If your HDD with system is dying, you have the same HDD (in matter of size), and you`re using UFS - you could do the next steps to completly recreate this disk to a new one:

1. Check the disks (with attached new one):

# format

2. Copy the VTOC from old one to a new one:

# prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c1t0d0s2

3. Create new filesystem:

# newfs /dev/rdsk/c1t0d0s0

4. Mount slice to copy to:

#mount /dev/rdsk/c1t0d0s0 /mnt

5. UFSdump from old slice to a new mounted one:

# ufsdump 0f - /dev/rdsk/c0t0d0s0 | (cd /mnt && ufsrestore rf - )

6. Umount the new slice, with dumped information from from old one:

# umount /mnt

Steps 3 - 6 should be repeated for each slice to migrate.

7. Install bootblocks into a new disk partition:

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

That`s it, grab a beer
