Statements of Directions1: Consider the following points:
•Future z/VM release guest support
z/VM V6.4 is the last release that is supported as a guest of z/VM V6.2 or older releases.
•Disk-only support for z/VM dumps
z/VM V6.4 is the last z/VM release to support tape as a media option for stand-alone, hard abend, and snap dumps. Subsequent releases will support dumps to ECKD DASD or FCP SCSI disks only.
•Discontinuance of support for separately ordered EREP licensed product
z/VM V7.1 is planned to be the last z/VM release to support EREP as a separately orderable and serviceable IBM licensed product. EREP functionality will continue to be delivered as part of the z/VM offering.
•Stabilization of z/VM Support for the IBM EC12 and BC12 server family
z/VM V7.1 is the last z/VM release that is planned to support the EC12 or BC12 family of servers. Therefore, an IBM z13 or an IBM z13s will be the required minimum level of server for future z/VM releases. See the IBM Support Portal for the most current z/VM support lifecycle information.
•Removal of the z/VM PAGING63 IPL parameter
z/VM V7.1 is the last z/VM release to support use of the PAGING63 IPL parameter. This parameter directed the paging subsystem to behave as it had in releases before z/VM V6.4. It also prevented use of z/VM V6.4 and V7.1 paging subsystem improvements, which include support for High-Performance FICON, HyperPAV, encryption, and EAV.

IOCP required level for z15 servers: The required level of IOCP for the z15 is IOCP 5.5.0 with PTFs. For more information, see the following publications:
•IBM Z Stand-Alone Input/Output Configuration Program User's Guide, SB10-7173
•IBM Z Input/Output Configuration Program User’s Guide for ICP IOCP, SB10-7172
|
Dynamic Partition Manager V4.0: Dynamic Partition Manager V4.0 is available for managing IBM Z servers that are running Linux. DPM 4.0 is available with HMC Driver Level 41 (HMC Version 2.15.0). IOCP does not need to configure a server that is running in DPM mode. For more information, see IBM Dynamic Partition Manager (DPM) Guide, SB10-7176.

Note: For zIIPs and IFLs, SMT must be enabled on z/OS, z/VM, or Linux on Z instances. An operating system with SMT support can be configured to dispatch work to a thread on a zIIP (for eligible workloads in z/OS) or an IFL (for z/VM) core in single-thread or SMT mode.

Consideration: Because coupling link connectivity with z14 does not support InfiniBand, introducing z15 into an installation requires extra planning. Consider the level of CFCC. For more information, see “Migration considerations” on page 200.
|
Requirement: All FICON channel path identifiers (CHPIDs) that are defined to the same LCU must support zHPF. The inclusion of any non-compliant zHPF features in the path group causes the entire path group to support command mode only.
|
Remember: The need for ICKDSF Release 17 also applies to systems that are not part of the same sysplex, or are running an operating system other than z/OS, such as z/VM.
|
Note: An optional feature can be ordered for WWPN persistency before shipment to keep the same I/O serial number on the new CPC. Current information must be provided during the ordering process.
|
Note: Operating system support is required to recognize and use the second port on the OSA-Express6S 1000BASE-T Ethernet feature.
|
Note: Operating system support is required to recognize and use the second port on the OSA-Express6S Gigabit Ethernet feature.
|
Note: Operating system support is required to recognize and use the second port on the OSA-Express5S Gigabit Ethernet feature.
|
Notes: Consider the following points:
•Operating system support is required to recognize and use the second port on the OSA-Express7S 1000BASE-T Ethernet feature.
•OSA-Express7S 1000BASE-T Ethernet feature supports only 1000 Mbps duplex mode (no auto-negotiation to 100 or 10 Mbps)
|
Note: Operating system support is required to recognize and use the second port on the OSA-Express6S 1000BASE-T Ethernet feature.
