Integração entre Avamar e Data Domain: não é possível sincronizar certificados com a segurança da sessão ativada

Summary: Quando a segurança da sessão está ativada no Avamar, os certificados devem ser sincronizados entre o Avamar e o Data Domain. Isso requer que o protocolo SCP esteja habilitado no Data Domain. ...

Symptoms

Os backups de BMR podem falhar com o seguinte erro:

DDR result code: 5049, desc: file not found
DDR result code: 5341, desc: SSL library error "failed to import host or ca certificate automatically"
DDR result code: 5008, desc: invalid argument

Ao seguir o artigo da Dell 197106, Avamar and Data Domain Integration: DD exibido em vermelho no caminho de resolução da AUI e/ou interface do usuário do Avamar, os certificados não são gerados.

Ao verificar o MCS logs, há uma exceção relacionada ao protocolo SCP.

Cause

Analise a mcserver log:

/usr/local/avamar/var/mc/server_log/mcserver.log.0

Caused by: java.io.IOException: SCP unexpected cmd: Scp is disabled. Access denied.

Isso mostra que o protocolo SCP está desativado no Data Domain.

O fluxo de sincronização de certificados entre o Avamar e o Data Domain exige que o SCP seja ativado, conforme demonstrado abaixo:

  1. O Avamar executa um comando no Data Domain usando a chave pública do Data Domain para autenticação sem senha. O primeiro comando é gerar uma solicitação de assinatura de certificado (CSR) no Data Domain.
  2. Em seguida, o Avamar tenta copiar a CSR do Data Domain usando o SCP, mas não consegue quando o SCP está desativado no Data Domain.
  3. O Avamar usaria a CSR para assinar um certificado emitido para o Data Domain pela autoridade de certificação raiz do Avamar. No Data Domain, ele é chamado de imported-host DDBoost certificado.

Verificar a interface do usuário do Data Domain mostra que o SCP está desativado:
