Transfer scenes from AVHRR archive tapes to the silo.
Transfer multiple scenes from archive tape to the silo. Multiple tapes may be processed using a tape stacker.
- INFILE
- Input file. The name of the file containing scenes to load. See user note 3 for file format.
- NTAPES(14)
- Number of tapes. The number of tapes loaded in the automatic tape stacker on DRIVE.
- DRIVE(--)
- Tape drive. The name of the device on which the tape has already been mounted. If NULL, a mount request will be sent to the operator.
- COPYFLG
- Copy flag. Flag indicating whether to copy the scene unconditionally, to copy only if the file doesn't already exist on silo, or to delete files on silo before copying.
UCOPY - Unconditional copy CCOPY - Conditional copy DCOPY - Delete before copy
Tape drive 4 has been loaded with 5 tapes. The list of scenes and their corresponding tapeids and time stamps are in the file "loadsilo.list". If scenes already exist in the UCFM with the same 16-digit scene id as those in the list, they will be deleted.
Since NTAPES has not been specified, it is assumed that 1 tape is to be processed. Since a tape drive has not been specified, a prompt to mount a tape will be issued. The scenes contained in the process list will be unconditionally copied to UCFM.
Tape drive 4 has been loaded with 5 tapes. The list of scenes and their corresponding tapeids and time stamps are in the file "loadsilo.list". If individual scenes already exist in the UCFM, those scenes will not be read from tape nor copied to the UCFM.
If the copy flag is either CCOPY or DCOPY, the UCFM is checked for existance of scenes that match the 16-digit scene id of those listed in the input file. The scenes are either deleted from UCFM or edited from the input list.
A working directory is created to which scenes will be placed when read from tape. A loadsilo daemon is started that will look in the working directory and copy any scene found to its appropriate location in the UCFM. LOADLIST is then called to read files found in the input list and place them in the working directory. Once LOADLIST has completed and all files in the working directory have been processed, the loadsilo_daemon is stopped and the directory removed.
The working directory was not empty and could not be removed. Check for errors from the LOADSILO_DAEMON. The files remaining may be manually moved to UCFM and the working directory removed.
An error determining the name of the stop file or the existence of the stop file was encountered. Contact the system administrator.
An error occurred retrieving sceneids, tapeids, or time stamps from the input list file. Check that the input file exists and that is's in the proper format.
An error occurred while finding files on the UCFM. Contact the system administrator.
An error occurred trying to create a working directory. Check that the user has permission to write to the $ADAPSPROD directory.
An error occurred starting the loadsilo_daemon. Contact the system administrator.
A fatal error was encountered. The message displayed preceding this message is the error that was encountered. Processing terminates.

The first line is a comment line and may be followed by any number of lines containing the tapeid, sceneid, time stamp and process flag. The process flag must be 'N' for the file to be copied.
