On 4.2BSD when an open(2) is attempted on an offline tape
drive the following message is returned:
tm0: not online
As an example, putting the tape drive offline and executing:
mt status
results in:
tm0: not online
/dev/rmt12: I/O error
The 2nd line seems to be printed by mt(1) if a bad file descriptor is
returned by open(2). This line is printed to stderr and can therefore
be redirected. The 1st line seems to be coming from the tape drive
"driver". Now the question. How can I redirect the 1st message to
"/dev/null"? The typical methods do not work. How is this message
different from other types of screen I/O ( stdout, stderr)?
P.S. I don't have access to the licensed source code (i.e. I'm not
a sys-op).
Thanks for any help,
Mike
