Symptoms
Error message: GDDS233E GDDR MSC SDDF Reset for group msc-groupname
delayed - (0919201821441111 - 45635.85 seconds ago)
Test di un trip ConGroup in un'ambiente SRDF/STAR eliminando i link tra i due siti nella relazione SRDF/S. GDDR (Geographically Dispersed Disaster Restart) che controlla l'ambiente.
I link vengono eliminati due volte. Dopo la prima interruzione del link e il trip ConGroup, le sessioni SDDF sono state ripristinate correttamente. Dopo la seconda eliminazione, una sessione SDDF ha esito negativo e viene emesso il messaggio GDDS233E. Il messaggio indica che la rotazione delle sessioni SDDF si è bloccata.
Vedere la sezione note per la sequenza di eventi che si verificano.
Cause
Dopo un errore di collegamento, l'elaborazione della sessione SDDF si interrompe in un'ambiente SRDF/STAR o SRDF/SQAR a causa di una logica di programma errata. Una mancata corrispondenza nei contatori, che devono essere aggiornati in modalità sincrona, non vengono aggiornati, causando un loop di polling.
Resolution
Soluzione alternativa
- È necessario riavviare l'ambiente MSC per abilitare la rotazione della sessione SDDF.
Correzione permanente
- Per Mainframe Enablers 8.3, sono stati sviluppati SF83083 PTF (Program Temporary Fix) e PTF SR83049 per risolvere il problema. Sono disponibili per il download dal supporto online Dell EMC.
- Per Mainframe Enablers 8.2, PTF SF82142 e PTF SR82088 sono stati sviluppati per risolvere il problema. Sono disponibili per il download dal supporto online Dell EMC.
- Per Mainframe Enablers 8.1, PTF SF81137 e PTF SR81096 sono stati sviluppati per correggere il problema. Sono disponibili per il download dal supporto online Dell EMC.
Additional Information
Il problema viene ricreato nell'ambiente di laboratorio Dell e viene visualizzata la seguente sequenza di eventi.
I link vengono rimossi nel mezzo di un SDDF RESET per le sessioni 2. I messaggi SCF1543E e SCF1523E indicavano il problema. Il RESET ha esito negativo con un codice errore 87. Il codice errore 87 è normale in questa situazione e indica che il comando remoto non è riuscito.

La rotazione SDDF continua a non riuscire con un errore syscall della chiamata remota 87.
Quando i link vengono riportati online, il primo RESET della sessione 2, sembra completarsi ma richiede un solo cambio di ciclo. Sono necessari quattro cicli per il completamento in una situazione normale. La rotazione della sessione sembra continuare normalmente.
