z/OS on a Separate CPU

When z/OS is run on a separate CPU and a hardware RESERVE/RELEASE is required, define the minidisks for the TMC and Audit data sets as full-pack minidisks. For VM/ESA, mark the minidisks as SHARED=YES in the CP system configuration. Make sure the MDISK statement has a link mode of MWV.

Note: For more information about operating a system using RESERVE/RELEASE, or consult your IBM Support Center, see the section in the appropriate IBM planning and system generation guide.
