Symptoms

Les sauvegardes BMR peuvent échouer avec l’erreur suivante :

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

Si vous suivez l’article Dell 197106, Intégration d’Avamar et de Data Domain : DD s’affiche en rouge dans l’AUI Avamar et/ou le chemin de résolution de l’interface utilisateur, les certificats ne sont pas générés.

Lors de la vérification de l’option MCS logs, il existe une exception liée au protocole SCP.

Cause

Passez en revue la 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.

Cela indique que le protocole SCP est désactivé sur Data Domain.

Le flux de synchronisation des certificats entre Avamar et Data Domain nécessite l’activation de SCP, comme indiqué ci-dessous :

  1. Avamar exécute une commande sur Data Domain à l’aide de la clé publique Data Domain pour l’authentification sans mot de passe. La première commande consiste à générer une demande de signature de certificat (CSR) sur Data Domain.
  2. Avamar tente ensuite de copier la CSR à partir de Data Domain à l’aide de SCP, mais n’y parvient pas lorsque SCP est désactivé sur Data Domain.
  3. Avamar utilise la CSR pour signer un certificat délivré à Data Domain par l’autorité de certification racine Avamar. Sur Data Domain, on l’appelle imported-host DDBoost certificat.

La vérification de l’interface utilisateur Data Domain indique que SCP est désactivé :

Resolution

Activez SCP dans l’interface

Web de Data Domain À partir de Administration > Access > Services > Check SCP > Configure > Check Allow SCP.
