이 문제를 해결하려면 루트 서버 암호를 mcserver.xml 파일을 열고 MCS를 다시 시작합니다. 이렇게 하면 Data Domain SNMP 관리자가 시작되고 Data Domain이 Avamar UI와 MCCLI 모두에 표시됩니다.

• 루트 서버 암호를 일반 텍스트로 입력하십시오. /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml 그리고 다시 암호화합니다.
• 백업 mcserver.xml:

cp -p /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml /usr/local/avamar/var/mc/server_data/prefs/x-mcserver.xml

• 편집 /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml 루트 서버 비밀번호를 rootAP 값에 일반 텍스트로 입력합니다.
