.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It tu%d: no write ring.
|
|
An attempt was made to write on the tape drive
|
|
when no write ring was present; this message is written on the terminal of
|
|
the user who tried to access the tape.
|
|
.Pp
|
|
.It tu%d: not online.
|
|
An attempt was made to access the tape while it
|
|
was offline; this message is written on the terminal of the user
|
|
who tried to access the tape.
|
|
.Pp
|
|
.It tu%d: can't change density in mid-tape.
|
|
An attempt was made to write
|
|
on a tape at a different density than is already recorded on the tape.
|
|
This message is written on the terminal of the user who tried to switch
|
|
the density.

.It "tu%d: hard error bn%d mbsr=%b er=%b ds=%b."
|
|
A tape error occurred
|
|
at block

|
.Em bn ;
|
|
the ht error register and drive status register are
|
|
printed in octal with the bits symbolically decoded. Any error is
|
|
fatal on non-raw tape; when possible the driver will have retried
|
|
the operation which failed several times before reporting the error.
