Using the Primary System Operator Console

The primary system operator console is the console where CP automatically logs on the primary system operator virtual machine during IPL. This can be the Hardware Management Console, or a device specified during the IPL. If SYSC is specified, the Operating System Messages panel becomes the system operator console. If SYSG is specified, the integrated 3270 console becomes the system operator console. Your installation chooses what device or what Hardware Management Console function (SYSC or SYSG) is identified as the primary system operator console using one of the following:

• System configuration statement, OPERATOR_CONSOLES
• IPL parameter, CONS=xxxx
• Load parameter CONSxxxx

The primary system operator console is where you perform most of the tasks in this book. For example, you enter CP commands from the primary system console to perform the following tasks:

• Bringing up the z/VM® CP
• Shutting down the z/VM CP
• Controlling z/VM devices
• Communicating with z/VM users
• Responding to z/VM errors
• Collecting information about z/VM operation.
