45 | .Sh DESCRIPTION | |
46 | The | |
47 | .Tn TM-11 Ns / Tn TE-10 | |
48 | combination provides a standard tape drive | |
be57b539 | 49 | interface as described in |
9903e566 CL |
50 | .Xr mtio 4 . |
51 | Hardware implementing this on the | |
52 | .Tn VAX | |
53 | is typified by the Emulex | |
54 | .Tn TC-11 | |
be57b539 | 55 | controller operating with a Kennedy model 9300 tape transport, |
9903e566 CL |
56 | providing 800 and 1600 |
57 | .Tn BPI operation at 125 | |
58 | .Tn IPS . | |
59 | .Sh DIAGNOSTICS | |
60 | .Bl -diag | |
61 | .It te%d: no write ring. | |
62 | An attempt was made to write on the tape drive | |
be57b539 KM |
63 | when no write ring was present; this message is written on the terminal of |
64 | the user who tried to access the tape. | |
9903e566 CL |
65 | .Pp |
66 | .It te%d: not online. | |
67 | An attempt was made to access the tape while it | |
be57b539 KM |
68 | was offline; this message is written on the terminal of the user |
69 | who tried to access the tape. | |
9903e566 CL |
70 | .Pp |
71 | .It te%d: can't change density in mid-tape. | |
72 | An attempt was made to write | |
be57b539 KM |
73 | on a tape at a different density than is already recorded on the tape. |
74 | This message is written on the terminal of the user who tried to switch | |
75 | the density. | |
9903e566 CL |
76 | .Pp |
77 | .It te%d: hard error bn%d er=%b. | |
78 | A tape error occurred | |
79 | at block | |
80 | .Em bn ; | |
81 | the tm error register is | |
be57b539 KM |
82 | printed in octal with the bits symbolically decoded. Any error is |
83 | fatal on non-raw tape; when possible the driver will have retried | |
84 | the operation which failed several times before reporting the error. | |
9903e566 CL |
85 | .Pp |
86 | .It te%d: lost interrupt. | |
87 | A tape operation did not complete | |
be57b539 KM |
88 | within a reasonable time, most likely because the tape was taken |
89 | off-line during rewind or lost vacuum. The controller should, but does not, | |
90 | give an interrupt in these cases. The device will be made available | |
91 | again after this message, but any current open reference to the device | |
92 | will return an error as the operation in progress aborts. | |
