dpt(7D) Devices dpt(7D) NAME
dpt - DPT ServeRAID IV SCSI host bus adapter and RAID adapter driver DESCRIPTION
The dpt driver is a driver for the DPT (Distributed Processing Technology) family of SmartRAID IV SCSI HBA and RAID adapters. The following HBA adapters are supported: PM2024, PM2044UW, PM2044W, PM2124, PM2124W, PM2144UW, and PM2144W. The following RAID adapters are supported: PM3224, PM3224W, PM3334UW, and PM3334W. PRECONFIGURATION
o DPT PM3224 only: Only EPROM 7A and later versions are supported. o DPT PM2024 and PM2124 only: Only EPROM 6D4 and later versions are supported. o Use adapters with SmartROM version 3.B or later versions only. o Be sure that the controller board is installed in a PCI bus-mastering slot. o Disable PCI parity checking if your firmware version is earlier than version 7A, if your system memory is ECC, or if your system does not check parity. Known Problems and Limitations During system boot, a message may be displayed saying a DPT controller driver cannot be installed. This message indicates that the mother- board installed in your system may contain ECC memory or may not check parity. If you see this message is displayed, disable PCI parity checking. Supported Settings o I/O Address: Auto CONFIGURATION
Auto-configuration code determines whether the adapter is present at the configured address and what types of devices are attached to it. The DPT ServeRAID is primarily used as a disk array (system drive) controller. To configure the attached disk arrays, you must configure the controller (using the configuration utilities provided by the hardware manu- facturer) before you boot the Solaris operating environment. You use the configuration utilities to set RAID levels, stripe parameters, cache mechanisms and perform other functions. For more information, see the user manual supplied with your hardware. FILES

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
da(4) HISTORY
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
The asr driver was kindly donated by Adaptec and is maintained by Mark Salyzyn <mark_salyzyn@adaptec.com>. This manual page was written by Mark Salyzyn and fixed up by Jeroen Ruigrok van der Werven <asmodai@FreeBSD.org>. BSD
