Migrate to an IBM z13 or IBM z13s server

Description

Start of change The IBM z13™ (z13™) and IBM® z13s^TM (z13s) are the newest IBM z Systems™ mainframes, and are distinct from the earlier zEnterprise® and other systems. In this publication, these systems are referred to as the z13 and the z13s. z/OS® V2R2 running on the z13 or z13s sets the groundwork for digital business by providing the foundation you need to support demanding workloads, such as operational analytics and clouds, and your traditional mission-critical applications. End of change

In a Parallel Sysplex® that includes a z13 or z13s with either a z/OS system running in at least one LPAR or at least one LPAR being used as a coupling facility (CF), you can include the following servers:

z13 and z13s servers
zEC12 and zBC12 servers
zEnterprise servers (z196 or z114)

Start of change The specific z13 and z13s functions, including base support, that are used 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 or z13s server for information about finding the appropriate PTFs. End of change

Table 3. Information about this migration action
Table Note: IBM z Systems cryptography features include Visa Format Preserving Encryption technology (FPE), which is owned by Visa. Clients who wish to use the FPE functionality of IBM z Systems cryptography features must first enter into a separate agreement with Visa for use of this advanced technology; such Clients should contact either their Visa account manager or Visa at P2PE@visa.com. Clients who use IBM z Systems cryptography features, but do not make use of the FPE functionality, are not required to enter into any such agreement with Visa.
Element or feature:	Multiple.
When change was introduced:	IBM z13, which first shipped March 2015. z13s, which first shipped March 2016.
Applies to migration from:	z/OS V2R2, z/OS V2R1, and z/OS V1R13.
Timing:	Anytime before you introduce a z13 or z13s server into your environment.
Is the migration action required?	Yes, if you want to run z/OS V2R2, z/OS V2R1, or z/OS V1R13 on a z13 or z13s server, or if you want to run a coupling facility on a z13 or z13s server. If you plan to run only a coupling facility on a z13 or z13s system, only the sysplex-related actions are relevant. However, you must install the appropriate z/OS service for systems that are running on other servers that use the z13 or z13s coupling facilities.
Target system hardware requirements:	A z13 or z13s Additional hardware required for specific functions. IBM devices previously attached to zEC12, zBC12, and zEnterprise servers are supported for attachment to z13 or z13s channels, unless otherwise noted. The subject I/O devices must meet FICON architecture requirements IBM zAware requires the following server firmware: IBM zAware 10 pack FC #1010 IBM zAware 10 pack on a Disaster Recovery Server FC #1011 Flash Express requires FC #0403 zEDC Express requires FC #0420 10 GbE RoCE Express FC #0411 Use of IBMWebSphere DataPower® Integration Appliance XI50 for zEnterprise (DataPower XI50z) or select IBM BladeCenter PS701 Express blades or IBM BladeCenter HX5 blades requires a z BladeCenter Extension (zBX) Model 004 z BladeCenter Extension (zBX) Model 004 requires: AIX® 5.3, AIX 6.1, AIX 7.1 and up, and PowerVM® Enterprise Edition (on POWER7® blade) Red Hat RHEL 5.5, 6.0, 7.0 and up, SLES 10 (SP4), 11 (SP1), 12 and up, 64-bit only (on HX5 blade) Microsoft Windows Server 2012, Microsoft Windows Server 2012 R2, Microsoft Windows Server 2008 R2, and Microsoft Windows Server 2008 (SP2) (Datacenter Edition recommended), 64-bit only (on HX5 blade) Use of hardware acceleration for cryptographic operations, including the use of Visa Data Secure Platform (DSP) functions requires a CPACF (FC #3863) or a CEX5S (FC #0890) feature, or both. See Table Note 1. - Use of a Trusted Key Entry (TKE) workstation requires FC #0878.
Target system software requirements:	See the topic "Support is delivered by service, z/OS features, and web deliverables" in General recommendations and considerations for a z13 or z13s server and "Install the necessary z/OS service", as indicated in the PSP buckets that are described in Actions you can take before you order a z13 or z13s server.
Other system (coexistence or fallback) requirements:	It is recommended that you install and run the required service on your existing server. This will enable you to fall back from a hardware perspective, yet maintain your software level. If you have not installed the preconditioning and exploitation PTFs for CFCC Levels 17-19, note that those PTFs are required to be installed throughout your sysplex before implementing CFCC Level 20 or CFCC Level 21.. If you plan to implement zEDC, you should install the z/OS toleration PTFs on systems that access data that is compressed using zEDC Express on a z13 or z13s server. If you are using ICSF and plan to share keys with other z/OS systems that have an earlier level of ICSF, you should install the ICSF coexistence PTFs on those earlier levels of ICSF.
Restrictions:	See Restrictions for a z13 or z13s server.
System impacts:	None.
Related IBM Health Checker for z/OS check:	A health check for FICON dynamic routing, CHECK(IBMIOS,IOS_FABRIC_MONITOR), is available with the PTF for APAR OA40548 for z/OS V1R13 and V2R1, and included in z/OS V2R2. 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 is enabled for one or more FICON switches. This support is intended to help you identify misconfiguration errors that can result in data integrity exposures.

Steps to take

Follow the General recommendations and considerations for a z13 or z13s server, adhere to the Restrictions for a z13 or z13s server, and perform the tasks that are described in the following topics.
