A configuration parameter may be incorrect.
To determine the configuration parameter that was identified as a possible problem, search for the error in the Service Action Log and display the failing item information for the error. The failing item description associated with this symbolic FRU identifies the parameter that may be the problem.
The configuration parameter that was identified as a possible problem can be verified by displaying the asynchronous control unit description with the DSPCTLD command.
The control unit description was created by the CRTCTLASC command. You may need to review the CRTCTLASC command information to determine if the suspected configuration parameter is wrong.
Information about commands related to communications can be found in the following manuals:
Some software problems can be temporarily solved by changing the configuration parameter, even if the original value was correct. Report this problem to your service representative if you see this temporary change.
