     amr -- MegaRAID SCSI/ATA/SATA RAID	driver

     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):


     The amr driver is not present in FreeBSD 14.0.

     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-

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

     Controllers supported by the amr driver include:

   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.

     cd(4), da(4), mfi(4), sa(4), scsi(4)
