If an error occurs, check the MRES and SRES codes for the node in question, and correct the problem.

6-7-3 Response Codes and Troubleshooting

The table below lists response codes (main and sub-codes) returned after execution of the FINS commands, the probable cause of errors, and recom- mended remedies.

Upon receipt of some commands, the destination node will issue a request to another node; the other node is referred to as the third node.

Main code	Sub-	Probable cause	Remedy
	code
00: Normal completion	00	---	---
	01	Service was interrupted	Check the contents of the destination trans-
			mission area of third node.
			Check the data link status.
