=head1 NAME butc_logs - Message logs from the Tape Coordinator process =head1 DESCRIPTION The Backup System Tape Coordinator (B) process generates two log files per device, one for error messages and one for actions. =head2 Error Message Log The F> file logs error messages generated by the Backup System Tape Coordinator that controls the tape device or backup data file indicated by I. As the Tape Coordinator initializes, it creates the file in ASCII format in the F directory. If there is an existing file, the Tape Coordinator renames it to F.old>>, overwriting the existing F.old>> file if it exists. For a tape device, the Tape Coordinator derives the variable I portion of the filename from the device pathname listed in the local F file, by stripping off the initial C string and replacing any other slashes in the name with underscores. For example, the filename for a device called F is F. Similarly, for a backup data file the Tape Coordinator strips off the initial slash (C) and replaces any other slashes in the name with underscores. For example, the filename for a backup data file called F is F. The messages in the file describe the error and warning conditions the Tape Coordinator encounters as it operates. For instance, a message can list the volumes that are inaccessible during a dump operation, or warn that the Tape Coordinator is overwriting a tape or backup data file. The messages also appear in the F> file, which traces most of the Tape Coordinator's actions. =head2 Action Log The F> file logs the actions performed by the Backup System Tape Coordinator that controls the tape device or backup data file indicated by I. It also records the same error and warning messages written to the F> file. As the Tape Coordinator initializes, it creates the file in ASCII format in the F directory. If there is an existing file, the Tape Coordinator renames it to F.old>, overwriting the existing F.old> file if it exists. For a tape device, the Tape Coordinator derives the variable I portion of the filename from the device pathname listed in the local F file, by stripping off the initial C string and replacing any other slashes in the name with underscores. For example, the filename for a device called F is F.

For example, the filename for a backup data file called F is F. =head1 SEE ALSO L, L =head1 COPYRIGHT IBM Corporation 2000. All Rights Reserved.
