tm(4) Unsupported tm(4)Nametm - TM-11/TE-10 magtape interface
Syntax
controller tm0 at uba? csr 0172520 vector tmintr
tape te0 at tm0 drive 0
Description
The tm-11/te-10 combination provides a standard tape drive interface as
described in Hardware implementing this on the VAX is typified by the
Emulex TC-11 controller operating with a Kennedy model 9300 tape trans‐
port, providing 800 and 1600 bpi operation at 125 ips.
Restrictions
If any non-data error is encountered on non-raw tape, it refuses to do
anything more until closed.
Diagnostics
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 mes‐
sage is written on the terminal of the user who tried to access the
tape.
te%d: can't switch 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 density.
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 error.
te%d: lost interrupt.
A tape operation did not complete within a reasonable 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 message, but any current
open reference to the device will return an error as the operation in
progress aborts.
