由于AIX系统空间不够需要增加硬盘，希望增加文件系统的空间，折腾了好几天怎么都不能扩展文件系统的空间，原来是把硬盘加错了卷组
首先，确定文件系统所在的LV
/dev/datalv
270.00 37.47
87% 24 1%
/oradata
2.查看LV所在的卷组
#
lslv datalv
LOGICAL VOLUME:
datalv VOLUME GROUP: backupvg
LV IDENTIFIER:

3.把硬盘加入到相应的卷组中
#
smit vg
选择Set
Characteristics of a Volume GroupSet Characteristics of a Volume Group
选择Add
a Physical Volume to a Volume Group---把硬盘增加到相应的卷组中
4.查看
#

5.增加文件系统的空间
#
chfs -a size=+100G /oradata
Filesystem size changed to 775946240
6，确认
/dev/datalv 370.00
137.45 63%
24 1% /oradata
成功！
