Error message: GDDS233E GDDR MSC SDDF Reset for group msc-groupname
delayed - (0919201821441111 - 45635.85 seconds ago)
Prueba de un viaje ConGroup en un entorno SRDF/STAR mediante la eliminación de los enlaces entre los dos sitios en la relación SRDF/S. Reinicio en caso de desastres geográficamente dispersos (GDDR, por sus siglas en inglés) que controla el entorno.
Los vínculos se descartan dos veces. Después de la primera caída de enlace y el primer viaje de ConGroup, las sesiones de SDDF se recuperaron correctamente. Después de la segunda entrega, una sesión de SDDF falla y se emite el GDDS233E mensaje. El mensaje indica que la rotación de las sesiones de SDDF se detuvo.
Consulte la sección de notas para conocer la secuencia de eventos que se producen.
Cause
Después de una falla de enlace, el procesamiento de la sesión de SDDF se detiene en un entorno SRDF/STAR o SRDF/SQAR debido a una lógica de programa incorrecta. Una incompatibilidad en los contadores que se debe actualizar de manera síncrona no se actualiza, lo que provoca un bucle de sondeo.
Resolution
Solución alternativa
- Es necesario reiniciar el entorno de MSC para habilitar la rotación de sesiones de SDDF.
Corrección permanente
- Para Mainframe Enablers 8.3, se desarrollaron SF83083 de corrección temporal del programa (PTF) y SR83049 de PTF para corregir el problema. Están disponibles para descargar desde el servicio de soporte en línea de Dell EMC.
- Para Mainframe Enablers 8.2, se desarrollaron SR82088 de PTF SF82142 y PTF para corregir el problema. Están disponibles para descargar desde el servicio de soporte en línea de Dell EMC.
- Para Mainframe Enablers 8.1, se desarrollaron SR81096 SF81137 PTF y PTF para corregir el problema. Están disponibles para descargar desde el servicio de soporte en línea de Dell EMC.
Additional Information
El problema se vuelve a crear en el entorno de laboratorio de Dell y se observa la siguiente secuencia de eventos.
Los enlaces se quitan en medio de RESET SDDF para las sesiones 2. Los mensajes SCF1543E y SCF1523E indicaban el problema. RESET falla con un código de error de 87. El código de error 87 es normal en esta situación e indica que el comando remoto falló.

La rotación de SDDF continúa fallando con una falla de syscall remota 87.
Cuando los enlaces vuelven a estar en línea, el primer RESET de la sesión 2 parece completarse, pero solo se necesita un cambio de un solo ciclo. Se necesitan cuatro ciclos para completarse en una situación normal. La rotación de sesiones parece continuar de manera normal.
