|
|
.Sh SYNOPSIS
|
|
.Cd "controller tmscp0 at uba? csr 0174500 vector tmscpintr"
|
|
.Cd "tape tms0 at tmscp0 drive 0"
|
|
.Sh DESCRIPTION
|
|
Tape controllers compatible with the
|
|
.Tn DEC
|
|
Tape Mass Storage Control Protocol
|
|
.Pq Tn TMSCP
|
|
architecture
|
|
such as the
|
|
.Tn TU81
|
|
and the
|
|
.Tn TK50
|
|
provide a standard tape drive interface
|
|
as described in
|
|
.Xr mtio 4 .
|
|
The controller communicates with the host through a packet
|
|
oriented protocol.
|
|
Consult the file
|
|
.Aq Pa vax/tmscp.h
|
|
for a detailed
|
|
description of this protocol.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It tmscp controller failed to init.
|
|
The controller initialization procedure failed.
|
|
This probably indicates a hardware problem.
|
|
.Pp
|
|
.It tmscp%d: sa 0%o, state %d.
|
|
(Additional status information given after a hard
|
|
.Tn I/O
|
|
error.)
|
|
The values of the controller status register and the internal
|
|
driver state are printed.
|
|
.Pp
|
|
.It tmscp%d: random interrupt ignored.
|
|
An unexpected interrupt was received (e.g. when no
|
|
.Tn I/O
|
|
was
|
|
pending). The interrupt is ignored.
|
|
.Pp
|
|
.It tmscp%d: interrupt in unknown state %d ignored.
|
|
An interrupt was received when the driver was in an unknown
|
|
internal state. Indicates a hardware problem or a driver bug.
|
|
.Pp
|
|
.It tmscp%d: fatal error (0%o).
|
|
The controller detected a ``fatal error'' in the status returned
|
|
to the host. The contents of the status register are displayed.
|
|
.Pp
|
|
.It OFFLINE.
|
|
(Additional status information given after a hard
|
|
.Tn I/O
|
|
error.)
|
|
A hard
|
|
.Tn I/O
|
|
error occurred because the drive was not on-line.
|
|
.Pp
|
|
.It tmscp%d: hard error
|
|
.It tmscp%d: soft error.
|
|
These errors precede an interpretation of a
|
|
.Tn TMSCP
|
|
error message
|
|
returned by the controller to the host.
|
|
.Tn TMSCP
|
|
errors may be:
|
|
.Pp

|
.Bd -filled -offset indent -compact
|
|
.It controller error, event 0%o.
|
|
.It host memory access error, event 0%o, addr 0%o.
|
|
.It tape transfer error, unit %d, grp 0x%x, event 0%o.
|
|
.It STI error, unit %d, event 0%o.
|
|
.It STI Drive Error Log, unit %d, event 0%o.
|
|
.It STI Formatter Error Log, unit %d, event 0%o.
|
|
.It unknown error, unit %d, format 0%o, event 0%o.
