HCD new functions to consider
New function for Hardware Configuration Definition (HCD).
PCIe UID support
Description: To provide the ability to enable/disable UID-checking for a logical partition a new attribute (UID) for PCIe functions is introduced and works in combination with the new partition attribute (uniqueness flag). A function has a unique UID if there is no other PCIe function accessible by the same partition that has the same UID defined.
When change was introduced: z/OS® V2R2.
Processor support
- processor types 2964-N30, -N63, -N96, -NC6, -NE1 (new support level H160930)
- processor types 2964-L30, L63, -L96, -LC6, -LE1 (supported level H160930)
- processor types 2965-N10 and N20 (support level H160930)
- processor types 2965-L10 and L20 (support level H160930)
When change was introduced: z/OS V2R2.
Support of new PCIe functions
- An ISM (Internal Shared Memory) network adapter allows a virtual PCIe function requiring a unique VCHID with up to 255 virtual function Ids. The ISM network adapter allows one PNETID to be specified which has to be identical for all virtual functions of a VCHID.
- An RCE (Regional Crypto Enablement) function is used for all IBM approved vendor crypto adapters.
When change was introduced: z/OS V2R2.
PCIe enhancement
Description: 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.
When change was introduced: z/OS V2R2.
Validation enhancement
Description: 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.
When change was introduced: z/OS V2R2.
Processor support
- processor types 2964-N30, -N63, -N96, -NC6, -NE1 (new support level H160310)
- processor types 2964-L30, -L63, -L96, -LC6, -LE1 (support level H160310)
- processor types 2965-N10 and N20 (support level H160310)
- processor types 2965-L10 and L20 (support level H160310).
When change was introduced: z/OS V2R2.
Support 6 Channel Subsystems and 4 Subchannel Sets
Description: For the new processor type the maximum number of channel subsystems is extended to 6 and the number of subchannel sets is increased.
When change was introduced: z/OS V2R1.
PCIe function enhancements
Description: With processor IBM z13 the PCIe functions of type ROCE now require a virtual number definition and allow only 2 PNET ID for its external physical network assignments.
When change was introduced: z/OS V2R1.
VCHID support for internal channels
Description: For internal channel paths, like IQD, there does not exist a physical correspondence to hardware, hence there does not exist a PCHID value. Instead a unique virtual channel ID (VCHID) is assigned. A VCHID value can arbitrarily be selected out of the supported range for valid PCHID values.
When change was introduced: z/OS V2R1.
New CS5 chpid type
Description: A new CHPID type CS5 based on PCIe technology is supported.
When change was introduced: z/OS V2R1.
Processor support
Description: HCD supports the IBM z13 processor family (processor types 2964-N30, -N63, -N96, -NC6, -NE1).
When change was introduced: z/OS V2R1.
