    • Cisco UCS Chassis [cmdbciucschassis]: Captures chassis name, model number, serial number, chassis ID, operational status, and distinguished name.
    • Cisco UCS Blade [cmdbciucsblade]: Details blade name, model, serial number, CPU count, core count, RAM, number of adapters, chassis and slot IDs, description, blade serial number, operational status, and distinguished name.
    • Cisco UCS Rack Mount Units [cmdbciucsrackunit]: Includes name, vendor, server ID, availability, UUID, rack serial, CPU count and cores, model ID, total memory, distinguished name, and state.

    Relationships Created

    To accurately represent the UCS environment, discovery establishes key relationships among discovered CIs:

    • Chassis contains blades.
    • Equipment contains rack mount units and chassis.
    • Servers run on blades.

    Practical Benefits for ServiceNow Customers

    This discovery capability simplifies the management and operational visibility of Cisco UCS infrastructure by automatically populating and updating the CMDB with accurate hardware details and relationships. This supports improved asset management, configuration auditing, and service impact analysis within ServiceNow.

    Discovery and Service Mapping Patterns application uses the to find Cisco UCS equipment, including chassis and blades. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Prerequisites

    Create SNMP credentials
    For more information, see SNMP credentials.
    Create applicative credentials
    Create applicative credentials for the Cisco UCS Equipment [cmdb_ci_ucs_equipment] CI type. For more information, see Applicative credentials.
    Classifier, pattern, and OIDs
    The UCS classifier uses HorzontalDiscoveryProbe to launch the UCS - HD pattern. The classifier also uses these SNMP OIDs, which specify the Cisco UCS Equipment [cmdb_ci_ucs_equipment] table:
    OID Manufacturer Model Table
    1.3.6.1.4.1.9.12.3.1.3.847 Unified Computing Cisco UCS 6120XP 20-Port Fabric Interconnect 1.4(3u)(NX-OS) 5.0 Aggregation Switch Cisco UCS Equipment
    1.3.6.1.4.1.9.12.3.1.3.899 Unified Computing Cisco UCS 6140XP 40-Port Fabric Interconnect 1.4(3u)(NX-OS) 5.0 Aggregation Switch Cisco UCS Equipment
    1.3.6.1.4.1.9.12.3.1.3.1062 Unified Computing Cisco UCS 6248UP 48-Port Fabric Interconnect 2.0(1t)(NX-OS) 5.0.2 Aggregation Switch Cisco UCS Equipment
    1.3.6.1.4.1.9.12.3.1.3.1063 Unified Computing Cisco UCS 6296UP 96-Port Fabric Interconnect 2.0(1t)(NX-OS) 5.0.2 Aggregation Switch Cisco UCS Equipment

    Data collected by Discovery during horizontal discovery

    Discovery populates the data in the CMDB when running the UCS - HD pattern pattern. Only B-series devices are discovered. The UCS - HD pattern does not find C, S, or E series devices.
