NetBackup status code: 83
Message: media open error
Explanation: The tape manager (bptm) or disk manager (bpdm) did not open the device or file that the backup or restore must use.
Recommended Action: For additional information, check the following:
NetBackup Problems report
Event Viewer Application log (Windows)
System log (UNIX)
Typically, this status code indicates a drive configuration problem that allows more than one process at a time to open the device. On UNIX, the problem may be due one or more of the following:
Two (or more) devices were configured that are the same physical device (for different densities perhaps). Verify that none of the
/devfiles that were used for these devices have the same major or minor numbers.Links exist in the file system that allows users access to the drives.
The configuration for the drives was modified (in the administrator interface or
vm.conf) and the Media Manager device daemon, ltid, was not restarted. Verify the configuration and then start ltid.
On Windows, the problem may be that the Media and Device Management device configuration was modified but the NetBackup Device Manager service was not restarted. Verify the configuration and restart the NetBackup Device Manager service.
On Windows, make sure that the tapes are not write protected.
For detailed troubleshooting information:
Create a debug log directory for bpdm (if the device is disk) or bptm (if the device is tape).
On UNIX, restartltid in the verbose mode by running the following:
/usr/openv/volmgr/bin/ltid -v
Or, add a VERBOSE entry to the
/usr/openv/volmgr/vm.conffile. Create thevm.conffile if necessary.On Windows, to enable verbose logging, add VERBOSE on a line by itself in the
install_path\Volmgr\vm.conffile. Then, stop and restart the NetBackup Device Manager service.Retry the operation and check the resulting debug log files.
On Windows systems, look at the
install_path\NetBackup\db\media\errorslog for a drive that frequently produces errors.On UNIX systems, look at the
/usr/openv/netbackup/db/media/errorslog (which is also included in the/usr/openv/netbackup/bin/support/nbsuscript output) for a drive that frequently produces errors.
