    Prerequisites

    • Ensure you are using Discovery and Service Mapping Patterns
    • Set SNMP credentials for the enclosure (to be used by the Classifier)
    • Set the Basic Auth SSH credentials for the enclosure’s Onboard Administrator (to be used by the Discovery Pattern)
    • Discovery runs against the Onboard Administrator’s IP address.
    • Ensure that the host machine is reachable from the MID Server.

    Authentication & Authorization

    Configure the enclosure’s Onboard Administrator Basic Auth credentials. The account used for accessing the Onboard Administrator must have permissions to view all of the enclosure’s bays, so it can gather the blade servers' information.

    Highlights and Limitations

    The pattern has been tested against:
    • HPE BladeSystem c7000 Enclosure G2 and G3
    • HPE BladeSystem blades: HPE ProLiant BL460c
      • Generations 8, 9 and 10
      • ROM Versions: I31, I36, I41 (2014-2021)
      • Blades being managed by a Virtual Connect Manager/Virtual Connect Enterprise Manager (VCM/VCEM) have a logical serial number. In this case, the serial number, which is exposed by WMI, for example, is the logical one, rather than the physical one, as is usually the case. When creating the relation between the blade and the OS server, based on the serial number, the system attempts to match both the physical and logical serial numbers with the ones owned by the OS Server.
      • When discovering blade servers with the logical serial numbers, their logical serial numbers are inserted to cmdb_serial_number with the logical type. This is a new serial number type that was created to support these new serial numbers introduced by HP.
        Note:
        The WMI provides the logical serial number as the bios serial number. ESXi servers are discovered by probes. The ESXiserver CI gets the logical serial number as chassis.
