For the complete backup you need the following slices:
/root on slice 0
/usr on slice 6
/export on slice 5
/w.local on slice 7
If you have mount the second disk at /mnt you can use this:
ufsdump -f /mnt/dump_root /root
ufsdump -f /mnt/dump_usr /usr
ufsdump -f /mnt/dump_export /export
ufsdump -f /mnt/dump_w.local /w.local
Now on the second disk are four new files :
cd /mnt
ls
dump_root
dump_usr
dump_export
dump_w.local
The reason that the mirrored disk can not boot is the not available boot sector at the second disk.
This command to create a boot block.
installboot /usr/platform/sun4m/lib/fs/ufs/bootblk /dev/rdsk/c0t1d0s0
Best regards

NAME
installgrub - install GRUB in a disk partition or a floppy
SYNOPSIS
/sbin/installgrub [-fm] stage1 stage2 raw-device
The installgrub command is an -only program. GRUB stands for GRand Unified Bootloader.
installgrub installs GRUB stage 1 and stage 2 files on the boot area of a disk partition. If you specify the -m option, installgrub
installs the stage 1 file on the master boot sector of the disk.
The installgrub command accepts the following options:
-f
Suppresses interaction when overwriting the master boot sector.
-m
Installs GRUB stage1 on the master boot sector interactively.
The installgrub command accepts the following operands:
stage1
The name of the GRUB stage 1 file.
stage2
The name of the GRUB stage 2 file.
raw-device
The name of the device onto which GRUB code is to be installed. It must be a character device that is readable and writable. For disk
devices, specify the slice where the GRUB menu file is located. (For Solaris it is the root slice.) For a floppy disk, it is
/dev/rdiskette.
Example 1: Installing GRUB on a Hard Disk Slice
The following command installs GRUB on a system where the root slice is c0d0s0:
example# /sbin/installgrub /boot/grub/stage1
/boot/grub/stage2 /dev/rdsk/c0d0s0
Example 2: Installing GRUB on a Floppy
The following command installs GRUB on a formatted floppy:
example# mount -F pcfs /dev/diskette /mnt
# mkdir -p /mnt/boot/grub
# cp /boot/grub/* /mnt/boot/grub
# umount /mnt
# cd /boot/grub
# /sbin/installgrub stage1 stage2 /dev/rdiskette
/boot/grub
Directory where GRUB files reside.

Installing GRUB on the master boot sector (-m option) overrides any boot manager currently installed on the machine. The system will always
boot the GRUB in the Solaris partition regardless of which fdisk partition is active.
