The CMDB CI Class Models store app adds or updates classes for the IBM Hardware Management Console (HMC).

The CMDB CI Class Models app adds class models that extend the CMDB class hierarchy, including class descriptions, identification rules, identifier entries, and, if applicable, dependent relationships. You can use the added classes just like any other CMDB class. Applications such as Discovery and Service Mapping Patterns can use the class extensions to populate CIs and discover technologies and software.

You will find full release notes for all CMDB CI Class Models releases at: https://www.servicenow.com/docs/bundle/store-release-notes/page/release-notes/store/it-operations-management/store-rn-itom-cmdb-class-models.html?emcs_t=S2h8ZW1haWx8Ym9hcmRfc3Vic2NyaXB0aW9ufE1FMlVTSFREVDc3S0hTfDMzNDcxMjV8U1VCU0NSSVBUSU9OU3xoSw

IBM Hardware Management Console (HMC)

The IBM HMC extension classes support discovery of IBM virtualization technology by providing:
  • Discovery of LPARs/FRAMEs, which SAM use cases need
  • Topology data of IBM HMC, which event correlation requires
  • Topology data for ITSM use cases, such as in-frame migration
