|
|
.Sh DESCRIPTION
|
|
NOTE: This driver has not been ported from
|
|
.Bx 4.4
|
|
yet.
|
|
.Pp
|
|
The
|
|
.Nm hk
|
|
driver
|
|
is a typical block-device disk driver; block device
|
|
.Tn I/O
|
|
is
|
|
described in
|
|
.Xr physio 4 .
|
|
.Pp
|
|
The script
|
|
.Xr MAKEDEV 8
|
|
should be used to create the special files; if a special file
|
|
needs to be created by hand consult
|
|
.Xr mknod 8 .
|
|
.Sh DISK SUPPORT
|
|
Special file names begin with
|
|
.Sq Li hk
|
|
and
|
|
.Sq Li rhk
|
|
for the block and character files respectively. The second
|
|
component of the name, a drive unit number in the range of zero to
|
|
seven, is represented by a
|
|
.Sq Li ?
|
|
in the disk layouts below. The last component is the file system partition
|
|
which is designated
|
|
by a letter from
|
|
.Sq Li a
|
|
to
|
|
.Sq Li h .
|
|
and
|
|
corresponds to a minor device number set: zero to seven,
|
|
eight to 15, 16 to 23 and so forth for drive zero, drive two and drive
|
|
three respectively.
|
|
The location and size (in sectors) of the
|
|
partitions for the
|
|
.Tn RK06
|
|
and
|
|
.Tn RK07
|
|
drives are as follows:

.El

.Pp
|
|
On a dual
|
|
.Tn RK-07
|
|
system
|
|
partition hk?a is used
|
|
for the root for one drive
|
|
and partition hk?g for the /usr file system.
|
|
If large jobs are to be run using
|
|
hk?b on both drives as swap area provides a 10Mbyte paging area.
|
|
Otherwise
|
|
partition hk?c on the other drive
|
|
is used as a single large file system.

.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "hk%d%c: hard error %sing fsbn %d[-%d] cs2=%b ds=%b er=%b."
|
|
An unrecoverable error occurred during transfer of the specified
|
|
filesystem block number(s),
|
|
which are logical block numbers on the indicated partition.
|
|
The contents of the cs2, ds and er registers are printed
|
|
in octal and symbolically with bits decoded.
|
|
The error was either unrecoverable, or a large number of retry attempts
|
|
(including offset positioning and drive recalibration) could not
|
|
recover the error.
|
|
.Pp
|
|
.It rk%d: write locked.
|
|
The write protect switch was set on the drive
|
|
when a write was attempted. The write operation is not recoverable.
|
|
.Pp
|
|
.It rk%d: not ready.
|
|
The drive was spun down or off line when it was
|
|
accessed. The i/o operation is not recoverable.
|
|
.Pp
|
|
.It rk%d: not ready (came back!).
|
|
The drive was not ready, but after
|
|
printing the message about being not ready (which takes a fraction
|
|
of a second) was ready. The operation is recovered if no further
|
|
errors occur.
|
|
.Pp
|
|
.It rk%d%c: soft ecc reading fsbn %d[-%d].
|
|
A recoverable
|
|
.Tn ECC
|
|
error occurred on the
|
|
specified sector(s) in the specified disk partition.
|
|
This happens normally
|
|
a few times a week. If it happens more frequently than
|
|
this the sectors where the errors are occurring should be checked to see
|
|
if certain cylinders on the pack, spots on the carriage of the drive
|
|
or heads are indicated.
|
|
.Pp
|
|
.It hk%d: lost interrupt.
|
|
A timer watching the controller detected
|
|
no interrupt for an extended period while an operation was outstanding.
|
|
This indicates a hardware or software failure. There is currently a
|
|
hardware/software problem with spinning down drives while they are
|
|
being accessed which causes this error to occur.
|
|
The error causes a
|
|
.Tn UNIBUS
|
|
reset, and retry of the pending operations.
|
|
If the controller continues to lose interrupts, this error will recur
|
|
a few seconds later.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver appeared in
|
|
.Bx 4.1 .
|
|
.Sh BUGS
|
|
The
|
|
.Xr write 2
|
|
function
|
|
scribbles on the tail of incomplete blocks.
|
|
.Pp
|
|
.Tn DEC Ns -standard
|
|
error logging should be supported.
|
|
.Pp
|
|
A program to analyze the logged error information (even in its
|
|
present reduced form) is needed.
|
|
.Pp
|
|
The partition tables for the file systems should be read off of each
|
|
pack, as they are never quite what any single installation would prefer,
|
|
and this would make packs more portable.
|
|
.Pp
|
|
The
|
|
.Tn RK07
|
|
g partition size in rk.c disagrees with that in
|
|
.Pa /etc/disktab .
