An MVS™ console configuration consists of the various consoles that operators use to communicate with MVS. Your installation first defines the I/O devices it can use as MCS consoles with the hardware configuration definition (HCD). HCD manages the I/O configuration for the MVS system. You do not use HCD to define an SMCS console. To indicate to MVS which devices to use as MCS consoles, you specify the appropriate devices in the CONSOLxx parmlib member.
