TM(4) BSD/vax Kernel Interfaces Manual TM(4)NAMEtm — TM-11/ TE-10 magtape device interface

The TM-11/ TE-10 combination provides a standard tape drive interface as
described in mtio(4). Hardware implementing this on the VAX is typified
by the Emulex TC-11 controller operating with a Kennedy model 9300 tape
transport, providing 800 and 1600 BPI operation at 125 IPS.
te%d: no write ring. An attempt was made to write on the tape drive when
no write ring was present; this message is written on the terminal of the
user who tried to access the tape.
te%d: not online. An attempt was made to access the tape while it was
offline; this message is written on the terminal of the user who tried to
access the tape.
te%d: can't change density in mid-tape. An attempt was made to write on
a tape at a different density than is already recorded on the tape. This
message is written on the terminal of the user who tried to switch the
te%d: hard error bn%d er=%b. A tape error occurred at block bn; the tm
error register is printed in octal with the bits symbolically decoded.
Any error is fatal on non-raw tape; when possible the driver will have
retried the operation which failed several times before reporting the
te%d: lost interrupt. A tape operation did not complete within a reason‐
able time, most likely because the tape was taken off-line during rewind
or lost vacuum. The controller should, but does not, give an interrupt
in these cases. The device will be made available again after this mes‐
sage, but any current open reference to the device will return an error
as the operation in progress aborts.

A tm driver appeared in Version 6 AT&T UNIX.
May hang if a physical (non-data) error occurs.
