When attempting to activate an MPC TRL connection over CTC, an IST380I message is displayed with sense code 80020000 (data link failure).

Resolving the problem
The problem is in the IOCDS (Input/Output Configuration Dataset) configuration. The IOCDS had two problems:
- The IODEVICE statements did not specify the logical partitions (LPARs) that can access the device.
- The RESOURCE statement that defines the LPAR names was omitted.
The PART operand on the IODEVICE statement specifies the device candidate list that identifies the LPARs that can access the device. An LPAR cannot access a device if the LPAR is not specified in the device candidate list for the device, even if the LPAR can access a channel path assigned to the device.
Add the required RESOURCE statement and modify the IODEVICE statements to include the PART operand.
For more information, see Chapter 2 "IOCP Statements and Functions" in zSeries Input/Output Configuration Program User's Guide for IYP IOCP .
