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. HARDWARE Controllers supported by the amr driver include: o MegaRAID SATA 150-4 o MegaRAID SATA 150-6 o MegaRAID SATA 300-4X o MegaRAID SATA 300-8X o MegaRAID SCSI 320-1E o MegaRAID SCSI 320-2E o MegaRAID SCSI 320-4E o MegaRAID SCSI 320-0X o MegaRAID SCSI 320-2X o MegaRAID SCSI 320-4X o MegaRAID SCSI 320-0 o MegaRAID SCSI 320-1 o MegaRAID SCSI 320-2 o MegaRAID SCSI 320-4 o MegaRAID Series 418 o MegaRAID i4 133 RAID o MegaRAID Elite 1500 (Series 467) o MegaRAID Elite 1600 (Series 493) o MegaRAID Elite 1650 (Series 4xx) o MegaRAID Enterprise 1200 (Series 428) o MegaRAID Enterprise 1300 (Series 434) o MegaRAID Enterprise 1400 (Series 438) o MegaRAID Enterprise 1500 (Series 467) o MegaRAID Enterprise 1600 (Series 471) o MegaRAID Express 100 (Series 466WS) o MegaRAID Express 200 (Series 466) o MegaRAID Express 300 (Series 490) o MegaRAID Express 500 (Series 475) o Dell PERC o Dell PERC 2/SC o Dell PERC 2/DC o Dell PERC 3/DCL o Dell PERC 3/QC o Dell PERC 4/DC o Dell PERC 4/IM o Dell PERC 4/SC o Dell PERC 4/Di o Dell PERC 4e/DC o Dell PERC 4e/Di o Dell PERC 4e/Si o Dell PERC 4ei o HP NetRAID-1/Si o HP NetRAID-3/Si (D4943A) o HP Embedded NetRAID o Intel RAID Controller SRCS16 o Intel RAID Controller SRCU42X 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.
