5.3.1 Defining the hardware ITSOSSI6 runs on a System z196. Table 5-2 shows our ITSOSSI6 system hardware definition. Both logical partitions (LPARs) share all DASD and have the same addressing.

Setting up the DASD We performed the following installation steps: 1. We attached the DASD to ITSOSSI5 and performed a dynamic device reconfiguration (DDR) copy of each of the volumes onto the DASD for ITSOSSI6. This copy of the volumes resulted in a second set of volumes with the same labels and owners as the ITSOSSI5 volumes. 2. You must not change the labels and owners of the DASD, because the SYSTEM CONFIG file still contains the ITSOSSI5 system ID. It is not possible to change it until the system is running. Also, the user directory contains references to the ITSOSSI5 volumes. 2 Optional priced features that are preinstalled on the z/VM V6.2 base product media Chapter 5.
