This error was found in VCS log on an IBM 570 running AIX 5.2, VCS 3.5.
When tried to shutdown/start a resource, this error was logged.
(Background, when shutdown/start a resource - VCS engine calls
shutdown/startup scripts.)

I suspect the error was generated due to root's .profile a line like
stty erase ^

I've changed the .profile as follow:
tty -s && stty erase ^

Haven't have a chance to run startup/shutdown again. Anyone has seen
this error?

The error is logged when an tty-specific ioctl call is performed on a device
that isn't a tty.
stty -a < /dev/ttynn (no error)

stty -a < /dev/null (error logged - not a tty)

The error could be generated from a line in your .profile if there is
something that runs your .profile without you being logged in?
