NAME

     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).

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.

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.
