  12. Duplicate Tape (DUPTAP) command The Duplicate Tape (DUPTAP) command copies the contents of one tape to another tape. You must have two tape drives or a tape media library device with two tape resources to use this command.

Cause . . . . . : The device could not be allocated when trying to open the device file to do the command function. The device may be varied off, in use by another job, or in use by an open file in this job. Recovery . . . : Use the Work with Configuration Status WRKCFGSTS) command specifying the *DEV value for the CFGTYP parameter to verify that the device is varied on and to determine what job is using the device. Try the command again when the device is available.

  14. Tape message(2/2) Message ID . . . . . . . . . : CPF6760 Message . . . . : Device tap01 not ready. Cause . . . . . : -- The tape may not be loaded. -- The tape may have been a cleaning cartridge. -- If the device is a tape media library device, then the cartridge may not have loaded successfully. Recovery . . . : Do one of the following: -- If the device is a reel tape drive, make sure the tape is loaded and the online light is on. -- If the tape device is a 1/4 inch cartridge tape drive, unload and reload the cartridge. -- If the device is a tape media library device and the cartridge was not a cleaning cartridge, attempt the command again. -- If the tape device is a 1/2 inch cartridge tape drive or an 8 millimeter cartridge drive, ensure the tape is loaded and the tape drive is ready. If the problem continues, start problem analysis (ANZPRB command). Technical description . .
