DFS2001I OPNDST ACCEPT FAILED NODE `x`.
USER `zzzzzzzz` SENSE=`yyyy` | |RCFBK=`xxxx`

Explanation

IMS tried to issue a VTAM® OPNDST with the ACCEPT option, but it was unsuccessful. VTAM previously told IMS that the terminal was available for OPNDST.

In the message text:

zzzzzzzz: The user name or N/A if there is no user
yyyy: The value is the VTAM sense code
xxxx: The value is the VTAM return code and feedback (RCFBK=) if specified

System action

IMS operation continues without the node.

Operator response

(master terminal) Determine why VTAM refused the OPNDST by using the VTAM D NET command; then try again.
