34 .Nd 3ware 9000 series SATA RAID controllers driver
40 driver provides support for the AMCC's 3ware 9000 series SATA controllers.
42 These controllers are available in 4, 8 or 12-port configurations,
43 and support the following RAID levels: 0, 1, 10, 5, 50.
44 The device nodes for the controllers are of the form
45 .Pa /dev/twa Ns Ar X ,
48 is the controller number.
49 The driver is implemented as a SCSI SIM
50 under CAM, and, as such, the logical units that it controls are accessible
55 is the logical unit number.
59 driver supports the following SATA RAID controllers:
63 AMCC's 3ware 9500S-4LP
67 AMCC's 3ware 9500S-8MI
71 AMCC's 3ware 9500S-12MI
74 Whenever the driver encounters a command failure, it prints out an error code in
76 .Qq Li "ERROR: (<error source>: <error code>):" ,
77 followed by a text description of the error.
78 There are other error messages and warnings that the
79 driver prints out, depending on the kinds of errors that it encounters.
80 If the driver is compiled with
82 defined, it prints out a whole bunch of debug
83 messages, the quantity of which varies depending on the value assigned to
89 driver and manpage were written by
