We will get new hardware with 4 digit real address range (for Example AAF0 - AAFF).
How do we get 4 digit real addresses (AAF0 - AAFF) in VM attached to VSE as a 3 digit virtual addresses?
This can be realized by defining the DTMAPVSE Macro which is a part of the CA Dynam/T Tape Management for z/VM Macro (DTPARMS ASSEMBLE).
Steps to define the DTMAPVSE Macro:
Find out the CPUID and Serial Number from all VSE Systems communicating with DYNAMCMS (Best way is to run CAISERV report in every z/VSE System or issue AR command CA?).
Add every CPUID into the CPUPROF ASSEMBLE ... including the real CPU used in z/VM which should be defined as CPUID A...
This will be done by CA-Activator (enter Command CACT in CAIMAINT to call it)...
The Task to execute is Y423I001 in CA-CIS.
After that has been completed call Task TC30I021 Tailor DTMAPVSE Macro in the CA-Dynam/T Installation Tasks...
Define a DTMAPVSE macro Entry for every device in every CPUID defined in CPUPROF ASSEMBLE in Step 2.
DTMAPVSE CPU=B TYPE=3590 TAPE=(AF0)
DTMAPVSE CPU=A TYPE=3590 TAPE=(AAF0)
DTMAPVSE CPU=B TYPE=3590 TAPE=(AF1)
DTMAPVSE CPU=A TYPE=3590 TAPE=(AAF1)
Please define the first device for each CPUID, than the second device...
In the CA-DYNAM/T Tape Management for z/VM Systems Programmer Guide Page 4-4.
An example for the complete DTPARMS ASSEMBLE including DTMAPVSE Entries can be found.
For CA DYNAM/T VM users, please complete all the CA ACTIVATOR tasks that are in INCOMPLETE status including CA CIS task Y430I003 Gen. System Adapter Modules.
For the DYNVM EXTENSION of CA Dynam/T Tape Management for z/VSE, the DTPARMS ASSEMBLE file (residing on the DYNVM 191 Mdisk) need to be updated by XEDIT because CA-Activator is not available in this environment. Don't forget to regenerate DYNVM extensions via execution of TQINST and reply "Y" to questions IS THIS AN INITIAL INSTALL?
