Ubuntu Manpage: amr — MegaRAID SCSI/ATA/SATA RAID driver

Provided by: freebsd-manpages_12.2-1_all

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
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.
