1 TPCOPY TPCOPY - Tape Copy Program ========================== The TPCOPY program is a very flexible program which copies between a mag-tape and a disk file. The disk file is a specially formatted "container file" which contains the entire image of the tape. The main use of TPCOPY is to duplicate tapes or to convert a tape from one density to another. To use TPCOPY for duplicating tapes, you copy the "master" tape to a container file on disk, then for each duplicate tape, copy the container file out to the tape. To use TPCOPY for changing the density of a tape, read the tape into a temporary container file, change the density setting on the tape drive and then write the container file back out to tape. Then delete the temporary file. 2 TAPE_TO_DISK TPCOPY - Tape to Disk Command Format ==================================== To copy a tape into a "container" file on disk, the command is: $ TPCOPY file=MSA0: where 'file' is the name you want to give to the container file. If you are using TPCOPY to reformat a tape to another density, you can name the file something like TEMP.TPC, so you'll know it's a scratch file if you happen to see it a few days later and you forgot to delete it. If you making a "master", such as a CT*OS Demo Tape image, name the file CTOSDEMO.TPC, or something that will jog your memory as to it's contents. There is no easy way to look at the contents of a container file and determine what is there. 2 DISK_TO_TAPE TPCOPY - Disk to Tape Command Format ==================================== To recreate a tape from a TPCOPY "container" file, the command looks like this: $ TPCOPY MSA0:=file where 'file' is the name of the container file. 2 CHANGE_DENSITY TPCOPY - Changing Tape Density ============================== To use TPCOPY to change the density of a tape, do the following steps: $ ALLOCATE MSA0: $ MOUNT/FOREIGN MSA0: $ TPCOPY TEMP.TPC=MSA0: $ < At this point, go in and change the density on the tape > $ TPCOPY MSA0:=TEMP.TPC $ DELETE TEMP.TPC;* $ DISMOUNT MSA0: $ DEALLOCATE MSA0: That's all there is to it. Try to figure out what each step does.
