RMAN-03009: failure of backup command on dev_0 channel at 06/15/2011 15:09:47

結論是...
你的Data Protector 無法控制 MSL6000 , 可能的问题有
1) 硬件问题 ( MSL6000 ? SCSI HBA ? SCSI cable ? SCSI terminator ? FC HBA ? FC cable ? SAN Switch ? ) , 請檢查
2) DP 設定 Media & Device 有問題了 ( 試試看 , 重新 Add Device )
3) MA version 高於 CM version ? 請檢查
4) MSL6000 driver version 有問題 ? 請檢查 , 更新到適當的版本
5) MSL6000 Firmware 有問題 ? 請檢查
6) SCSI HBA 的 Firmware or driver 有問題? 請檢查
7) FC HBA 的 Firmware or driver 有問題? 請檢查

請試試看.
