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!

installboot

installboot(1M) 														   installboot(1M)

NAME

       installboot - install bootblocks in a disk partition

SYNOPSIS

       installboot bootblk raw-disk-device

       The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.

       The  ufs  boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
       found using the -i option of uname(1).

       The installboot utility is a SPARC only program. It is not supported on the  architecture.  users should use installgrub(1M) instead.

       bootblk	       The name of the bootblock code.

       raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is  read-
		       able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.

       Example 1: Installing UFS Boot Block

       To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:

	      example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
		   /dev/rdsk/c1t0d0s0

       /usr/platform/platform-name/lib/fs/ufs

	   directory where ufs boot objects reside.

       /platform/platform-name/ufsboot

	   second level program to boot from a disk or CD

WARNINGS

       The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
