Using HCD to Define an XP1024/XP12000/XP10000 LCU and the Base and Alias
Devices
The following example shows the sequence of HCD windows used in defining an
XP1024/XP12000/XP10000 LCU and a range of base and alias devices. Before you can define the LCU,
the channel paths must already be defined.
To define an XP1024/XP12000/XP10000 LCU and the base and alias address range that it will support,
use the following example for HCD:
1. From an ISPF/PDF primary options menu, select the HCD option to display the Basic HCD window. On
this window, verify the name of the IODF or IODF.WORK I/O definition file to be used.
2. From the Basic HCD window, select option 1 to display the Define, Modify, or View Configuration Data
window (see the following example).

Unit panel (see the following example).
