driver provides access to SCSI disks
|
|
|
|
|
and disk arrays controlled by I2O based host bus adapters and
|
|
|
|
|
SmartRAID SCSI RAID adapters through the standard SCSI disk

interface.
|

The adapters currently supported include the following RAID adapters:

Some of the adapters provide 64 bit PCI,
|
|
|
|
|
Compact PCI,
|
|
|
|
|
ACPI and up to four channels of Ultra 160 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.
|
|
|
|
|
.Pp
|
|
|
|
|
The PCI adapters automatically configure
|
|
|
|
|
using the configuration mechanism of the bus they are on.
|
|
|
|
|
With PCI adapters
|
|
|
|
|
the IRQ sometimes has to be assigned from a BIOS configuration menu
|
|
|
|
|
(some BIOS's do this automatically).
|
|
|
|
|
.Pp
|
|
|
|
|
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 GUI Motif based configuration utility
|
|
|
|
|
and a CLI based configuration utility available from the Adaptec Web site.
|
|
|
|
|
Note that in the absence of a native BSD/OS version
|
|
|
|
|
of the configuration utilities
|
|
|
|
|
does not mean one can not configure the devices via the BIOS
|
|
|
|
|
based configuration tool Storage Manager on ROM (SMOR).
