Error message: GDDS233E GDDR MSC SDDF Reset for group msc-groupname
delayed - (0919201821441111 - 45635.85 seconds ago)
Testando uma viagem de ConGroup em um ambiente SRDF/STAR descartando os links entre os dois locais no relacionamento SRDF/S. GDDR (Geographically Dispersed Disaster Restart) controlando o ambiente.
Os links são descartados duas vezes. Após a primeira queda do link e a viagem do ConGroup, as sessões do SDDF foram recuperadas com sucesso. Após a segunda queda, uma sessão do SDDF falha e a mensagem GDDS233E é emitida. A mensagem indica que o rodízio das sessões do SDDF foi paralisado.
Consulte a seção de notas para ver a sequência de eventos que ocorrem.
Cause
Após uma falha de link, o processamento da sessão do SDDF é interrompido em um ambiente SRDF/STAR ou SRDF/SQAR devido à lógica incorreta do programa. Uma disparidade nos contadores que deveriam ser atualizados de modo síncrono não são atualizados, causando um loop de consulta.
Resolution
Solução temporária
- Uma reinicialização do ambiente MSC é necessária para ativar o rodízio de sessão do SDDF.
Correção permanente
- Para o Mainframe Enablers 8.3, SF83083 e SR83049 PTF do Program Temporary Fix (PTF) foram desenvolvidos para corrigir o problema. Eles estão disponíveis para download no suporte on-line da Dell EMC.
- Para o Mainframe Enablers 8.2, SF82142 PTF e PTF SR82088 foram desenvolvidos para corrigir o problema. Eles estão disponíveis para download no suporte on-line da Dell EMC.
- Para o Mainframe Enablers 8.1, SF81137 PTF e PTF SR81096 foram desenvolvidos para corrigir o problema. Eles estão disponíveis para download no suporte on-line da Dell EMC.
Additional Information
O problema foi criado novamente no ambiente de laboratório da Dell e a sequência de eventos a seguir é observada.
Os links são removidos no meio de um SDDF RESET para as sessões 2. As mensagens SCF1543E e SCF1523E indicavam o problema. Falha em RESET com um código de erro 87. O código de erro 87 é normal nessa situação e indica que o comando remoto falhou.

O rodízio de SDDF continua a falhar com uma falha de syscall de chamada remota 87.
Quando os links são colocados on-line novamente, o primeiro RESET da sessão 2, parece ser concluído, mas é necessário apenas um switch de ciclo único. Em uma situação normal, são necessários quatro ciclos para serem concluídos. O rodízio de sessões parece continuar normalmente.
