Integracja Avamar i Data Domain: Nie można zsynchronizować certyfikatów z włączonymi zabezpieczeniami sesji

Summary: Po włączeniu zabezpieczenia sesji w systemie Avamar certyfikaty muszą być synchronizowane między rozwiązaniem Avamar i Data Domain. Wymaga to włączenia protokołu SCP w Data Domain.

Symptoms

Tworzenie kopii zapasowych może zakończyć się niepowodzeniem z następującymi błędami:

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

W przypadku postępowania zgodnie z artykułem firmy Dell 197106, Integracja Avamar i Data Domain: DD wyświetla się na czerwono w ścieżce rozwiązania Avamar AUI i/lub interfejsu użytkownika, certyfikaty nie są generowane.

Po sprawdzeniu MCS logs, istnieje wyjątek związany z protokołem SCP.

Cause

Zapoznaj się z 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.

Oznacza to, że protokół SCP jest wyłączony w Data Domain.

Przepływ certyfikatów synchronizacji między Avamar i Data Domain wymaga włączenia SCP, jak pokazano poniżej:

  1. Avamar uruchamia polecenie w Data Domain przy użyciu klucza publicznego Data Domain do uwierzytelniania bez hasła. Pierwszym poleceniem jest wygenerowanie żądania podpisania certyfikatu (CSR) w Data Domain.
  2. Następnie Avamar próbuje skopiować CSR z Data Domain za pomocą SCP, ale nie udaje mu się to, gdy SCP jest wyłączony w Data Domain.
  3. Avamar użyje CSR do podpisania certyfikatu wystawionego dla Data Domain przez główny urząd certyfikacji Avamar. W Data Domain nazywa się to imported-host DDBoost Certyfikaty:

Sprawdzenie interfejsu użytkownika Data Domain pokazuje, że SCP jest wyłączony:
