Migrate to an IBM zEnterprise z196 or z114 server

Description: An IBM zEnterprise System includes a Central Processing Complex (CPC), either the IBM zEnterprise 196 (z196) server or the IBM zEnterprise 114 (z114) server, or both, the zEnterprise BladeCenter Extension (zBX) with its integrated optimizers or select IBM blades, and the zEnterprise Unified Resource Manager (Unified Resource Manager).

The z114 is an entry-level enterprise server with a smaller mainframe footprint than the IBM zEnterprise 196 (z196).

The specific zEnterprise functions including base support that are exploited by z/OS® depend on the z/OS release, Table 1 lists the z/OS functions that are included in the base support for the release. Table 2 lists new functions that can be exploited by the release. For appropriate PTFs that might be required, see Actions you can take before you order a z196 and z114 server.

Element or feature:

Multiple.

When change was introduced:

The IBM zEnterprise 114 (z114), which shipped in September 2011.
The IBM zEnterprise 196 (z196), which first shipped in September 2010.
The IBM zEnterprise BladeCenter Extension (zBX), which shipped November 2010.

Applies to migration from:

z/OS V2R1, z/OS V1R13, and z/OS V1R12.

Timing:

Anytime before you introduce a z114 or z196 server into your environment.

Is the migration action required?

Yes, if you want to run z/OS V2R1, V1R13, or V1R12 on a z114 or z196 server, or if you want to run a Coupling Facility on a zEnterprise server. If you will run only a Coupling Facility on a z114 or z196 serversystem, then only the sysplex-related actions are relevant.

Target system hardware requirements:

A z196 or a z114 server.
Additional hardware required for specific functions.
- zDAC requires:
  - Up-to-date controller microcode
  - Up-to-date switch microcode
- IBM zEnterprise Blade Center Extension (zBX) is required for the IBM Smart Analytics Optimizer for DB2 for z/OS V1.1, the IBM WebSphere DataPower Integration Appliance XI50 for zEnterprise (DataPower XI50z), and select POWER7 and IBM System x blades.
- An IBM System Storage® DS5020 is required for IBM Smart Analytics Optimizer.

Target system software requirements:

See the list of PTFs in the Software Service Level section of the PSP buckets.
See Install the necessary z/OS service, as indicated in PSP buckets described in General recommendations and considerations for z196 and z114 servers.

Other system (coexistence or fallback) requirements:

It is recommended that you install and run the z114 or z196 required service on your existing server. This will enable you to fall back from a hardware perspective, yet maintain your software level.
The PTFs to support CFCC Level 17 have coexistence (or sysplex preconditioning) PTFs that are required to be installed throughout your sysplex before implementing CFCC Level 17.

Restrictions:

See Restrictions for a z196 or z114 server.

System impacts:

None.

Related IBM Health Checker for z/OS check:

IBM Health Checker for z/OS check, SUP_HiperDispatchCPUConfig, is added to z/OS V1R12 and available on z/OS V1R11. This check will verify that HiperDispatch is enabled on a zEnterprise system. (For more information, see "HiperDispatch cache and affinity node changes" in Migration and exploitation considerations for z196 and z114 server functions).

Note: The default of HIPERDISPATCH option in IEAOPTxx parmlib member was changed in z/OS V1R13 as follows:

For IBM zEnterprise 196 (and follow-on processors): YES
For IBM System z10 processors: NO

Steps to take: Follow the General recommendations and considerations for z196 and z114 servers, adhere to the Restrictions for a z196 or z114 server, and perform the tasks described in the following topics.
