RAID level of array = false?
I created a RAID 5 array and when I list out the attributes of the "hdisk" it reports back raid_level = 5 but the RAID level of the array = false. What does this actually indicate about my array? I've never paid much attention to this until now since I have a disk reporting failure I want to make sure I am (was?) working with a raid 5 array so I can rebuild the disk.


<host>:/# lsattr -El hdisk5
pvid none Physical volume identifier False
queue_depth 16 Queue DEPTH True
raid_level 5 RAID level of the array False
read_ahead no Read ahead enabled False
size 277720 Capacity of the array in MB False

ataraid

ATARAID(4)						   BSD Kernel Interfaces Manual 						ATARAID(4)

NAME

     ataraid -- software BIOS RAID

SYNOPSIS

     pseudo-device ataraid
     ld* at ataraid? vendtype ? unit ?

DESCRIPTION

     The ataraid driver provides support for BIOS-based software RAID controllers.  These are devices which have some simple support for several
     basic RAID levels (often RAID 0 and RAID 1), but which require software support to actually perform the RAID function.  The BIOS support is
     largely just to create and recognize the array so that it may be a boot device.

     The driver currently supports RAID formats from:
	   o   Adaptec HostRAID (found in Intel 6300ESB)
	   o   Intel MatrixRAID
	   o   JMicron RAID
	   o   nVidia MediaShield
	   o   Promise FastTrak
	   o   Via V-RAID (found in many VIA-based motherboards)

     Status of the logical disk as well as the disks associated with it, can be viewed through the bioctl(8) utility.

SEE ALSO

     ld(4), bioctl(8)

HISTORY

     The ataraid driver first appeared in NetBSD 2.0.

AUTHORS

     The ataraid driver was originally adapted from FreeBSD by Jason Thorpe <thorpej@NetBSD.org>.

BUGS

     Not all features of the software RAID are currently recognized or supported.  For example, the Adaptec support doesn't recognize when a RAID
     1 should be in a ``building'' state, and it does not do the right thing.

     At least part of the reason for this is that the publically-available information on these formats is quite limited.
