NetWorker: Bandåtgärder misslyckas med felet: read open error: kommandot har slutförts (enhetsstatus är MEDIA LOAD OR MATUDECT FAILED) 

Summary: Under bandetikettering eller monteringsåtgärder i NetWorker kan processen misslyckas med felmeddelandet: Read open-fel: kommandot har slutförts (enhetens status är MEDIA LOAD OR EJECT FAILED). Detta indikerar ett problem med att bandenheten sätter i eller matar ut mediet, ofta orsakat av maskinvaru- eller bandmedieproblem. ...

(Investigate bad media or hardware)
  • Operativsystemsloggar rapporterar varningar relaterade till medieladdning eller utmatningsfel på bandenheten, till exempel:
    NetWorker media: (warning) rd=dcp-nwsn1.rnp.local:\\.\Tape4 opening: MEDIA LOAD OR EJECT FAILED

Cause

Som felet antyder, problem med hårdvara (bandenhet) eller bandmedia.

Resolution

Kontrollera om problemet ligger i en specifik bandenhet eller kontrollsökväg genom att byta enhet. Maskinvaruleverantören kan ge bättre hjälp om hur du hanterar den här situationen.
