Step 1: Building An Input/Output Configuration Data Set (IOCDS)
It is the customers responsibility to supply an
I/O configuration source (IOCS) file
, consisting of card-image
input macroinstructions. The IOCS contains specific data about all attached control units and I/O devices.
It must be created in 80-column card-image format and can be provided on either tape (EBCDIC format
file) or 3.5-inch diskette (DOS, ASCII format file).
The IOCS is the input to the
I/O configuration program (IOCP)
. The IOCP loads the IOCS into the
processor and uses it to build the
I/O configuration data set (IOCDS)
.
If You Have Already Completed Building an IOCDS:
Go to “Step 2: Creating an Operations Group” on page 3-11
If the I/O Configuration Source is Available:
If the I/O configuration source file (card-image macroinstructions) has been previously prepared, then you
can begin the procedure of importing it to the Support Element and generating an IOCDS. Follow the
steps provided in “Step 1.1: Establishing a CPC Console Connection and Power-on Reset” on page 3-3.
If the I/O Configuration Source is NOT Available:
If no I/O configuration source file (card-image macroinstructions) is available, then you must create one at
installation time. The
Input/Output Configuration Program User Guide
, GC38-0401, Chapter 2, provides
instructions on the card-image format and syntax. After it is created, go to “Step 1.1: Establishing a CPC
Console Connection and Power-on Reset” on page 3-3.
