144.2 IBM VM/370 Planninq and System Generation Guide
Page of GC20-1801-10 As Updated April 1, 1981 by TNL GN25-0837 R DEVICE Macro The device types, 2540R and 2540P, refer to the same IBM 2540 Card
Read Punch (as do 1442P and 1442R, and 2520P and 2520R). Each
logical device must be specified in a separate RDEVICE macro.
In addition, any other device that can be attached to a real System/370 can be specified in the RDEVICE macro by its device
type. For unsupported devices that do not have a device type
listed under the DEVTYPE operand, you should code the subclass on
the CLASS operand. Then unsupported devices can be dedicated to a
virtual machine, and CP can log the error recordings, if there are
any. CP does not use unsupported devices for its own operations.
If a device specified in the RDEVICE macro is not supported by VM/370, the following MNOTE message (warning level) is generated: UNSUPPORTED DEVICE TYPE The device is generated as an unsupported device. An unsupported
device can only be used if it is dedicated to a virtual machine. It
is dedicated to a virtual machine if a DEDICATE control statement
is coded in the VM/370 directory for the virtual machine, or if it
is attached to it by the CP ATTACH command. Noig: If you code a 2702 device type the SETADDR value must be
specified.
MODEL=model
is the model letter and number for 3704 or 3705 or the model
number, if any, of a 2305, 3330, or 3333 device, or a tape device,
3278 display or 3203 printer. Model number, if not specified,
defaults to zero except that for the 3203 it defaults to 4. It
must be coded for 3330 devices, 3278 display, and 3203 printer. If
only a number' is coded for 3704 or 3705 devices, an MNOTE is
generated.
model is a value that can be: Device
1 or 2 2305 4 or 5 3203 1, 2, or 11 3330 1 or 11 3333 Al - H8 3704, 3705-1, or 3705-11 1, 2, 3, 4, 5, or 6 2415
5 or 7 2420 1, 2, or 3 3410 or 3411
3, 4, 5, 6, 7 or 8 3"20 1 3272 or 3274, Kodel 1B Notg§: 1. The 3277 Model 1 is a 480-character display screen and
is only supported by VM/370 as a dedicated device.
2. If a model number is included for devices that do not
require model numbers, the system generation is terminated
with an error message.
