1first put to the first hard disk to dump and then the target disk
2boot on the hard disk to you want to dump
3 format and partition the the target hardisk partition size same as harddisc to dump
4enter this command

ufsdump 0f - / | ( cd /cop/0 ; ufsrestore -rf - )
ufsdump 0f - /export/home | ( cd /cop/7 ; ufsrestore -rf - )

this two command will dump the root and home partition

installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t3d0s0

this command install the bootblk to your target disk

c0t3d0s0 is the target disk
