Purpose: Use the DISPLAY U command to help you keep track of the status of the devices attached to the system. This command lets you request the status of:

Parameters

The device type for which the system is to display unit status information. You can enter any one of the following operands for device type:

The system is to display information about only those devices of the specified device type that are online. If you do not specify a device type, the system displays information about all online devices.

The system is to display information about only those devices of the specified device type that are offline. If you do not specify a device type, the system displays information about all offline devices.

devnum,nnnnn

The system is to display unit status information about devices starting with device number devnum for nnnnn number of devices. devnum is a 3-digit hexadecimal device number.

If you omit the device number, the system assumes the starting device number is X'000'.  If you omit the number of devices and do not specify ALLOC, the system assumes the number of devices is 256.

L=a

Specifies the display area (a) where the display will be presented. For cc, you must specify a decimal number from 1 to 99.

If you omit this operand, the display is presented in the first available display area or the message area of the console through which you enter the command (unless routing instructions are in effect; see the MSGRT command later in this chapter).
