/etc/vfstab原先bash-3.00# vi /etc/vfstab
#device       device       mount          FS    fsck mount mount
#to mount    to fsck       point          type pass at boot options
#
fd    -    /dev/fd fd    -    no    -
/proc -    /proc proc -    no    -
/dev/dsk/c0t0d0s1    -    -    swap -    no    -
/dev/md/dsk/d0  /dev/md/rdsk/d0 /    ufs    1    no    -
/dev/dsk/c0t0d0s5    /dev/rdsk/c0t0d0s5    /usr ufs    1    no
-
/dev/dsk/c0t0d0s4    /dev/rdsk/c0t0d0s4    /var ufs    1    no
-
/dev/dsk/c0t0d0s6    /dev/rdsk/c0t0d0s6    /data ufs    2    yes
-
/dev/dsk/c0t0d0s3    /dev/rdsk/c0t0d0s3    /opt ufs    2    yes
-
/devices       -    /devices       devfs -    no    -
sharefs -    /etc/dfs/sharetab    sharefs -    no    -
ctfs -    /system/contract       ctfs -    no    -
objfs -    /system/object  objfs -    no    -
swap -    /tmp tmpfs -    yes    -
~

然后做了镜像修改了/etc/vfstab
/dev/md/dsk/c0t0d0s1 -    -    swap -    no    -
/dev/md/dsk/d0  /dev/md/rdsk/d0 /    ufs    1    no    -
/dev/md/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5    /usr ufs    1    no
-
/dev/md/dsk/c0t0d0s4 /dev/rdsk/c0t0d0s4    /var ufs    1    no
-
/dev/md/dsk/c0t0d0s6 /dev/rdsk/c0t0d0s6    /data ufs    2    yes
-
/dev/md/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5    /usr ufs    1    no
-

重启后出现了如下的提示
