Operating Systems Summary; Support By Operating System - IBM z13s Technical Manual

7.1 Operating systems summary

Table 7-1 lists the minimum operating system levels that are required on the z13s. For similar
information about the IBM zBX Model 004, see 7.15, "IBM z BladeCenter Extension (zBX)
Model 004 software support" on page 304.
End-of-service operating systems: The operating system levels earlier than those in
Table 7-1 are no longer in service, and are not covered in this publication. These older
levels might provide support for some features.

a. Regular service support for z/OS V1R12 ended September 2014. However, by ordering the
IBM Software Support Services - Service Extension for z/OS V1.12, fee-based corrective
service can be obtained up to September 2017.
b. z/VM V6R2 with PTF provides compatibility support (CEX5S with enhanced crypto domain
support)
c. z/VM supports both 31-bit and 64-bit mode guests.
d. 64-bit distributions included the 31-bit emulation layer to run 31-bit software products.
Features: Usage of certain features depends on the operating system. In all cases, PTFs
might be required with the operating system level that is indicated. Check the z/OS, z/VM,
z/VSE, and z/TPF subsets of the 2965DEVICE PSP buckets. The PSP buckets are
continuously updated, and contain the latest information about maintenance:
Hardware and software buckets contain installation information, hardware and software
service levels, service guidelines, and cross-product dependencies.
For Linux on z Systems distributions, consult the distributor's support information.

SG24-8332.

7.2 Support by operating system

The IBM z13s introduces several new functions. This section addresses support of those
functions by the current operating systems. Also included are some of the functions that were
introduced in previous z Systems and carried forward or enhanced in z13s. Features and
