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).

asr driver include the

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.
