Symptoms
排程的 Hyper-V 備份工作可能會失敗,並出現類似以下的錯誤:
avhypervvss Error <19328>: Unable to forward CTL sub-workorder to remote client [HYPERV-HOST03].avhypervvss Error <19366>: Unable to send sub-workorders to all remote clients.avhypervvss Error <41659>: Backup did not complete successfully.avhypervvss Error <43488>: PAX API 'beginfile:extents' reported error 32.avhypervvss Error <43490>: Failed in begin file C:\ClusterStorage\Volume23\WEBT01\WEBT01-OS.vhdx for incremental backup.avhypervvss Error <43486>: Failed to stream file '00000009\C:\ClusterStorage\Volume23\WEBT01\WEBT01-OS.vhdx...'.avhypervvss Error <43488>: PAX API 'endfile:extents' reported error 32.avhypervvss Error <43473>: Processing workorder in stream mode failed.avhypervvss Error <43475>: Plugin exited with code 536870920: cannot establish connection with server (possible network or DNS failure).
其他錯誤可能會出現在 avtar 和 avagent.log:
avtar Error <41439>: Using invalid token.avtar Error <10542>: DDR server open failed — Invalid API argument.avtar Error <10509>: Problem logging into DDR server.avagent.log:ctl_mcs_send ERROR <0001>: Failed to enqueue the MCS response for federated use case.
手動備份已成功完成。
Cause
此問題通常是因為處理 DDR 權杖要求時,Avamar Utility Node 上的管理主控台服務 (MCS) 延遲所造成。
這些延遲會導致權杖逾時,特別是在 Avamar 和 Data Domain 網格的尖峰備份活動期間。
Resolution
重新排程 Hyper-V 備份工作,在 Avamar 和 Data Domain 系統較不忙碌的非高峰時段執行。
例:
如果大多數備份作業從晚上 8 點開始,請將 Hyper-V 備份安排在晚上 11 點或更晚開始,以避免令牌超時問題。
