31 .Nd Mylex DAC-family RAID management utility
63 utility provides status monitoring and management functions
69 Controller names are of the form "mlxN"
70 where N is the unit number of the controller.
71 Drive names are of the form "mlxdN"
72 where N is the unit number of the drive.
73 Do not specify the path to a device node.
74 .Bl -tag -width rebuild
76 Print the status of controllers and system drives.
77 If one or more drives are specified,
78 only print information about these drives,
79 otherwise print information
80 about all controllers and drives in the system.
83 flag, display much more verbose information.
86 flag, do not print any output.
88 0 if all drives tested are online,
89 1 if one or more drives are critical and
90 2 if one or more are offline.
92 Rescan one or more controllers for non-attached system drives
93 (e.g.\& drives that have been
94 detached or created subsequent to driver initialisation).

109 This command returns immediately;
112 command to monitor the progress of the check.
114 Requires two arguments,
