可以看出，这个vg里每个pp大小为128m，剩余87个pp，即剩余11G
#smitty hacmp ->System Management (C-SPOC)->HACMP Logical Volume Management-> Shared Logical Volumes->Add a
Shared Logical Volume，选择在哪个vg上创建，自动选择磁盘，创建lv,注意：
Number of LOGICAL PARTITIONS里输入创建的pp数，例如创建5G的lv，则输入40（40*128=5120m）
lv名称里输入将创建的lv名称，如maindb_index2_5g
创建完成后，需要按esc+3回退到上层目录， Change a Shared Logical Volume，将这个lv的类型由jfs修改为raw
回车执行完成后按esc+0退出。
#cd /dev
#ls maindb_index2_5g
ls rmaindb_index2_5g
即可查看到刚刚创建的lv名称.
# chown -R oracle:dba /dev/rmaindb_index2_10g 修改文件宿主
# chmod -R 644 /dev/rmaindb_index2_10g 修改文件权限
