The device will be made available 6520683Smckusickagain after this message, but any current open reference to the device 6620683Smckusickwill return an error as the operation in progress aborts. 6747674Scael.El 6847674Scael.Sh SEE ALSO 6947674Scael.Xr mt 1 , 7047674Scael.Xr tar 1 , 7147674Scael.Xr tp 1 , 7247674Scael.Xr mt 4 , 7347674Scael.Xr mtio 4 , 7447674Scael.Xr ht 4 , 7547674Scael.Xr ts 4 , 7647674Scael.Xr ut 4 7747674Scael.Sh HISTORY 7847674ScaelA 7947674Scael.Nm 8047674Scaeldriver appeared in 8147674Scael.At v6 . 8247674Scael.Sh BUGS 8347674ScaelMay hang if a physical (non-data) error occurs. 84
