Description: The IBM z13™ server is the newest IBM z Systems™ server, and distinct from the earlier zEnterprise® and other servers. In this publication, the IBM z13 server is referred to as the z13™. z/OS® V2R1 running on the z13 sets the groundwork for digital business by providing the foundation you need to support demanding workloads, such as operational analytics and clouds, alongside your traditional mission-critical applications.
The specific z13 functions, including base support, that are exploited by z/OS depend on the z/OS release. PTFs might be required for many of these functions. See Actions you can take before you order a z13 server for information about finding the appropriate PTFs.

Web deliverables are available from the z/OS downloads page: http://www.ibm.com/systems/z/os/zos/tools/downloads/index.html
| Element or feature: | Multiple. |
| When change was introduced: | IBM z13, which first shipped March 2015. |
| Applies to migration from: | z/OS V2R1, z/OS V1R13 and z/OS V1R12. |
| Timing: | Anytime before you introduce a z13 server into your environment. |
| Is the migration action required? | Yes, if you want to run z/OS V2R1, z/OS V1R13 and V1R12 on a z13 server, or if you want to run a Coupling Facility on a z13 server. If you will run only a Coupling Facility on a z13 system, then only the sysplex-related actions are relevant (though you will still need to install the appropriate z/OS service for the z/OS images running on other servers that use the z13 Coupling Facilities). |
| Target system hardware requirements: |
|
| Target system software requirements: | See Support is delivered by service, z/OS features, and web deliverables described in General recommendations and considerations for a z13 server and Install the necessary z/OS service, as indicated in PSP buckets described in Actions you can take before you order a z13 server. |
| Other system (coexistence or fallback) requirements: |
|
| Restrictions: | See Restrictions for a z13 server. |
| System impacts: | None. |
| Related IBM Health Checker for z/OS check: | A new health check for FICON dynamic routing, CHECK(IBMIOS,IOS_FABRIC_MONITOR), available via PTF for APAR OA40548 for z/OS V1R12, V1R13, and V2R1. This health check is designed to check all components of a dynamic routing fabric, the channel subsystem, and disk control units to make sure that dynamic routing requirements are met if dynamic routing has been enabled for one or more FICON switches. This support is intended to help you identify misconfiguration errors that can result in data integrity exposures. IBM Health Checker for z/OS check, SUP_HiperDispatchCPUConfig, is also added to z/OS V1R12 with APAR OA30476. This check will verify that HiperDispatch is enabled on a z196 or later system. |
Steps to take: Follow the General recommendations and considerations for a z13 server, adhere to the Restrictions for a z13 server, and perform the tasks described in the following topics.
