< 주의 >기존의 OS파티션과 새로운 디스크의 파티션을 같게 한다.
c0t3d0 ( Solaris 2.6이 인스톨 되어 있음 ) 을 c0t1d0 ( t3 disk의 Solaris 2.6 slices/partitions을 copy할 디스크 )
다음과 같은 작업을 할 것이다.
c0t3d0s0 / -> c0t1d0s0 / 복사하고
c0t3d0s4 /var -> c0t1d0s4 /var 복사하고
c0t3d0s5 /opt -> c0t1d0s5 /opt 복사하고
c0t3d0s6 /usr -> c0t1d0s6 /usr 복사 할 것입니다
[6] 새로운 디스크를 마운트 하기위해 newfs (new file system)를 실행 합니다.
각각의 파티션을 다음과 같이 실행 합니다.
# newfs -v /dev/rdsk/c0t1d0s0
# newfs -v /dev/rdsk/c0t1d0s4
# newfs -v /dev/rdsk/c0t1d0s5
# newfs -v /dev/rdsk/c0t1d0s6
[7] fsck 를 실행 시켜서 마운트를 순조롭게 합니다.
# fsck /dev/rdsk/c0t1d0s0
# fsck /dev/rdsk/c0t1d0s4
# fsck /dev/rdsk/c0t1d0s5
# fsck /dev/rdsk/c0t1d0s6
[8] 마운트 포인트 디렉터리를 만듭니다.
기존 디스크의 파티션 수만큼 디렉터리를 만듭니다.
# mkdir /root2
# mkdir /var2
# mkdir /opt2
# mkdir /usr2
[9] 새로운 파티션을 위에서 만들어 놓은 디렉터리로 마운트 합니다.
# mount /dev/dsk/c0t1d0s0 /root2
# mount /dev/dsk/c0t1d0s4 /var2
# mount /dev/dsk/c0t1d0s5 /opt2
# mount /dev/dsk/c0t1d0s6 /usr2
[10] 이제부터 옮깁니다 ~~
# cd /
# ufsdump 0f - /dev/rdsk/c0t3d0s0 | (cd /root2; ufsrestore xf -)
# ufsdump 0f - /dev/rdsk/c0t3d0s4 | (cd /var2; ufsrestore xf -)
# ufsdump 0f - /dev/rdsk/c0t3d0s5 | (cd /opt2; ufsrestore xf -)
# ufsdump 0f - /dev/rdsk/c0t3d0s6 | (cd /usr2; ufsrestore xf -)
# cd /usr
# ufsdump 0f - /usr | (cd /usr2; ufsrestore xf - )

[11] fsck를 실행 해서 복사한 디스크를 정리 합니다.
# fsck /dev/rdsk/c0t1d0s0
# fsck /dev/rdsk/c0t1d0s4
# fsck /dev/rdsk/c0t1d0s5
# fsck /dev/rdsk/c0t1d0s6
[12.] 새로운 디스크의 /mount_point/etc/vfstab 파일을 수정 합니다.
# cd /root2 (기존의 t3부분을 t1으로 바꿉니다.)
# vi /root2/etc/vfstab
주의 하세요 !!
#device device mount FS fsck mount mount

:wq!
[13] 이제는 새로운 디스크에 installboot 을 사용하여 bootblk 을 설정하는 작업
입니다.
시스템을 halt 하시고 다음과 같이 합니다.
ok boot cdrom -sw
Solaris 2.5 나 그 이상의 버전은 이렇게 하시면 됩니다.
/usr/platform/`uname -i`/lib/fs/ufs/bootblk
<주의> 위에서 ‘uname –a`는 시스템 구동시에 확인한 시스템 사양을 의미 합니다.
Solaris 2.4 나 그 이하 버전은 이렇게 하세요
/usr/lib/fs/ufs/bootblk
Solaris 2.5 이상이라 가정 하고 다음과 같이 합니다.
# /usr/sbin/installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk \
/dev/rdsk/c0t1d0s0
