31 .Nd MegaRAID SCSI/ATA/SATA RAID driver
33 To compile this driver into the kernel,
34 place the following lines in your
35 kernel configuration file:
36 .Bd -ragged -offset indent
42 Alternatively, to load the driver as a
43 module at boot time, place the following line in
45 .Bd -literal -offset indent
51 driver provides support for LSI Logic MegaRAID SCSI, ATA and SATA
52 RAID controllers and legacy American Megatrends MegaRAID
53 SCSI RAID controllers, including models relabeled
54 and sold by Dell and Hewlett-Packard.
56 LSI MegaRAID SAS controllers are supported by
58 and will not work with this driver.
60 Controllers supported by the

169 The PCI BIOS did not enable busmaster DMA,
170 which is required for the correct operation of the controller.
171 The driver has enabled this bit and initialisation will proceed.

182 A resource allocation error occurred while initialising the driver;
183 initialisation has failed and the driver will not attach to this controller.
184 .It amr%d: can't obtain configuration data from controller
185 .It amr%d: can't obtain product data from controller
187 The driver was unable to obtain vital configuration data from the controller.
188 Initialisation has failed and the driver will not attach to this controller.
189 .It amr%d: can't establish configuration hook
190 .It amr%d: can't scan controller for drives
192 The scan for logical drives managed by the controller failed.
193 No drives will be attached.
194 .It amr%d: device_add_child failed
195 .It amr%d: bus_generic_attach returned %d
197 Creation of the logical drive instances failed;
198 attachment of one or more logical drives may have been aborted.
199 .It amr%d: flushing cache...
201 The controller cache is being flushed prior to shutdown or detach.

205 .It amr%d: I/O beyond end of unit (%u,%d > %u)
207 A partitioning error or disk corruption has caused an I/O request
208 beyond the end of the logical drive.
209 This may also occur if FlexRAID Virtual Sizing is enabled and
210 an I/O operation is attempted on a portion of the virtual drive
211 beyond the actual capacity available.
212 .It amr%d: polled command timeout
214 An initialisation command timed out.
215 The initialisation process may fail as a result.
216 .It amr%d: bad slot %d completed
218 The controller reported completion of a command that the driver did not issue.
219 This may result in data corruption,
220 and suggests a hardware or firmware problem with the system or controller.
221 .It amr%d: I/O error - %x
223 An I/O error has occurred.
