NAME

ips - IBM/Adaptec ServeRAID controller driver

SYNOPSIS

device scbus
device ips

DESCRIPTION

The ips driver claims to support the IBM (now Adaptec)

ServeRAID series
SCSI controller cards.

These cards come with a built in configuration utility

stored in the
firmware known as the ISPR. This utility is accessed with

the <Ctrl+I>
key combination during the initial card POST.

It is highly recommended that this utility be used to con

figure the card
before attempting to diagnose the below error messages.

In some cases, the ips driver can have difficulties attach

ing during the
system initialization period. To avoid these difficulties,

set the
hw.ips.0.disable tunable to 1. It will prevent the driver

from attaching.

HARDWARE

Controllers supported by the ips driver include:

+o IBM ServeRAID 3H
+o ServeRAID 4L/4M/4H
+o ServeRAID Series 5
+o ServeRAID 6i/6M

DIAGNOSTICS

Several error codes may be shown when the card initializes

the IBM ISPR
utility and are independent of FreeBSD.

ips%d: failed to get adapter configuration data from device ips%d: failed to get drive configuration data from device

Unable to obtain adapter or drive configuration.

ips%d iobuf error

A buffer input/output error has occurred. [ENXIO]

General adapter errors:

Attaching bus failed

WARNING: command timeout. Adapter is in toaster mode,

resetting

AIEE! adapter reset failed, giving up and going home! Have a

nice day

An error occurred while attempting to reset the adapter.

unable to get adapter configuration unable to get drive configuration

There was an error while checking the adapter.

device is disabled

The adapter is disabled.

resource allocation failed irq allocation failed
irq setup failed

Error messages due to DMA:

ERROR: unable to get a command! can't sync cache! ERROR: cache sync command failed! ERROR: unable to get a command! can't sync cache! ERROR: etable command failed!

COMPATIBILITY

Unlike many of the other SCSI devices in FreeBSD, the ips

driver does not
use the cam(4) SCSI subsystem.
