ufsrestore will not boot

hey all,

i did a ufsdump/restore from a mirrored system and i'm not able to get the new system to boot off of the dump.

system 1 is a v245 mirrored with disk suite. metadb's are in place

d3 -m d23 d13 d33 1
d23 1 1 c1t1d0s3
d13 1 1 c1t0d0s3
d33 1 1 c1t2d0s3
d0 -m d20 d10 d30 1
d20 1 1 c1t1d0s0
d10 1 1 c1t0d0s0
d30 1 1 c1t2d0s0
d1 -m d11 d31 1
d11 1 1 c1t0d0s1
d31 1 1 c1t2d0s1

i placed my a clean drive into slot 3 and did the following.

$ prtvtoc /dev/rdsk/c1t0d0s0 | fmthard -s - /dev/rdsk/c1t3d0s0

$ newfs /dev/dsk/c1t3d0s0

$ mount /dev/dsk/c1t3d0s0 /mnt2

$ ufsdump 0f - / | (cd /mnt2; ufsrestore rf -)

DUMP: DUMP IS DONE

$ installboot /usr/platform/sun4u/lib/fs/ufs/bootblk /dev/rdsk/c1t3d0s0

$ umount /mnt2

removed the drive from slot 3 and placed it into system 2 (v245 as well) and at the ok prompt typed boot or boot disk, but the system won't boot.

I think you will find you will need to undo what SDS did to the /etc/system and /etc/vfstab files while the root disk is still mounted as /mnt2.

Boot system to cdrom. Mount disk device.
Change the vfstab entries to point raw device "/dev/dsk /dev/rdsk". Remove the md, rootdev entries in the system file.

I tried both and I still get the same error.

is there a way to update the PROM if the system doesn't boot? This system is on an older boot PROM, 4.25 I believe and there appears to be a patch to fix this issue with the 4.30 PROM, but how do I install it if I can't the system to boot?
