ICP321I DEVICE CANNOT BE ACCESSED BY CSS `x`

Explanation
You specified CSS x in the PATH, PART,   PARTITION, or
NOTPART keyword in the IODEVICE statement. However, none of the control
units attached to the device have channel paths in that CSS.

System action
IOCP continues to validate and check the syntax of the remaining
statements. However, it does not generate an IOCDS and it does not
produce configuration reports. 

Programmer response
Ensure that the CSS ID specified is correct. Check the associated
CNTLUNIT and CHPID statements to ensure that there is a channel path
from the CSS through a control unit to the device.
