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. 67.El 68.Sh SEE ALSO 69.Xr mt 1 , 70.Xr tar 1 , 71.Xr tp 1 , 72.Xr mt 4 , 73.Xr mtio 4 , 74.Xr ht 4 , 75.Xr ts 4 , 76.Xr ut 4 77.Sh HISTORY 78A 79.Nm 80driver appeared in 81.At v6 . 82.Sh BUGS 83May hang if a physical (non-data) error occurs. 84
