In short: Watching the configuration...Can I said if the filesystem / is in Raid?

Thanks in Advanced,
AGAD

hptmv

HPTMV(4)						   BSD Kernel Interfaces Manual 						  HPTMV(4)

NAME

     hptmv -- HighPoint RocketRAID 182x device driver

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device hptmv

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   hptmv_load="YES"

DESCRIPTION

     The hptmv driver provides support for HighPoint's RocketRAID 182x based RAID controller.

     These devices support ATA disk drives and provide RAID0 (striping), RAID1 (mirroring), and RAID5 functionality.

HARDWARE

     The hptmv driver supports the following ATA RAID controllers:

     o	 HighPoint's RocketRAID 182x series

NOTES

     The hptmv driver only works on the i386 and amd64 platforms as it requires a binary blob object from the manufacturer which they only supply
     for these platforms.  The hptmv driver does not work on i386 with pae(4) enabled.

SEE ALSO

     kld(4), kldload(8), loader(8)

HISTORY

     The hptmv device driver first appeared in FreeBSD 5.3.

AUTHORS

     The hptmv device driver was written by HighPoint Technologies, Inc., and ported to FreeBSD by Scott Long.	This manual page was written by
     David E. O'Brien.

BUGS

     The hptmv driver does not support manipulating the RAID from the OS, RAIDs need to be set up from the on-board BIOS.
