Description

The following changes in hardware support could affect your environment. Make the appropriate changes, as needed.

Removal of support for running an operating system in ESA/390 architecture mode. The z13™ and z13s^TM are the last z Systems™ servers to support running in ESA/390 mode. All future systems will only support operating systems running in z/Architecture® mode. However, all 24-bit and 31-bit problem-state application programs originally written to run on the ESA/390 architecture will be unaffected by this change.
Removal of support for Classic Style User Interface on the Hardware Management Console and Support Element. The z13 and z13s are the last z Systems servers to support Classic Style User Interface. In the future, user interface enhancements will be focused on the Tree Style User Interface.
Removal of support for the Hardware Management Console Common Infrastructure Model (CIM) Management Interface. The z13 and z13s are the last z Systems servers to support the Hardware Console Common Infrastructure module (CIM) Management Interface. The Hardware Management Console Simple Network Management Protocol (SNMP), and Web Services Application Programming Interfaces (APIs) will continue to be supported.
Removal of FICON® Express8 support. The z13 and z13s are the last z Systems servers to support FICON Express8. You should begin migrating from FICON Express8 channel features (#3325, #3326) to FICON Express16S channel features (#0418, #0419). FICON Express8 will not be supported on future high-end z Systems servers as carry forward on an upgrade.
Removal of support for ordering FICON Express8S channel features. Enterprises that have 2GB device connectivity requirements must carry forward these channels.
Removal of an option for the way shared logical processors are managed under PR/SM™ LPAR. The z13 and z13s are the last z Systems servers to support selection of the option "Do not end the timeslice if a partition enters a wait state" when the option to set a processor run-time value has been previously selected in the CPC RESET profile. The CPC RESET profile applies to all shared logical partitions on the machine, and is not selectable by logical partition.
Removal of support for configuring OSN CHPID types. OSN CHPIDs are used to communicate between an operating system instance running in one logical partition and the Communications Controller for Linux (CCL) product in another logical partition on the same CPC. See announcement letter #914-227 dated 12/02/2014 for details regarding withdrawal from marketing for the CCL product.
