Resolution:
Remove the write protection from the tape by adjusting the write protect notch, or by following the recommended procedure from the media manufacturer on how to disable write protection. If media is intentionally meant to be write protected, either remove the media from the robot or freeze the media in NetBackup (tm) so that it is not available for backup attempts. Media can be frozen and unfrozen using the bpmedia command. For more information on this procedure, please see the NetBackup Commands for Windows Guide.
