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.Bl -tag -width rebuild
75.It status
76Print the status of controllers and system drives.
77If one or more drives are specified,
78only print information about these drives,
79otherwise print information
80about all controllers and drives in the system.
81With the
82.Fl v
83flag, display much more verbose information.
84With the
85.Fl q
86flag, do not print any output.
87This command returns
880 if all drives tested are online,
891 if one or more drives are critical and
902 if one or more are offline.
91.It rescan
92Rescan one or more controllers for non-attached system drives
93(e.g.\& drives that have been
94detached or created subsequent to driver initialisation).
95If the
96.Fl a
97flag is supplied, rescan all controllers in the system.
98.It detach
99Detach one or more system drives.
100Drives must be unmounted
101and not opened by any other utility for this command to succeed.
102If the
103.Fl a
104flag is supplied, detach all system drives from the nominated controller.
105.It check
106Initiate a consistency check and repair pass on a redundant system drive
107(e.g.\& RAID1 or RAID5).
108The controller will scan the system drive and repair any inconsistencies.
109This command returns immediately;
110use the
111.Ar status
112command to monitor the progress of the check.
113.It rebuild
114Requires two arguments,
115.Ar controller
116and
117.Ar physdrive
118as specified in the
119output of the
120.Ar status
121command.
122All system drives using space on the physical drive
123.Ar physdrive
124are rebuilt, reconstructing all data on the drive.
125Note that each controller can only perform one rebuild at a time.
126This command returns immediately; use the
127.Ar status
128command to monitor the progress of the rebuild.
129.It config
130Print the current configuration from the nominated controller.
131This command will be updated
132to allow addition/deletion of system drives from a configuration
133in a future release.
134.It help
135Print usage information for
136.Ar command .
