-.SH DESCRIPTION
-dmraid discovers block and software RAID devices (eg, ATARAID)
-by using multiple different metadata format handlers which
-support various formats (eg, Highpoint 37x series).
-It offers activating RAID sets made up by 2 or more
-discovered RAID devices, display properties of devices and sets (see option
-.B -l
-for supported metadata formats).
-Block device access to activated RAID sets occurs via device-mapper nodes
-/dev/mapper/RaidSetName.
-RaidSetName starts with the format name (see
-.B -l
-option) which can be used to access all RAID sets of a specific format
-easily with certain options (eg,
-.B -a
-below).
-
-.SS OPTIONS
-.TP
-.I \-a, \-\-activate {y|n} [RAID set...]
-Activates or deactivates all or particular software RAID set.
-In case metadata format handlers are chosen with
-.B -f
-, only RAID sets with such format(s) can be activated or deactivated.
-Useful if devices have multiple metadata signatures.
-When activating RAID sets,
-.B -p
-disables the activation of partitions on them, and
-.B -Z
-will make dmraid tell the kernel to remove the partitions from the disks
-underlying the set, ie if sda is part of the set, remove sda1, sda2, etc.
-This prevents applications from directly accessiong the disks bypassing dmraid.
-RAID set names given on command line don't need to be fully specified
-(eg, "dmraid -ay sil" would activate all discovered Silicon Image Medley
-RAID sets).
-
-.TP
-.I {-b|--block_devices} [device-path...]
-List all or particular discovered block devices with their
-properties (size, serial number).
-Add
-.B -c
-to display block device names only and
-.B -cc
-for CSV column output of block device properties.
-See description of
-.B -c
-below for FIELD identifiers.
-
-.TP
-.I [-d|--debug]...
-Enable debugging output. Opion can be given multiple times
-increasing the debug output level.
