SYNOPSIS

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


.Cd device pci
.Cd device scbus
.Cd 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 controllers, 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 operation 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 correct 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; initialisation 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 controller. 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.
