GLOBAL RESOURCE SERIALIZATION HAS BEEN DISRUPTED. GLOBAL
RESOURCE REQUESTORS WILL BE SUSPENDED.
Explanation
The global resource serialization ring is disrupted.
Possible reasons are:
- An operator stopped one of the active global resource serialization
systems.
- An active global resource serialization system was removed from
the sysplex.
- A system in the global resource serialization ring is responding
slowly, possibly because it is issuing an SVC dump.
- Communication loss exists between systems in the sysplex.
- A software error occurred in global resource serialization processing
on one of the global resource serialization systems.
- An error occurred in the cross-system coupling facility (XCF)
services that global resource serialization used to communicate between
systems in the sysplex.
System action
All active global resource serialization systems,
including this one, become inactive to global resource serialization.
All the inactive systems suspend any task that attempts to obtain
global resources. If a software error occurred on one of the global
resource serialization systems, the system may issue message ISG177E
to the system log (SYSLOG) of that system.
The inactive global
resource serialization systems will rebuild the global resource serialization
ring.
Operator response
If any of the systems that were in the ring
do not become active global resource serialization systems when the
ring is rebuilt, notify the system programmer.
