					AMR (4)                                   BSD 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 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 cor-
      ruption, and suggests a hardware or firmware problem with the system or controller.
      amr%d: I/O error - %x
      An I/O error has occurred.
