IST1504I
XCF CONNECTION WITH cp_name IS INOPERATIVE

Explanation

This message is the first message in a group of two messages that VTAM® issues when a cross-system coupling facility (XCF) READ/WRITE path to an adjacent node is no longer active. This message provides information about a potential problem and can be used to correlate VTAM diagnostic information with MVS™ diagnostic information. This message can be issued prior to the deactivation of an XCF local SNA PU, prior to an XCF group exit, or prior to the deactivation of a dynamic local SNA major node indicating that XCF connectivity has been terminated for that CP.

A complete description of the message group follows the example.
IST1504I  XCF CONNECTION WITH cp_name IS INOPERATIVE
IST1501I  XCF TOKEN = token
IST1504I
  • cp_name is the network qualified CP name of the adjacent VTAM.
IST1501I
  • token is the XCF token MVS assigned to the adjacent VTAM.

System action

Processing continues.

Operator response

  • You may want to reactivate the dynamic XCF local SNA PU or the dynamic local SNA major node (ISTLSXCF). Otherwise, no action is necessary.
  • You may want to save the system log for problem determination if the inoperative connection is critical to the network.

System programmer response

None.
