Problem summary
**************************************************************** * USERS AFFECTED: All IBM z14 ZR1 / LR1 D/T3907 running z/VM. * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** This APAR will provide support for the IBM z14 ZR1 and IBM z14 LinuxONE Rockhopper II (Model LR1) - D/T3907 and must be applied as part of upgrading z/VM to support the IBM z14 ZR1 / LR1 D/T3907. This APAR provides changes to CP Monitor in support of capacity planning for IBM z14 ZR1 / LR1 D/T3907 and newer models. NOTE: it is always recommended to apply the compatibility APARs to z/VM before upgrading your hardware. Migrating z/VM to the IBM z14 ZR1 / LR1 D/T3907: The IBM z14 ZR1 / LR1 D/T3907 compatibility PTF for z/VM 6.4.0 must be installed before moving your z/VM system to the IBM z14 ZR1 / LR1 D/T3907. Refer to the Red Alert noted in the PSP bucket to avoid IPL problems. Installing z/VM on the IBM z14 ZR1 / LR1 D/T3907: z/VM V6.4.0 can be installed directly on an IBM z14 ZR1 / LR1 D/T3907 server with a V640 install image obtained from IBM after August 25, 2017. The PTF for APAR VM65639 must be applied immediately after installing z/VM. SSI Considerations: The available PTF for prereq APAR VM65976 provides infrastructure support for ESA/390 compatibility mode within z/VM V6.2.0, V6.3.0, and V6.4.0, and must be installed on all members of an SSI cluster before any z/VM V6.3.0 or V6.4.0 member of the cluster is run on any IBM z14 model. For additional details see the PSP bucket: 3907DEVICE 3907/ZVM subset.
Problem conclusion
Temporary fix
Comments
A new field has been added to z/VM Monitor record MRMTRSYS (Domain 1, Record 4) to report the new Max PU value which contains a model dependent unsigned binary value which represents the maximum available processing cores potentially available to the system. If this value is 0, the Max PU value is not defined for this model.
