260.Sh DESCRIPTION
261The
262.Nm
263utility can be used to display or modify various parameters on LSI
264MegaRAID SAS RAID controllers.
265Each invocation of
266.Nm
267consists of zero or more global options followed by a command.
268Commands may support additional optional or required arguments after the
269command.
270.Pp
271Currently three global options are supported:
272.Bl -tag -width indent
273.It Fl D Ar device
274.Ar device
275specifies the device node of the controller to use.
276'/dev/' will be added to the device node if needed.
277If no device node is specified,
278then device will be made of the type and device.
279.It Fl t Ar type
280.Ar type
281specifies the type of the controller to work with either
282.Xr mfi 4
283or
284.Xr mrsas 4 .
285If no type is specified,
286then the name of the invoked tool used to derive the type.
287.It Fl u Ar unit
288.Ar unit
289specifies the unit of the controller to work with.
290If no unit is specified,
291then unit 0 is used.
292.El
293.Pp
294Various commands accept either or both of the two options:
295.Bl -tag -width indent
296.It Fl d
297Print numeric device IDs as drive identifier.
298This is the default.
299Useful in combination with
300.Fl e
301to print both, numeric device IDs and enclosure:slot information.
302.It Fl e
303Print drive identifiers in enclosure:slot form.
304See next paragraph on format details in context of input rather than
305output.
306.El
307.Pp
308Drives may be specified in two forms.
309First,
310a drive may be identified by its device ID.
311The device ID for configured drives can be found in
312.Cm show config .
313Second,
314a drive may be identified by its location as
315.Sm off
316.Op E Ar xx Ns \&:
317.Li S Ns Ar yy
318.Sm on
319where
320.Ar xx
321is the enclosure
322and
323.Ar yy
324is the slot for each drive as displayed in
325.Cm show drives .
326.Pp
327Volumes may be specified in two forms.
328First,
329a volume may be identified by its target ID.
330Second,
331on the volume may be specified by the corresponding
332.Em mfidX
333device,
334such as
335.Em mfid0 .
336.Pp
337The
338.Nm
339utility supports several different groups of commands.
340The first group of commands provide information about the controller,
341the volumes it manages, and the drives it controls.
342The second group of commands are used to manage the physical drives
343attached to the controller.
344The third group of commands are used to manage the logical volumes
345managed by the controller.
346The fourth group of commands are used to manage the drive configuration for
347the controller.
348The fifth group of commands are used to manage controller-wide operations.
349.Pp
350The informational commands include:
351.Bl -tag -width indent
352.It Cm version
353Displays the version of
354.Nm .
355.It Cm show adapter

374The controller maintains a circular buffer of events.
375Each event is tagged with a class and locale.
376.Pp
377The
378.Ar class
379parameter limits the output to entries at the specified class or higher.
380The default class is
381.Dq warn .

412.Dq sas ,
413.Dq controller ,
414.Dq config ,
415.Dq cluster ,
416and
417.Dq all .
418.Pp
419The
420.Ar count
421parameter is a debugging aid that specifies the number of events to fetch from
422the controller for each low-level request.
423The default is 15 events.
424.Pp
425By default, matching event log entries from the previous shutdown up to the
426present are displayed.
427This range can be adjusted via the
428.Ar start
429and
430.Ar stop
431parameters.
