Cause

Esse problema resulta de um problema de compatibilidade com a compilação da biblioteca do DD Boost versão 7.2.0.5 654364 incorporada nos clients WC e NC do Avamar 19.3.100-149. O problema acontece quando esses clients se conectam a sistemas Data Domain que executam o DD OS 7.2.0.40-664052 ou posterior.

Resolution

Faça upgrade de todos os clients Avamar WC e NC afetados para o Avamar versão 19.4 ou posterior.

Finalize as etapas abaixo:

  1. Faça download do software client Avamar 19.4 para o sistema operacional apropriado.
  2. Faça upgrade do Avamar Client em todos os sistemas afetados.
  3. Verificar o registro bem-sucedido do client e a conectividade com o sistema Data Domain.
  4. Execute backups de teste para confirmar a operação normal.

Nenhuma alteração de configuração ou solução temporária está disponível para clients Avamar 19.3.100-149 com as versões afetadas do DD OS.

Additional Information

  • Os clients Avamar 19.3.100-149 não são compatíveis com o Data Domain OS 7.2.0.40-664052 ou posterior ao usar a biblioteca DD Boost incorporada.
