SYNOPSIS


.Cd "device twa"

DESCRIPTION

The twa driver provides support for the AMCC’s 3ware 9000 series SATA controllers.

These controllers are available in 4, 8 or 12-port configurations, and support the following RAID levels: 0, 1, 10, 5, 50. The device nodes for the controllers are of the form /dev/twa X, where X is the controller number. The driver is implemented as a SCSI SIM under CAM, and, as such, the logical units that it controls are accessible via the device nodes, /dev/da Y, where Y is the logical unit number.

HARDWARE

The twa driver supports the following SATA RAID controllers:

  • AMCC’s 3ware 9500S-4LP
  • AMCC’s 3ware 9500S-8
  • AMCC’s 3ware 9500S-8MI
  • AMCC’s 3ware 9500S-12
  • AMCC’s 3ware 9500S-12MI

DIAGNOSTICS

Whenever the driver encounters a command failure, it prints out an error code in the format: ""ERROR: (<error source>: <error code>):"", followed by a text description of the error. There are other error messages and warnings that the driver prints out, depending on the kinds of errors that it encounters. If the driver is compiled with TWA_DEBUG defined, it prints out a whole bunch of debug messages, the quantity of which varies depending on the value assigned to TWA_DEBUG (0 to 10).
