This section contains special considerations for EREP reports that contain information about the IDSK.
This subsystem is internal to a processor and is defined to the operating system as the type of control unit/DASD that is being emulated (for example: 3990-06/3390-03). Addresses with these devices are selected with the same parameter as the emulated device (for example: DEV=(3390) or DEV=(33XX) - NOTE: DEV=(IDSK) is NOT valid).
Only the emulated device type will appear on this report.
Bytes 54 and 55 of the OBR contain the OBR code of the device the IDSK is emulating (for example: x'2024' for a 3390-03). The OBR code of the IDSK is in the ECKD sense data later in the record. See "OBR Codes" in Chapter 7.
Byte 4 of the MDR contains the MDR code of the device the IDSK is emulating (for example: x'24' for a 3390-03). The MDR code of the IDSK is in the ECKD sense data later in the record. See "MDR Codes" in Chapter 7.
