TL_device_name

Purpose

Traces Tape Coordinator operations and logs errors

Description

The TL_device_name file logs the actions performed by the Backup System Tape Coordinator (butc process) 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 /usr/afs/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 /usr/afs/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.
