Note: The default is only applied when the first system in a sysplex (or the only system) is IPLed. Installations that currently explicitly specify their mode of console operation are unaffected. Migration health check A migration health check was implemented for z/OS V1R11 and z/OS V1R12 through APAR OA32930. This is intended to encourage explicitly specifying the console mode. This health check becomes a "best practices" health check on z/OS V1R13 to encourage clients to migrate to distributed mode if they are found to be operating in shared mode. Figure 5-7 shows a display of the CNZ_CONSOLE_OPERATING_MODE health check on a z/OS V1R13 system where the console support mode was allowed to default.
