The dpt
driver provides support for third
and fourth generation DPT SCSI controllers. All communication with the
controllers is conducted via the EATA (Enhanced AT Bus Attachment)
protocol.
DPT adapters examine and interpret all 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.
The dpt
driver provides support for the
adapters listed below. Later models are supported by the
iop
driver.
None of these messages should be encountered under normal circumstances. It should be noted that the list below is not complete.
cd(4), ch(4), dpti(4), intro(4), iop(4), scsi(4), sd(4), st(4)
The sysutils/dptutil package.
CAM committee standard CAM/89-004 - the EATA (Enhanced AT Bus Attachment) protocol.
The dpt
driver first appeared in
NetBSD 1.4.2.
EATA adapters other than listed may function correctly with the
dpt
driver, however a definitive list is not
available.
Older boards that do not support scatter-gather I/O or DMA are not supported.
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.
