管理主控台伺服器 (MCS) 記錄 (/usr/local/avamar/var/mc/server_log/mcserver.log*) 中,Avamar 工具節點回報下列例外狀況:

此外,以下DDR_POLLING_FAILURE事件:
WARNING: DDR_POLLING_FAILURE: <event-source NodeID="test-ave-company.com" ProgramName="com.avamar.mc.datadomain.DdrCache" ddr-id="" ddr-name="" gsan-version="" hardware-id="UNKNOWN" source-hardware-id="UNKNOWN"/> ddrCommandFailureCount = 7
使用下列命令時,Data Domain 顯示為空白:
mccli dd show-prop --name=<IP of the Data Domain>
1,30943,Data Domain system does not exist. Cause
已使用 IP 位址新增 Data Domain。
如果發生使用 IP 位址而非完整主機名稱 (FQDN) 新增 Data Domain 的 DNS 相關問題,MCS DNS 快取可能會無法同步。這反過來會在編輯 Data Domain 時引發錯誤。
Avamar Data Domain 整合指南建議不要使用 IP 位址新增 Data Domain。
