.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Tn TM-11 Ns / Tn TE-10
|
||
|
|
combination provides a standard tape drive
|
||
|
|
interface as described in
|
||
|
|
.Xr mtio 4 .
|
||
|
|
Hardware implementing this on the
|
||
|
|
.Tn VAX
|
||
|
|
is typified by the Emulex
|
||
|
|
.Tn TC-11
|
||
|
|
controller operating with a Kennedy model 9300 tape transport,
|
||
|
|
providing 800 and 1600
|
||
|
|
.Tn BPI operation at 125

.Sh DIAGNOSTICS
|

|
|
.Bl -diag
|
||
|
|
.It te%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 te%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 te%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.
|
||
|
|
.Pp
|
||
|
|
.It te%d: hard error bn%d er=%b.
|
||
|
|
A tape error occurred
|
||
|
|
at block
|
||
|
|
.Em bn ;
|
||
|
|
the tm error register is
|
||
|
|
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.
|
||
|
|
.Pp
|
||
|
|
.It te%d: lost interrupt.
|
||
|
|
A tape operation did not complete
|
||
|
|
within a reasonable time, most likely because the tape was taken
|
||
|
|
off-line during rewind or lost vacuum. The controller should, but does not,
|
||
|
|
give an interrupt in these cases. The device will be made available
|
||
|
|
again after this message, but any current open reference to the device
|
||
|
|
will return an error as the operation in progress aborts.
