ISG185E
GRS CANNOT RESTART THE RING BECAUSE SYSTEMS ARE NOT RESPONDING

Explanation

The global resource serialization ring was disrupted while global resource serialization was using ring acceleration. Some or all of the systems that were in the complex are not responding. The last system to put requests into the ring-processing system authority (RSA) is not responding and the requests may have been granted by another non-responding system. Global resource serialization cannot rebuild the ring because it cannot get updated RSA information.

System action

The system issues ISG184I for each system that may have granted requests unknown to the rest of the global resource serialization complex. Global resource serialization waits until a system with updated RSA information responds or until all of the non-responding systems specified in message ISG184I have been removed from the complex.

All the systems in the complex suspend any task attempting to obtain global resources until global resource serialization restarts the ring.

Operator response

Do one of the following:
  • Follow the operator response for cross-system coupling facility (XCF) messages, (prefix IXC) or other critical system messages.
  • Remove the non-responding systems from the sysplex.

System programmer response

If this problem occurs frequently in the global resource serialization complex, consider either discontinuing the use of ring acceleration or increasing the ACCELSYS value specified in the GRSCNFxx parmlib member.
