Problem summary
**************************************************************** * USERS AFFECTED: All users of z/OS 2.1 (HBB7790) and * * above. * **************************************************************** * PROBLEM DESCRIPTION: New function: WLM support for hardware * * absolute group capping by LPAR firmware * * * * With the new z13 hardware function, * * hardware absolute group capping * * customers can specify the physical * * usage of processors within a group of * * logical partitions on the HMC. * * WLM has been updated to recognizes * * the LPAR capacity limit inherited * * by the hardware group. * **************************************************************** * RECOMMENDATION: * **************************************************************** New function Module IRASR204 class SRMLCCT method GetOtherValules has been changed to get the hardware group capacity value from IRAD204 (LcctHardwareGroupCpuTypeCapCp). Module IRASR204 class SRMLCCT method CalculateCapacity calculates the image capacity. The hardware group capping value is now considered in the image capacity calculation. It is the minimum of the following: 1. the minimum of Softcap and GroupLimit if there is one 2. capacity based on full use of all logical CPs 3. capacity based on weight if the partition is capped 4. capacity based on PR/SM capping limit (unit: # of CPUs) 5. capacity based on HardwareGroup cap limit (unit: # of CPUs) Similarly, methods Calculate_Free_LPAR_capacity and Calculate_LPAR_capacity in IRAPAPCA both include the hardware group capping value in the MINIMUM calculation. Module IRASRCPC has been updated to now consider the hardware group capping value in its calculation of the minimum image capacity. The result is propogated to the RCTIMGWU field. The image capacity is reported via Sysevents QVS and REQLPDAT. IRABAINI has been updated to obtain and store the hardware group capping values. IRABASSI now takes the Hardware Group capping value into consideration when calculating the LPAR capacity limit. It calculates the LPAR capacity limit as the minimum of the capacity defined by the number of LCPs, the PR/SM absolute capping value, and the HardwareGroup capping value. IRASMF99 includes new fields: HWGroupname + HWGroupCpuTypeCap (Cp/Ziip/Zaap) IRAPASS1/SRMSMF copies the new fields to SMF99 record subtype1.
