Sample IPL flow for sysplex under z/VM

If you are not familiar with the use of z/VM or with running z/OS as a guest under z/VM, the information in this appendix might prove helpful.

This appendix includes the following topic:

•Alternative configuration for a base sysplex

Alternative configuration for a base sysplex

If you are not familiar with z/VM or with running z/OS under z/VM, the commands shown in Example D-1 were issued to start both systems under z/VM. This example is based on the use of two Linux workspaces (named Linux 1 and Linux 2 in ...
