IXC406I

Explanation
During sysplex initialization, cross-system coupling
facility (XCF) determined that the system joining the sysplex is using
a different XCF external time reference (ETR) clock than the other
systems in the sysplex or that they are using the same ETR clock but
have different effective clock values. All systems in a sysplex must
use the same ETR clock and have the same effective clock value.
If
the EFFECTIVE CLOCK VALUES ARE NOT CONSISTENT message appears
in the message text, XCF has determined that the systems in the sysplex
are using the same ETR clock but have effective clock values.This is the ETR time with the LPAR EPOCH applied. A
difference of more than one second is deemed as a mismatch in timing
information.
In the message text: xx
The identifier of the ETR clock used by the IPLing system. If
the IPLing system is not using an ETR, the message text contains NET
ID=LOCAL.

yy
The identifier of the ETR clock used by the other systems in the
sysplex.

System action
The system issues message IXC420D,
or the system restarts XCF and issues message IXC207A to request
a new COUPLExx specification.

Operator response
Check the status of the ETR, or any defined
offsets to the ETR time, and notify the system programmer.

System programmer response
Have the operator do one of the following: Specify the COUPLE00 parmlib member on this system to IPL it in
XCF-local mode.  None of the multisystem XCF services will be available.
Request a different COUPLExx parmlib member to specify a different
couple data set.
Correct any ETR problem and retry with the same COUPLExx parmlib
member.
Enter a VARY XCF command to remove any systems in the sysplex
that are not connected to the correct ETR clock.
Correct any improperly defined ETR time offsets.

If the problem persists, search problem reporting data
bases for a fix for the problem.  If no fix exists, contact the IBM® Support Center.
