Explanation
A system is trying to join a sysplex, but has not
established signalling connectivity for the systems listed in the
message text.
The problem is one of the following:
- The definitions for signalling paths to the systems listed are
missing from the COUPLExx member.
- The other side of a signalling path has not been defined to XCF
on a listed system.
- A failure prevented XCF from establishing valid signalling paths
using the signalling path definitions in the COUPLExx parmlib member.
- Not enough time has elapsed for XCF to establish the signalling
path.
In the message text:
- system-names
- A list of systems to which the initializing system has not established
signalling connectivity.
System action
If the initializing system does not appear to
have enough paths defined to establish signalling connectivity message
IXC453I is issued. Message IXC455D is then issued. System initialization
stops until the operator responds to message IXC455D.
Operator response
See the operator response for message IXC455D.
System programmer response
Ensure that signalling paths between
every pair of systems are defined and operational.
