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 To compile in debugging code:
43 .Bd -ragged -offset indent
44 .Cd options AMR_DEBUG=x # x=3 is maximum verbosity
47 Alternatively, to load the driver as a
48 module at boot time, place the following line in
50 .Bd -literal -offset indent
56 driver provides support for LSI Logic MegaRAID SCSI, ATA and SATA
57 RAID controllers and legacy American Megatrends MegaRAID
58 SCSI RAID controllers, including models relabeled
59 and sold by Dell and Hewlett-Packard.
61 LSI MegaRAID SAS controllers are supported by
63 and will not work with this driver.
65 Controllers supported by the

174 The driver cannot attach to this controller.
175 .It amr%d: busmaster bit not set, enabling
177 The PCI BIOS did not enable busmaster DMA,
178 which is required for the correct operation of the controller.
179 The driver has enabled this bit and initialisation will proceed.

190 A resource allocation error occurred while initialising the driver;
191 initialisation has failed and the driver will not attach to this controller.
192 .It amr%d: can't obtain configuration data from controller
193 .It amr%d: can't obtain product data from controller
195 The driver was unable to obtain vital configuration data from the controller.
196 Initialisation has failed and the driver will not attach to this controller.
197 .It amr%d: can't establish configuration hook
198 .It amr%d: can't scan controller for drives
200 The scan for logical drives managed by the controller failed.
201 No drives will be attached.
202 .It amr%d: device_add_child failed
203 .It amr%d: bus_generic_attach returned %d
205 Creation of the logical drive instances failed;
206 attachment of one or more logical drives may have been aborted.
207 .It amr%d: flushing cache...
209 The controller cache is being flushed prior to shutdown or detach.
211 .Ss Operational diagnostics
213 .It amr%d: I/O beyond end of unit (%u,%d > %u)
215 A partitioning error or disk corruption has caused an I/O request
216 beyond the end of the logical drive.
217 This may also occur if FlexRAID Virtual Sizing is enabled and
218 an I/O operation is attempted on a portion of the virtual drive
219 beyond the actual capacity available.
220 .It amr%d: polled command timeout
222 An initialisation command timed out.
223 The initialisation process may fail as a result.
224 .It amr%d: bad slot %d completed
226 The controller reported completion of a command that the driver did not issue.
227 This may result in data corruption,
228 and suggests a hardware or firmware problem with the system or controller.
229 .It amr%d: I/O error - %x
231 An I/O error has occurred.
