IPS(4) MidnightBSD Kernel Interfaces Manual IPS(4)

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

In some cases, the ips driver can have difficulties attaching 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:

IBM ServeRAID 3H

ServeRAID 4L/4M/4H

ServeRAID Series 5

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 

This message is undocumented.

WARNING: command timeout. Adapter is in toaster mode, resetting 

A command timeout has caused the adapter to be reset.

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 when attempting to get configuration information.

Adapter error during initialization. 
adapter initialization failed 

There was an error while attempting to initialize the adapter.

adapter failed config check 
adapter clear failed 

There was an error while checking the adapter.

device is disabled 

The adapter is disabled.

resource allocation failed 
irq allocation failed 
irq setup failed 

The driver was unable to allocate resources for the device.

Error messages due to DMA:
can’t alloc command dma tag 
can’t alloc SG dma tag 
can’t alloc dma tag for statue queue 
dmamap failed 

Failure to map or allocate DMA resources.

Cache, buffer, and command errors:

The ips driver will return [ENOMEM] in such cases.

ERROR: unable to get a command! can’t flush cache! 
ERROR: cache flush command failed! 
ERROR: unable to get a command! can’t update nvram 
ERROR: nvram update command failed! 
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.
