Cause

Data Domain OS가 Avamar의 mcserver.xml 에 지정되지 않은 새 암호를 사용합니다.

Resolution

Avamar Server에서 실행 중인 백업, 복원 또는 복제가 없어야 합니다.

/usr/local/avamar/var/mc/server_data/prefs/mcserver.xml의 복제본을 만듭니다.

MCS 서비스를 중지합니다.

mcserver.xml에서 다음 항목을 업데이트합니다. 
<entry key="ddr_rest_supported_cipher_suites"
and
<entry key="ssl_ciphers"
두 항목 모두에 다음 암호가 있는지 확인합니다. 
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

MCS 서비스를

시작합니다. 이제 Avamar 백엔드 보고서(DD)가 작동합니다.
