    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, specifically chassis and blades, into the CMDB. This capability supports only B-series UCS devices and requires the latest Discovery and Service Mapping Patterns application available from the ServiceNow Store.

    Prerequisites

    • SNMP credentials: Must be created to allow access to UCS devices.
    • Applicative credentials: Required for the Cisco UCS Equipment CI type (cmdbciucsequipment).
    • Network connectivity: The MID Server must have HTTPS access (port 443) to the UCS Manager and be able to reach the management IP of UCS equipment.
    • UCS Manager account: Needs at least read-only role and permissions for executing XML API queries on specific UCS object classes such as computeRackUnit, equipmentChassis, computeBlade, and others.

    Discovery Process and Data Collection

    The discovery uses a classifier with HorizontalDiscoveryProbe to run the UCS - HD pattern, leveraging specific SNMP OIDs to identify Cisco UCS equipment models like 6120XP, 6140XP, 6248UP, and 6296UP fabric interconnects. Only B-series devices are discovered; C, S, or E series are not supported.

    Discovered data populates relevant CMDB tables:

    • Cisco UCS Equipment (cmdbciucsequipment): Contains general device info such as name, IP address, model, distinguished name, and UCS Manager version.
    • Cisco UCS Chassis (cmdbciucschassis): Stores chassis details including model number, serial number, chassis ID, operational status, and distinguished name.
    • Cisco UCS Blade (cmdbciucsblade): Captures blade-specific attributes like CPU count and cores, RAM, adapter count, slot and chassis IDs, serial number, status, and descriptions.
    • Cisco UCS Rack Mount Units (cmdbciucsrackunit): Holds rack unit data such as vendor, server ID, availability, UUID, serial, CPU and memory specs, model, distinguished name, and state.

    Relationships Created

    To accurately represent the UCS environment in the CMDB, the discovery establishes relationships between:

    • Chassis and blades (cmdbciucschassis contains cmdbciucsblade)
    • Equipment and rack units (cmdbciucsequipment contains cmdbciucsrackunit)
    • Equipment and chassis (cmdbciucsequipment contains cmdbciucschassis)
    • Blades and servers (cmdbciserver runs on cmdbciucsblade)

    These relationships help provide a comprehensive and accurate topology of Cisco UCS infrastructure within the ServiceNow CMDB.

    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 .
    Create applicative credentials
    Create applicative credentials for the Cisco UCS Equipment [cmdb_ci_ucs_equipment] CI type. For more information, see .
    Verify network connectivity
    Verify that the MID Server has HTTPS access to the UCS Manager on port 443 and is able to reach the management IP address of the UCS equipment.
    Verify UCS Manager account requirements
    Verify that the account has at least the read-only role in UCS Manager and has permissions to execute XML API queries for the following object classes:
    • computeRackUnit
    • equipmentChassis
    • computeBlade
    • mgmtIf
    • topSystem
    • versionEp
    • equipmentFan
    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.
