|
|
.Sh SYNOPSIS
|
|
.Cd device scbus
|
|
.Cd device ips
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver claims to support the
|
|
.Tn IBM
|
|
(now Adaptec) ServeRAID series
|
|
.Tn SCSI
|
|
controller cards.
|
|
.Pp
|
|
These cards come with a built in configuration utility stored in
|
|
the firmware known as the
|
|
.Tn ISPR .
|
|
This utility is accessed with the
|
|
.Aq Em Ctrl+I
|
|
key combination during the initial card
|
|
.Tn POST .
|
|
.Pp
|
|
It is highly recommended that this utility be used to configure the card
|
|
before attempting to diagnose the below error messages.
|
|
.Pp
|
|
In some cases, the
|
|
.Nm
|
|
driver can have difficulties attaching during
|
|
the system initialization period.
|
|
To avoid these difficulties, set the
|
|
.Va hw.ips.0.disable
|
|
tunable to 1.
|
|
It will prevent the driver from attaching.
|
|
.Sh HARDWARE
|
|
Controllers supported by the
|
|
.Nm
|
|
driver include:
