NetBackup status code: 172
Message: cannot read media header, may not be NetBackup media or is corrupted
Explanation: When you loaded a volume for a backup or restore, the tape manager (bptm), did not find the expected tape header. This error can mean that a robotic device volume is not in the slot number that is in the Media and Device Management volume configuration. It also can mean that a read error (I/O error) occurred.
Recommended Action: Do the following, as appropriate:
If the volume is in a robot that supports bar codes, verify the robot contents by using a robot inventory option.
If the volume was mounted on a nonrobotic drive, verify that the correct volume was mounted and assigned.
Check the NetBackup Problems report. If it shows a fatal read error, try the operation again with another drive, if possible.
If your configuration has multiple servers or HBAs with access to your tape services, make sure that the SCSI Reserve or Release is onfigured correctly. (Most likely, the tape services configuration is an SSO configuration.)
For more information on the storage server, please see the NetBackup Administrator's Guide, Volume II.
