Causa

Revise el registro de mcserver:

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

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

Esto muestra que el protocolo SCP está deshabilitado en Data Domain.

El flujo de certificados de sincronización entre Avamar y Data Domain requiere que SCP se habilite como se muestra a continuación:

Avamar ejecuta un comando en Data Domain mediante la clave pública de Data Domain para la autenticación sin contraseña. El primer comando es generar una solicitud de firma de certificado (CSR) en Data Domain.
A continuación, Avamar intenta copiar la CSR de Data Domain mediante SCP, pero no lo hace cuando SCP está deshabilitado en Data Domain.
Avamar usaría la CSR para firmar un certificado emitido a Data Domain por la autoridad de certificación raíz de Avamar. En Data Domain, se denomina certificado "imported-host ddboost".

La comprobación de la interfaz del usuario de Data Domain muestra que SCP está deshabilitado:

Figura 1: La interfaz del usuario de Data Domain muestra que SCP está deshabilitado

Resolução

Habilite SCP en la interfaz

web de Data Domain Desde Administration > Access > Services > Check SCP > Configure > Check Allow SCP.
