28.Os
29.Sh NAME
30.Nm amr
31.Nd MegaRAID SCSI/ATA/SATA RAID driver
32.Sh SYNOPSIS
33To compile this driver into the kernel,
34place the following lines in your
35kernel configuration file:
36.Bd -ragged -offset indent
37.Cd "device pci"
38.Cd "device scbus"
39.Cd "device amr"
40.Ed
41.Pp
42To compile in debugging code:
43.Bd -ragged -offset indent
44.Cd options AMR_DEBUG=x # x=3 is maximum verbosity
45.Ed
46.Pp
47Alternatively, to load the driver as a
48module at boot time, place the following line in
49.Xr loader.conf 5 :
50.Bd -literal -offset indent
51amr_load="YES"
52.Ed
53.Sh DESCRIPTION
54The
55.Nm
56driver provides support for LSI Logic MegaRAID SCSI, ATA and SATA
57RAID controllers and legacy American Megatrends MegaRAID
58SCSI RAID controllers, including models relabeled
59and sold by Dell and Hewlett-Packard.
60.Pp
61LSI MegaRAID SAS controllers are supported by
62.Xr mfi 4
63and will not work with this driver.

164Compiling with
165.Dv AAC_DEBUG
166will enable debug messages.
167.Ss Driver initialisation/shutdown phase
168.Bl -diag
169.It amr%d: memory window not available
170.It amr%d: I/O window not available
171.Pp
172The PCI BIOS did not allocate resources necessary for the correct operation of
173the controller.
174The driver cannot attach to this controller.
175.It amr%d: busmaster bit not set, enabling
176.Pp
177The PCI BIOS did not enable busmaster DMA,
178which is required for the correct operation of the controller.
179The driver has enabled this bit and initialisation will proceed.
180.It amr%d: can't allocate register window
181.It amr%d: can't allocate interrupt
182.It amr%d: can't set up interrupt
183.It amr%d: can't allocate parent DMA tag
184.It amr%d: can't allocate buffer DMA tag
185.It amr%d: can't allocate scatter/gather DMA tag
186.It amr%d: can't allocate s/g table
187.It amr%d: can't allocate mailbox tag
188.It amr%d: can't allocate mailbox memory
189.Pp
190A resource allocation error occurred while initialising the driver;
191initialisation 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
194.Pp
195The driver was unable to obtain vital configuration data from the controller.
196Initialisation 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
199.Pp
200The scan for logical drives managed by the controller failed.
201No drives will be attached.
202.It amr%d: device_add_child failed
203.It amr%d: bus_generic_attach returned %d
204.Pp
205Creation of the logical drive instances failed;
206attachment of one or more logical drives may have been aborted.
207.It amr%d: flushing cache...
208.Pp
209The controller cache is being flushed prior to shutdown or detach.
210.El
211.Ss Operational diagnostics
212.Bl -diag
213.It amr%d: I/O beyond end of unit (%u,%d > %u)
214.Pp
215A partitioning error or disk corruption has caused an I/O request
216beyond the end of the logical drive.
217This may also occur if FlexRAID Virtual Sizing is enabled and
218an I/O operation is attempted on a portion of the virtual drive
219beyond the actual capacity available.
220.It amr%d: polled command timeout
221.Pp
222An initialisation command timed out.
223The initialisation process may fail as a result.
224.It amr%d: bad slot %d completed
225.Pp
226The controller reported completion of a command that the driver did not issue.
227This may result in data corruption,
228and suggests a hardware or firmware problem with the system or controller.
229.It amr%d: I/O error - %x
230.Pp
231An I/O error has occurred.
