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

    The Cisco Unified Computing System (UCS)-HD device discovery enables ServiceNow customers to automatically identify and map Cisco UCS equipment including chassis and blades within their infrastructure. This capability is delivered through the Discovery and Service Mapping Patterns application, which may require updating to the latest version from the ServiceNow Store for optimal functionality. The discovery process focuses on B-series devices and populates critical configuration item (CI) data into the Configuration Management Database (CMDB).

    Prerequisites

    • SNMP Credentials: Create SNMP credentials necessary for accessing UCS equipment.
    • Applicative Credentials: Set up applicative credentials specifically for Cisco UCS Equipment CI type to enable authenticated discovery.
    • Network Connectivity: Ensure the MID Server has HTTPS access on port 443 to the UCS Manager’s management IP.
    • UCS Manager Account: Verify that the account used has at least read-only permissions and rights to execute XML API queries on key UCS object classes such as computeRackUnit, equipmentChassis, and computeBlade.

    Discovery Mechanism and Data Collected

    The discovery uses a UCS classifier with a HorizontalDiscoveryProbe that triggers the UCS - HD pattern leveraging specific SNMP OIDs to identify UCS Equipment models such as 6120XP, 6140XP, 6248UP, and 6296UP fabric interconnects.

    During discovery, detailed information about UCS components is collected and stored in the CMDB across multiple CI classes:

    • Cisco UCS Equipment: Includes attributes like name, IP address, model, distinguished name, and UCS Manager version.
    • Cisco UCS Chassis: Includes model number, serial number, chassis ID, operational status, and distinguished name.
    • Cisco UCS Blade: Covers model number, serial number, CPU count, RAM, number of adapters, slot and chassis IDs, operational status, and more.
    • Cisco UCS Rack Mount Units: Includes vendor, server ID, availability, UUID, rack serial number, CPU and memory details, and state.

    Relationships Created

    To support comprehensive mapping and service impact analysis, the discovery automatically creates CI relationships such as:

    • Chassis containing blades
    • Equipment containing rack units and chassis
    • Servers running on UCS blades

    Practical Benefits for ServiceNow Customers

    By implementing Cisco UCS-HD device discovery, customers can:

    • Automatically populate and maintain accurate, detailed UCS hardware asset data in the CMDB.
    • Understand relationships between UCS components and servers, improving visibility into infrastructure dependencies.
    • Leverage up-to-date discovery patterns for effective management, troubleshooting, and service mapping of Cisco UCS environments.

    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.
    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

    1.3.6.1.4.1.9.12.3.1.3.1063 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.
