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 ar

rays 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 per

formed in the
card's firmware.

HISTORY

The asr (Adaptec SCSI RAID) driver first appeared as the dp

ti2o 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.
