NAME

ht − TM-03/TE-16,TU-45,TU-77 MASSBUS magtape interface

SYNOPSIS

master ht0 at mba? drive ? 
tape tu0 at ht0 slave 0

DESCRIPTION

The tm-03/transport combination provides a standard tape drive interface as described in mtio(4). All drives provide both 800 and 1600 bpi; the TE-16 runs at 45 ips, the TU-45 at 75 ips, while the TU-77 runs at 125 ips and autoloads tapes.

DIAGNOSTICS

tu%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. 

tu%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. 

tu%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 density. 

tu%d: hard error bn%d mbsr=%b er=%b ds=%b.   A tape error occurred at block bn; the ht error register and drive status register are 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. 

BUGS

If any non-data error is encountered on non-raw tape, it refuses to do anything more until closed.
