* The NOCHECK function was introduced by APAR OY62560. Defining the storage system as a
single control unit allows all channel paths to access all DASD devices.
2105 Controller Emulation: To define a storage system CU image and the base and alias address
range that it will support, use the following example for HCD.
The following HCD steps correspond to the 2105 IOCP definition shown in the previous example.
IMPORTANT:
The HCD PAV definitions must match the configurations in the storage system. If not, error messages
are issued when the Hosts are IPL'd or the devices are varied online.
