Any 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.Pp 86.It te%d: lost interrupt. 87A tape operation did not complete 88within a reasonable time, most likely because the tape was taken 89off-line during rewind or lost vacuum. The controller should, but does not, 90give an interrupt in these cases. The 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. 93.El 94.Sh SEE ALSO 95.Xr mt 1 , 96.Xr tar 1 , 97.Xr tp 1 , 98.Xr mt 4 , 99.Xr mtio 4 , 100.Xr ht 4 , 101.Xr ts 4 , 102.Xr ut 4 103.Sh HISTORY 104A 105.Nm 106driver appeared in 107.At v6 . 108.Sh BUGS 109May hang if a physical (non-data) error occurs. 110
