# mount /dev/md/dsk/d1 /d1
# df -k

1. SVM 디스크 환경 설정
    - SVM의 구성정보와 상태정보를 저장하는 database영역 : c0t0d0s0    50mb
    - volume 구성을 위한 영역 : c0t0d0s3, c0t0d0s4, c0t0d0s5    500mb

2. metadb 영역 생성

     a        u         16400          8192            /dev/dsk/c0t0d0s0

 r - replica does not have device relocation information
 o - replica active prior to last mddb configuration change
 u - replica is up to date
 l - locator for this replica was read successfully
 c - replica's location was in /etc/lvm/mddb.cf
 p - replica's location was patched in kernel
 m - replica is master, this is replica selected as input
 W - replica has device write errors
 a - replica is active, commits are occurring to this replica
 M - replica had problem with master blocks
 D - replica had problem with data blocks
 F - replica had format problems
 S - replica is too small to hold current data base
 R - replica had device read errors
