Dleting a Device in AIX 4.3

The 'device in use' error comes from the fact that there is a process running which has an open/active file descriptor associated with the device. You must determine the process(es) which is(are) associated with the device and kill it(them).
If the device is a tty then you have to determine which tty is in use (mouse, modems, console, logins, etc) and make sure when you kill the process that you are not killing the shell you are working in. For example, if you are at a console and logged in to the system, you cannot kill that tty. If you do, you will be kicked off, because your shell process (associated with the tty) will die.
Enjoy the detective work! It not too hard of a detective-problem and should be rewarding finding out which TTYs are associated with what process

TTY(4) Linux Programmer's Manual TTY(4) NAME
tty - controlling terminal DESCRIPTION
The file /dev/tty is a character file with major number 5 and minor number 0, usually of mode 0666 and owner.group root.tty. It is a syn- onym for the controlling terminal of a process, if any. In addition to the ioctl(2) requests supported by the device that tty refers to, the ioctl(2) request TIOCNOTTY is supported. TIOCNOTTY Detach the calling process from its controlling terminal. If the process is the session leader, then SIGHUP and SIGCONT signals are sent to the foreground process group and all processes in the current session lose their controlling tty. This ioctl(2) call works only on file descriptors connected to /dev/tty. It is used by daemon processes when they are invoked by a user at a terminal. The process attempts to open /dev/tty. If the open succeeds, it detaches itself from the terminal by using TIOCNOTTY, while if the open fails, it is obviously not attached to a terminal and does not need to detach itself. FILES
