dpt -- DPT EATA SCSI adapter driver SYNOPSIS
dpt* at isa? port ? irq ? dma ? dpt* at eisa? slot ? dpt* at pci? dev ? function ? scsibus* at dpt? DESCRIPTION
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. HARDWARE
The dpt driver provides support for the adapters listed below. Later models are supported by the iop driver. DPT SmartCache III DPT SmartCache IV DPT SmartRAID III DPT SmartRAID IV FILES

None of these messages should be encountered under normal circumstances. It should be noted that the list below is not complete. dpt%d: readcfg failed - see dpt(4) 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. dpt%d: spurious intr A spurious interrupt was received from the HBA. dpt%d: bogus status (returned CCB id NNNN) A corrupt or incomplete status packet was received from the HBA.

The dpt driver first appeared in NetBSD 1.4.2. BUGS
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. BSD

asr -- driver for Adaptec I2O based SCSI/ATA host bus adapters SYNOPSIS
device asr DESCRIPTION
The Adaptec asr driver provides access to disks and disk arrays controlled by I2O based host bus adapters and SmartRAID SCSI RAID adapters through the standard SCSI disk da(4) interface. The supported adapters provide 64 bit PCI, Compact PCI, Zero Channel PCI, and up to four channels of Ultra2, Ultra 160, or Ultra320 SCSI, or two channels of 1GB Fibre. All support RAID-0, RAID-1, RAID-10, RAID-5 and RAID-50 arrays. All SCSI target types are supported. For the ATA based controllers, one IDE drive per channel is supported. Hot-swapping of IDE drives is not supported at this time. All host bus adapters must be configured before they can be used with any operating system. Please contact Adaptec directly to obtain the latest information on configuration utilities for the adapters. Currently there are both a Motif based GUI configuration utility and a CLI based configuration utility available from the Adaptec Web site. The cards and arrays can also be configured via the BIOS based configura- tion tool (SMOR). HARDWARE
The adapters currently supported by the asr driver include the following: o Adaptec Zero-Channel SCSI RAID 2000S, 2005S, 2010S, 2015S o Adaptec SCSI RAID 2100S, 2110S o Adaptec ATA-100 RAID 2400A o Adaptec SCSI RAID 3200S, 3210S o Adaptec SCSI RAID 3400S, 3410S o Adaptec SmartRAID PM1554 o Adaptec SmartRAID PM1564 o Adaptec SmartRAID PM2554 o Adaptec SmartRAID PM2564 o Adaptec SmartRAID PM2664 o Adaptec SmartRAID PM2754 o Adaptec SmartRAID PM2865 o Adaptec SmartRAID PM3754 o Adaptec SmartRAID PM3755U2B / SmartRAID V Millennium o Adaptec SmartRAID PM3757 o DEC KZPCC-AC (LVD 1-ch, 4MB or 16MB cache), DEC KZPCC-CE (LVD 3-ch, 64MB cache), DEC KZPCC-XC (LVD 1-ch, 16MB cache), DEC KZPCC-XE (LVD 3-ch, 64MB cache) -- rebadged SmartRAID V Millennium FILES
/dev/asr* Adaptec SCSI RAID control nodes NOTES
The ATA based controllers present their devices as SCSI-like devices via CAM. For IDE drives attached to these cards, a subset of standard SCSI commands and mode pages are understood via translation performed in the card's firmware. SEE ALSO
The asr (Adaptec SCSI RAID) driver first appeared as the dpti2o driver under BSDi BSD/OS 3.2, then under FreeBSD 2.2.8 and was ported over to the CAM layer represented in 4.0. AUTHORS
