A separate connection must be opened for each Tape Coordinator. Because the Tape Coordinator must run in the foreground, the connection on which the butc command is issued is unavailable for subsequent commands. The Tape Coordinator window must remain open as long as the Tape Coordinator is running. The level of detail to which each operation is described depends on the operation. In the log and error file names, is the device name of the tape drive with which the Tape Coordinator is associated.
Comparable information is written to both the log and error files.
For example, if backup dump is used to back up a number of volumes, the log file lists both the names of volumes that were successfully dumped and the names of volumes that, for some reason, were omitted from the dump. In the same instance, the error file lists the names of only those volumes omitted from the dump. You can eliminate this initial query, to speed backup and increase the level of backup automation, by running the butc process with the -noautoquery flag. Of course for this feature to work properly, you must place the appropriate tape in the drive prior to the execution of any of the previously mentioned backup commands. You can abort any backup operation involving a tape, prior to inserting a tape and pressing Return, by typing an a and pressing Return at the tape insertion prompt.
