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
       configuration 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.
