19.Sh DESCRIPTION
20The
21.Tn TM-11 Ns / Tn TE-10
22combination provides a standard tape drive
23interface as described in
24.Xr mtio 4 .
25Hardware implementing this on the
26.Tn VAX
27is typified by the Emulex
28.Tn TC-11
29controller operating with a Kennedy model 9300 tape transport,
30providing 800 and 1600
31.Tn BPI operation at 125
32.Tn IPS .
33.Sh DIAGNOSTICS
34.Bl -diag
35.It te%d: no write ring.
36An attempt was made to write on the tape drive
37when no write ring was present; this message is written on the terminal of
38the user who tried to access the tape.
39.Pp
40.It te%d: not online.
41An attempt was made to access the tape while it
42was offline; this message is written on the terminal of the user
43who tried to access the tape.
44.Pp
45.It te%d: can't change density in mid-tape.
46An attempt was made to write
47on a tape at a different density than is already recorded on the tape.
48This message is written on the terminal of the user who tried to switch
49the density.
50.Pp
51.It te%d: hard error bn%d er=%b.
52A tape error occurred
53at block
54.Em bn ;
55the tm error register is
56printed in octal with the bits symbolically decoded.  Any error is
57fatal on non-raw tape; when possible the driver will have retried
58the operation which failed several times before reporting the error.
59.Pp
60.It te%d: lost interrupt.
61A tape operation did not complete
62within a reasonable time, most likely because the tape was taken
63off-line during rewind or lost vacuum.  The controller should, but does not,
64give an interrupt in these cases.  The device will be made available
65again after this message, but any current open reference to the device
66will return an error as the operation in progress aborts.
