Cause

Het Data Domain-besturingssysteem gebruikt nieuwe versleutelingen die niet zijn opgegeven in de mcserver.xml in Avamar.

Resolution

Er mogen geen back-ups, herstelbewerkingen of replicaties op de Avamar Server worden uitgevoerd.

Maak een kopie van de /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml.

Stop de MCS-service.

Werk de volgende vermeldingen in de mcserver.xml bij: 
<entry key="ddr_rest_supported_cipher_suites"
and
<entry key="ssl_ciphers"
Zorg ervoor dat de volgende cijfers in beide vermeldingen aanwezig zijn: 
TLS_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384

De MCS-service

starten Avamar Backend-rapport (DD) zou nu moeten werken.
