NAME

       ips — IBM/Adaptec ServeRAID controller driver

SYNOPSIS

       To compile this driver into the kernel, place the following lines in your kernel configuration file:

             device pci
             device scbus
             device ips

       Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

             ips_load="YES"

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
       •   ServeRAID 7t/7k/7M

       Newer ServeRAID controllers are supported by the aac(4) or mfi(4) driver.

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:
       failed to initialize command buffers
       no mem for command slots!

       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.
