45 | .It tu%d: no write ring. | |
46 | An attempt was made to write on the tape drive | |
85423ffc KM |
47 | when no write ring was present; this message is written on the terminal of |
48 | the user who tried to access the tape. | |

50 | .It tu%d: not online. | |
51 | An attempt was made to access the tape while it | |
85423ffc KM |
52 | was offline; this message is written on the terminal of the user |
53 | who tried to access the tape. | |
9903e566 CL |
54 | .Pp |
55 | .It tu%d: can't change density in mid-tape. | |
56 | An attempt was made to write | |
85423ffc KM |
57 | on a tape at a different density than is already recorded on the tape. |
58 | This message is written on the terminal of the user who tried to switch | |
59 | the density. | |

61 | .It "tu%d: hard error bn%d mbsr=%b er=%b ds=%b." | |
62 | A tape error occurred | |
63 | at block | |
64 | .Em bn ; | |
65 | the ht error register and drive status register are | |
85423ffc KM |
66 | printed in octal with the bits symbolically decoded. Any error is |
67 | fatal on non-raw tape; when possible the driver will have retried | |
68 | the operation which failed several times before reporting the error. | |
