IRRI030I
RRSF CONNECTION {TO | FROM} system-identifier HAS BEEN REJECTED BECAUSE RACF COULD NOT VERIFY AT-TLS POLICY. THE service-name SERVICE TIMED OUT.

Explanation

RACF® remote sharing requires its connections to be covered by an AT-TLS rule. It is AT-TLS that provides the authentication of RRSF nodes to one another, and encryption of traffic across the network. RRSF uses the select() service (BPX1SEL) to force the underlying TLS handshake to occur so that the AT-TLS policy for this connection can be verified. The select() service timed out.

The value for direction can be TO, when the message is issued by the system that initiated the connection, or FROM, when the message is issued by the system that received the connection request.

When the value of direction is TO, system-identifier is expressed as NODE node-name, followed by SYSNAME system-name if the target is a multisystem node.

When the value of direction is FROM, the communication failed before RRSF identified the peer RRSF node and system name, or even determine if the peer is a valid RRSF system. Therefore, system-identifier is expressed as PEER followed by an IP address and a port number, separated by a colon. If necessary, you can use the z/OS® UNIX host command to map the IP address to a host name. For example, if the peer information displayed is 1.2.3.4:1026, issue the following command:
$ host 1.2.3.4                                     
EZZ8321I zossys1.xyz.com 1.2.3.4

System action

The connection is rejected. RRSF places the connection into the OPERATIVE-PENDING-VERIFICATION state.

System programmer response

After the condition is fixed, try the connection again with the TARGET OPERATIVE command for the failed node and system.

RACF Security Administrator Response

Look for AT-TLS trace records to see if the problem is related to AT-TLS policy setup. If so, fix the issue. If you are unable to determine the cause, contact IBM® service.
