IEA037I LOSS OF TIMING ONLY LINK HAS BEEN DETECTED.
Explanation
This message is issued when z/OS® is notified that a timing-only coupling link has gone offline.
A timing-only coupling link is a link between two non-CF servers. The link is defined as timing-only using the Hardware Configuration Dialog (HCD).
System action
The system continues processing.
Operator response
Notify the system programmer. The same event may occur on the other server connected by the timing-only link.
System programmer response
If the link loss is not expected (that
is, a link manually taken offline), you'll need to determine what
caused the link failure. Additional detail can be gathered from various
sources:
- Message IEA037I will be issued on z/OS systems running on servers connected on both sides of the link (at z/OS V2R2 or later releases).
- Details can be found on the hardware message log using the HMC.
Monitor for additional z/OS messages which indicate a loss of redundancy as a result of link failure. For details on timing-only links, see section 2.2.2 of Server Time Protocol Planning Guide, SG24-7280.
