Setting up bootblock on RAID 0 SVM

Hi All!

I'm running Solaris 10 and SPARC and using

Let me give a bit of background before asking my question:

I have created a RAID 0 (stripe) on 2 disks, I have the OS running on a third disk and I have now performed a ufsdump / ufsrestore from my third disk to the RAID 0 disks (/dev/md/dsk/d10)

From what I understand, ufsrestore does NOT carry over bootblock data and this is fine and dandy on a single drive, but when I try to add the bootblock to the RAID 0 I get the following:

# /usr/sbin/installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/md/dsk/d10
/dev/md/dsk/d10: Not a character device

I know I still need to run metaroot but that is for mounting the disk AFTER I boot the system (is this the correct logic?)

If anyone could point me in the right direction it would be greatly appreciated; I searched the forums and google but I can't seem to find anything for a RAID 0

I noticed with a RAID 1, you are to setup the bootblock BEFORE you setup RAID 1, but how do you setup RAID 0 with a bootblock?

Thanks so much everyone!

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.
