IBM constantly improves z/OS Hardware Configuration Definition both from a functional as well as a usability point of view. The following gives a short overview of past enhancements:
Support of new PCIe functions
Two new PCIe function types are supported - ISM and RCE:
The definition of PCIe functions for virtual functions of an adapter is now easier because 'Add PCIe function' offers a new field 'Number of virtual function' which helps to define multiple functions for one CHID at a time by incrementing the Virtual Function ID.
At Build production time it is checked if for those PCIe functions using PNETIDs a channel path exists which is accessing at least one identical LPAR and has the same PNETID defined. Chpids and PCIe functions requiring a VCHID (currently CHPIDs of type IQD and functions of type ISM) now require a processor unique PNETID.
HCD supports the IBM® IBM z13 processor family:
