NetWorker: Tapebewerkingen mislukken met de fout: read open fout: opdracht voltooid (schijfstatus is MEDIA LADEN OF UITWERPEN MISLUKT) 

• Labeling or mounting tape volumes fail with the error message:
  read open error: command completed successfully (drive status is MEDIA LOAD OR EJECT FAILED)
  
  
• Daemon logs (daemon.raw) geven de volgende waarschuwingen en fouten weer tijdens label- of montagebewerkingen:
  

  NSR info media warning: <device_name> opening: MEDIA LOAD OR EJECT FAILED  
  nsrd NSR info media warning: <device_name> moving: read open error: command completed successfully (drive status is MEDIA LOAD OR EJECT FAILED)  
  nsrd NSR warning Status update: operation 'SNMD_DEVOP_DEACTIVATE', instance '356', on device '<device_name>' has completed abnormally with status 'DEV_OP_ERROR'.

• Controleer de status van het tapestation met behulp van het mt Opdracht geeft datafouten weer, wat wijst op mogelijke hardware- of mediaproblemen:
  
  

  mt -f <device_name> status  
  <device_name>:

  (Investigate bad media or hardware)

• Logboeken van het besturingssysteem melden waarschuwingen met betrekking tot fouten bij het laden of uitwerpen van media op het tapeapparaat, zoals:
  

  NetWorker media: (warning) rd=dcp-nwsn1.rnp.local:\\.\Tape4 opening: MEDIA LOAD OR EJECT FAILED

Zoals de fout doet vermoeden, is er een probleem met de hardware (tapestation) of tapemedia.

Controleer of het probleem te maken heeft met een specifiek tapestation of besturingspad door stations te verwisselen. De hardwareleverancier kan u beter helpen bij het omgaan met deze situatie.
