備份完成 (但有例外情況)
NetApp 備份完成後,但出現例外情況,表示存取特定磁碟區時發生問題。
在 avndmp 記錄中觀察到下列錯誤訊息:
2017-06-15 18:18:43 avndmp Error <0000>: [snapup-/vol/list_man_data] Volume: /vol/list_man_data is offline and cannot be accessed. (Log #3) 2017-06-15 18:18:43 avndmp Error <0000>: [snapup-/vol/list_man_data] Nothing to backup. Target list is empty.

Cause
問題的根本原因
此問題的根本原因與 NetApp 卷離線但仍對網路數據管理協定 (NDMP) 可見時的處理方式有關。
有了 NetApp,磁碟區可以離線,但 NDMP 通訊協定可以查看磁碟區。當 Avamar NDMP 瀏覽 NetApp 資料移動者時,會同時傳回線上和離線磁碟區。
當 NDMP 要求離線磁碟區的傾印時,會傳回錯誤,如 avndmp 記錄訊息所示:
2017-06-15 18:18:43 avndmp Error <0000>: [snapup-/vol/list_man_data] Volume: /vol/list_man_data is offline and cannot be accessed. (Log #3) 2017-06-15 18:18:43 avndmp Error <0000>: [snapup-/vol/list_man_data] Nothing to backup. Target list is empty. (Log #3)
導致原因的關鍵因素。
- 磁碟區正在離線,但 NDMP 通訊協定仍可檢視
- Avamar NDMP 瀏覽 NetApp 資料移動者並傳回線上和離線磁碟區
- NDMP 要求離線磁碟區的傾印,並傳回錯誤
Resolution
解決 Avamar NDMP NetApp 備份例外
若要解決 Avamar NDMP NetApp 備份完成,但因離線磁碟區而發生例外的問題,NetApp 系統管理員必須採取特定步驟。
NetApp 管理員必須完全刪除不存在的卷,而不僅僅是將它們脫機。或者,他們可以修改配置,以便 NDMP 通訊協定不會顯示離線卷。
