60.Sh DESCRIPTION
61The
62.Nm
63utility provides status monitoring and management functions
64for devices attached
65to the
66.Xr mlx 4
67driver.
68.Pp
69Controller names are of the form "mlxN"
70where N is the unit number of the controller.
71Drive names are of the form "mlxdN"
72where N is the unit number of the drive.
73Do not specify the path to a device node.
74.Pp
75.Bl -tag -width rebuild
76.It status
77Print the status of controllers and system drives.
78If one or more drives are specified,
79only print information about these drives,
80otherwise print information
81about all controllers and drives in the system.
82With the
83.Fl v
84flag, display much more verbose information.
85With the
86.Fl q
87flag, do not print any output.
88This command returns
890 if all drives tested are online,
901 if one or more drives are critical and
912 if one or more are offline.
92.It rescan
93Rescan one or more controllers for non-attached system drives
94(e.g.\& drives that have been
95detached or created subsequent to driver initialisation).
96If the
97.Fl a
98flag is supplied, rescan all controllers in the system.
99.It detach
100Detach one or more system drives.
101Drives must be unmounted
102and not opened by any other utility for this command to succeed.
103If the
104.Fl a
105flag is supplied, detach all system drives from the nominated controller.
106.It check
107Initiate a consistency check and repair pass on a redundant system drive
108(e.g.\& RAID1 or RAID5).
109The controller will scan the system drive and repair any inconsistencies.
110This command returns immediately;
111use the
112.Ar status
113command to monitor the progress of the check.
114.It rebuild
115Requires two arguments,
116.Ar controller
117and
118.Ar physdrive
119as specified in the
120output of the
121.Ar status
122command.
123All system drives using space on the physical drive
124.Ar physdrive
125are rebuilt, reconstructing all data on the drive.
126Note that each controller can only perform one rebuild at a time.
127This command returns immediately; use the
128.Ar status
129command to monitor the progress of the rebuild.
130.It config
131Print the current configuration from the nominated controller.
132This command will be updated
133to allow addition/deletion of system drives from a configuration
134in a future release.
135.It help
136Print usage information for
137.Ar command .
138.El
139.Sh BUGS
140The
141.Ar config
142command does not yet support modifying system drive configuration.
143.Pp
144Error log extraction is not yet supported.
