AMR(4)		       FreeBSD Kernel Interfaces Manual			AMR(4)

NAME
     amr -- MegaRAID SCSI/ATA/SATA RAID	driver

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

	   device pci
	   device scbus
	   device amr

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

	   amr_load="YES"

DESCRIPTION
     The amr driver provides support for LSI Logic MegaRAID SCSI, ATA and SATA
     RAID controllers and legacy American Megatrends MegaRAID SCSI RAID	con-
     trollers, including models	relabeled and sold by Dell and Hewlett-
     Packard.

     LSI MegaRAID SAS controllers are supported	by mfi(4) and will not work
     with this driver.

DIAGNOSTICS
   Driver initialisation/shutdown phase
     amr%d: memory window not available
     amr%d: I/O	window not available

     The PCI BIOS did not allocate resources necessary for the correct opera-
     tion of the controller.  The driver cannot	attach to this controller.

     amr%d: busmaster bit not set, enabling

     The PCI BIOS did not enable busmaster DMA,	which is required for the cor-
     rect operation of the controller.	The driver has enabled this bit	and
     initialisation will proceed.

     amr%d: can't allocate register window
     amr%d: can't allocate interrupt
     amr%d: can't set up interrupt
     amr%d: can't allocate parent DMA tag
     amr%d: can't allocate buffer DMA tag
     amr%d: can't allocate scatter/gather DMA tag
     amr%d: can't allocate s/g table
     amr%d: can't allocate mailbox tag
     amr%d: can't allocate mailbox memory

     A resource	allocation error occurred while	initialising the driver; ini-
     tialisation has failed and	the driver will	not attach to this controller.

     amr%d: can't obtain configuration data from controller
     amr%d: can't obtain product data from controller

     The driver	was unable to obtain vital configuration data from the con-
     troller.  Initialisation has failed and the driver	will not attach	to
     this controller.

     amr%d: can't establish configuration hook
     amr%d: can't scan controller for drives

     The scan for logical drives managed by the	controller failed.  No drives
     will be attached.

     amr%d: device_add_child failed
     amr%d: bus_generic_attach returned	%d

     Creation of the logical drive instances failed; attachment	of one or more
     logical drives may	have been aborted.

     amr%d: flushing cache...

     The controller cache is being flushed prior to shutdown or	detach.

   Operational diagnostics
     amr%d: I/O	beyond end of unit (%u,%d > %u)

     A partitioning error or disk corruption has caused	an I/O request beyond
     the end of	the logical drive.  This may also occur	if FlexRAID Virtual
     Sizing is enabled and an I/O operation is attempted on a portion of the
     virtual drive beyond the actual capacity available.

     amr%d: polled command timeout

     An	initialisation command timed out.  The initialisation process may fail
     as	a result.

     amr%d: bad	slot %d	completed

     The controller reported completion	of a command that the driver did not
     issue.  This may result in	data corruption, and suggests a	hardware or
     firmware problem with the system or controller.

     amr%d: I/O	error -	%x

     An	I/O error has occurred.
