functions that are available on previous servers but no longer supported by z13s have been
removed.
For a list of supported functions and the z/OS and z/VM minimum required support levels, see
Table 7-3 on page 234For z/VSE, z/TPF, and Linux on z Systems, see Table 7-4 on page 239.
The tabular format is intended to help you determine, by a quick scan, which functions are
supported and the minimum operating system level that is required.
7.2.1 z/OS
z/OS Version 1 Release 13 is the earliest in-service release that supports z13s. After
September 2016, a fee-based service extension for defect support (for up to three years) can
be obtained for z/OS V1R13. Although service support for z/OS Version 1 Release 12 ended
in September of 2014, a fee-based extension for defect support (for up to three years) can be
obtained by ordering IBM Software Support Services - Service Extension for z/OS 1.12. Also,
z/OS.e is not supported on z13s, and z/OS.e Version 1 Release 8 was the last release of
z/OS.e.
z13s capabilities differ depending on the z/OS release. Toleration support is provided on z/OS
V1R12. Exploitation support is provided only on z/OS V2R1 and later. For a list of supported
functions and their minimum required levels, see Table 7-3 on page 234.
7.2.2 z/VM
At general availability, z/VM V6R2 and V6R3 provide compatibility support with limited use of
new z13s functions. For a list of supported functions and their minimum required support
levels, see Table 7-3 on page 234.
For the capacity of any z/VM logical partition (LPAR), and any z/VM guest, in terms of the
number of Integrated Facility for Linux (IFL) processors and central processors (CPs), real or
virtual, you might want to adjust the number to accommodate the processor unit (PU)
capacity of the z13s.
In light of the IBM cloud strategy and adoption of OpenStack, the management of z/VM
environments in zManager is now stabilized and will not be further enhanced. zManager
therefore does not provide systems management support for z/VM V6R2 on IBM z13s or for
z/VM V6.3 and later releases. However, zManager continues to play a distinct and strategic
role in the management of virtualized environments that are created by integrated firmware
hypervisors of the IBM z Systems. These hypervisors include IBM Processor
Resource/Systems Manager (PR/SM), PowerVM, and System x hypervisor based on a
kernel-based virtual machine (KVM).
