NAME

       butc_logs - Message logs from the Tape Coordinator process

DESCRIPTION

       The Backup System Tape Coordinator (butc) process generates two log files per device, one for error
       messages and one for actions.

   Error Message Log
       The TE_device_name file logs error messages generated by the Backup System Tape Coordinator that controls
       the tape device or backup data file indicated by device_name.

       As the Tape Coordinator initializes, it creates the file in ASCII format in the /var/lib/openafs/backup
       directory. If there is an existing file, the Tape Coordinator renames it to TE_device_name.old>,
       overwriting the existing TE_device_name.old> file if it exists.

       For a tape device, the Tape Coordinator derives the variable device_name portion of the filename from the
       device pathname listed in the local /var/lib/openafs/backup/tapeconfig file, by stripping off the initial
       "/dev/" string and replacing any other slashes in the name with underscores. For example, the filename
       for a device called /dev/rmt/4m is TE_rmt_4m. Similarly, for a backup data file the Tape Coordinator
       strips off the initial slash ("/") and replaces any other slashes in the name with underscores. For
       example, the filename for a backup data file called /var/tmp/FILE is TE_var_tmp_FILE.

       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
       /var/lib/openafs/backup/TL_device_name file, which traces most of the Tape Coordinator's actions.

   Action Log
       The TL_device_name file logs the actions performed by the Backup System Tape Coordinator that controls
       the tape device or backup data file indicated by device_name. It also records the same error and warning
       messages written to the TE_device_name file.

       As the Tape Coordinator initializes, it creates the file in ASCII format in the /var/lib/openafs/backup
       directory. If there is an existing file, the Tape Coordinator renames it to TL_device_name.old,
       overwriting the existing TL_device_name.old file if it exists.

       For a tape device, the Tape Coordinator derives the variable device_name portion of the filename from the
       device pathname listed in the local /var/lib/openafs/backup/tapeconfig file, by stripping off the initial
       "/dev/" string and replacing any other slashes in the name with underscores. For example, the filename
       for a device called /dev/rmt/4m is TL_rmt_4m. Similarly, for a backup data file the Tape Coordinator
       strips off the initial slash ("/") and replaces any other slashes in the name with underscores. For
       example, the filename for a backup data file called /var/tmp/FILE is TL_var_tmp_FILE.
