NetBackup status code: 85

Message: media read error

Explanation: The system device driver returned an I/O error while NetBackup reads from tape or a disk file.

Recommended Action: For additional information, check the following:

NetBackup Problems report to determine the device or media that caused the error
System and error logs for the system (UNIX)
Event Viewer Application and System logs (Windows)
Check for the following:
- A defective or a dirty drive. Clean it or have it repaired (see the tpclean command for cleaning).
- Incorrect drive configuration. Verify the Media and Device Management and system configuration for the drive.
  For example, on UNIX, the drive may be configured for fixed mode when it must be variable mode. More information is available.
  See the NetBackup Device Configuration Guide.
- Defective media. In this case, you may not be able to recover all the data on the media. Use the bpmedia command to set the volume to the FROZEN state so it is not used for future backups.
  See "Frozen media troubleshooting considerations" in the NetBackup Troubleshooting Guide.
- The wrong media type. Verify that the media matches the drive type you use.
