PowerProtect Data Manager는 TSDM(Transparent Snapshot Data Mover) 솔루션으로 vSphere 환경을 보호하는 데 사용됩니다. 과거에는 성공적으로 완료되던 일부 VM 자산 백업이 실패하기 시작했습니다. 장애 세부 정보는 vCenter 작업이 실패하고 TSDM 오류가 표시되며 "DPD 동기화 진행 중"을 나타냅니다. ABV0016 및 ABV0006 세부 정보에는 다음이 표시됩니다.
ABV0016: VM Direct engine 'localhost' is unable to back up the virtual machine 'my-vm-name' on vCenter 'my-vcernter-name' because of a vCenter API issue. The VM Direct engine cannot complete the backup of this virtual machine because of a vCenter API operation did not complete successfully. To troubleshoot this issue: 1) Verify that the vCenter can be reached. 2) If the vCenter is busy, wait for some activities to complete and then retry the operation. 3) Verify that the virtual machine exists on the vCenter.

분리된 vSphere SDM 스냅샷 작업을 지우려면 영향을 받는 VM에서 SDM 기능을 비활성화했다가 다시 활성화해야 합니다. 다음은 영향을 받는 VM에서 SDM을 비활성화하고 활성화하는 몇 가지 방법입니다.
영향을 받는 VM 자산 보호 메커니즘을 변경합니다.
보호 정책에서 영향을 받는 VM을 제거하고 추가합니다.
The PowerProtect Data Manager vmconfig
명령줄 유틸리티를 사용하여 영향을 받는 VM에 대한 SDM 기능 설정을 변경할 수 있습니다.
ssh admin@my-ppdm-name
sudo su
source /opt/emc/vproxy/unit/vproxy.env
cd /opt/emc/vproxy/bin/
vmconfig
대괄호 안의 정보를 대체하여 명령을 실행합니다.
