35.Sh NAME
36.Nm tm
37.Nd
38.Tn TM-11 Ns / Ns Tn TE-10
39mag tape device interface
40.Sh SYNOPSIS
41.Sy "controller tm0 at uba? csr 0172520 vector tmintr"
42.Sy "tape te0 at tm0 drive 0"
43.Sh DESCRIPTION
44NOTE: This driver has not been ported from
45.Bx 4.4
46yet.
47.Pp
48The
49.Tn TM-11 Ns / Ns Tn TE-10
50combination provides a standard tape drive
51interface as described in
52.Xr vax/mtio 4 .
53Hardware implementing this on the
54.Tn VAX
55is typified by the Emulex
56.Tn TC-11
57controller operating with a Kennedy model 9300 tape transport,
58providing 800 and 1600
59.Tn BPI operation at 125
60.Tn IPS .
61.Sh DIAGNOSTICS
62.Bl -diag
63.It te%d: no write ring.
64An attempt was made to write on the tape drive
65when no write ring was present; this message is written on the terminal of
66the user who tried to access the tape.
67.It te%d: not online.
68An attempt was made to access the tape while it
69was offline; this message is written on the terminal of the user
70who tried to access the tape.
71.It te%d: can't change density in mid-tape.
72An attempt was made to write
73on a tape at a different density than is already recorded on the tape.
74This message is written on the terminal of the user who tried to switch
75the density.
76.It te%d: hard error bn%d er=%b.
77A tape error occurred
78at block
79.Em bn ;
80the tm error register is
81printed in octal with the bits symbolically decoded.
82Any error is
83fatal on non-raw tape; when possible the driver will have retried
84the operation which failed several times before reporting the error.
85.It te%d: lost interrupt.
86A tape operation did not complete
87within a reasonable time, most likely because the tape was taken
88off-line during rewind or lost vacuum.
89The controller should, but does not, give an interrupt in these cases.
90The device will be made available
91again after this message, but any current open reference to the device
92will return an error as the operation in progress aborts.
