     ips -- IBM/Adaptec	ServeRAID controller driver

     device scbus
     device ips

     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 attach-

     Controllers supported by the ips driver include:

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

     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!

     Unlike many of the	other SCSI devices in FreeBSD, the ips driver does not
     use the cam(4) SCSI subsystem.

     ch(4), da(4), sysctl(8)

     The ips driver was	written	by David Jefferys and Scott Long
