12.2.10 Migration considerations

A DS6000 will be supported as an IBM 2105 for z/OS systems without the DFSMS and z/OS SPE installed. This will allow customers to roll the SPE to each system in a sysplex without having to take a sysplex-wide outage. An IPL will have to be taken to activate the DFSMS and z/OS portions of this support.

12.2.11 Coexistence considerations

Support for the DS6000 running in 2105 mode on systems without this SPE installed will be provided. It will consist of the recognition of the DS6000 real control unit type and device codes when it runs in 2105 emulation on these down-level systems. Input/Output definition files (IODF) created by HCD may be shared on systems that do not have this SPE installed.

12.3 z/VM enhancements

z/VM is an IBM operating system that supplies a virtual machine to each logged-on user. The DS6000 will be supported on z/VM 4.4 and higher.

Important: Always review the latest Preventative Service Planning (PSP) 1750DEVICE bucket for software updates.

12.4 z/VSE enhancements

z/VSE is a system that consists of a basic operating system (VSE/Advanced Functions) and any IBM-supplied and user-written programs required to meet the data processing needs of a user. VSE and the hardware that it controls form a complete computing system. The DS6000 will be supported on:

￿z/VSE 3.1 and higher.
