70 where N is the unit number of the drive.
71 Do not specify the path to a device node.
72 .Bl -tag -width rebuild
74 Print the status of controllers and system drives.
75 If one or more drives are specified,
76 only print information about these drives,
77 otherwise print information
78 about all controllers and drives in the system.
81 flag, display much more verbose information.
84 flag, do not print any output.
86 0 if all drives tested are online,
87 1 if one or more drives are critical and
88 2 if one or more are offline.
90 Rescan one or more controllers for non-attached system drives
91 (e.g.\& drives that have been
92 detached or created subsequent to driver initialisation).
95 flag is supplied, rescan all controllers in the system.
97 Detach one or more system drives.
98 Drives must be unmounted

107 This command returns immediately;
110 command to monitor the progress of the check.
112 Requires two arguments,
120 All system drives using space on the physical drive
122 are rebuilt, reconstructing all data on the drive.
123 Note that each controller can only perform one rebuild at a time.
