第一步：创建PV，把cOt2d0这块磁盘加入到一个PV #pvcreate /dev/rdsk/cOt2d0
//此时磁盘为裸设备，所以是rdsk Physical volume"/dev/rdsk/cOt2d0”has been successfully created.
第二步:创建VG
#mkdir /dev/vg01
#mknod /dev/vg01/group c 64 Ox010000//创建一个控制器文件，指定主号为64，次号为Ox010000#vgcreate /dev/vg01/dev/dsk/cOt2d0//从cOt2d0这个磁盘去创建一个vg01Increased the number of physical extents per physical volume to 8683.
Volume
group"/dev/vg01"has been successfully created.
Volume Group configuration for devlvg01 has been saved in etc/lvmconf/vg01.conf
第三步:创建LV#lvcreate-L200·n lv_test vg01//从vg01中创建一个名为lv_backup大小为200M的文件系统Logical volume"ldev/vg01/lv test"has been successfully created with character device"/dev/vg01/rlv_backup".
Logical volume"ldev/vg01/lv_backup”has been successfully extended.
Volume
Group
configuration for dev/vg01 has been saved in etc/lvmconf/vg01.conf 第四步:创建文件系统
#newfs Fvxfsldev/vg01/rlv_backup //创建文件系统，可以不加-Fvxfs参数，默认就是vxfs文件系统
