* There is no -indent option to .Bd or .Bl, although you would never know that from its frequent use in this tree. There is a "-offset indent" combination that makes sense, and you can certainly say "-width indent". * Also, you can't markup the -width option argument, tho you CAN use a callable macro. So "-width Ar filename" doesn't make sense, but either "-width Ar" or "-width filename" does, as might something like "-width xxfilename" for a little extra space. * There are a lot of needlessly complex hanging tag macros in man4 used to create simple item lists. Those should be simplified one of these days before someone copies and edits yet another man4 page.

|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for third and fourth generation DPT
|
|
.Tn SCSI
|
|
controllers. All communication with the controllers is conducted via the
|
|
EATA (Enhanced AT Bus Attachment) protocol.
|
|
.Pp
|
|
DPT adapters examine and interpret all
|
|
.Tn SCSI
|
|
commands received before passing them to any underlying physical device(s).
|
|
In this way, caching, RAID and other transformations are achieved while
|
|
remaining transparent to the host operating system.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver provides support for the adapters listed below. Later models are
|
|
supported by the
|
|
.Nm iop
|
|
driver.

.Sh DIAGNOSTICS
|
|
None of these messages should be encountered under normal circumstances. It
|
|
should be noted that the list below is not complete.

.Bl -tag -width indent

.It dpt%d: readcfg failed - see dpt(4)
|
|
.br
|
|
The EATA configuration data did not appear upon request. This may be caused
|
|
by older firmware. Generally the solution is to power-cycle the affected
|
|
machine.
|
|

|
|
A spurious interrupt was received from the HBA.

|
.It dpt%d: bogus status (returned CCB id NNNN)
|
|

|
|
A corrupt or incomplete status packet was received from the HBA.

|
.Sh HISTORY
|
|
The
|
|
.Nm dpt
|
|
driver first appeared in
|
|
.Nx 1.4.2 .
|
|
.Sh AUTHORS
|
|
The
|
|
.Nm
|
|
driver was written by
|
|
.An Andrew Doran Aq ad@netbsd.org ,
|
|
based upon the
|
|
.Nm uha
|
|
and
|
|
.Nm bha
|
|
drivers, which are the work of others.
|
|
.Sh BUGS
|
|
EATA adapters other than listed may function correctly with the
|
|
.Nm
|
|
driver, however a definitive list is not available.
|
|
.Pp
|
|
Older firmware may prove problematic. It is recommended that the latest
|
|
available firmware be used. Contact DPT for a firmware update.
|
|
.Pp
|
|
Older boards that do not support scatter-gather I/O or DMA are not supported.
|
|
.Pp
|
|
The number of queued commands available on ISA devices is clamped.
|
|
.Pp
|
|
ECC formatted disk and arrays (i.e. with a sector size of 528 bytes) do not
|
|
work correctly with the PM2041 and certain firmware revisions of the PM3334.
