一、添加lun到VG 

1、# cfgmgr    扫描新磁盘
Method error (/usr/lib/methods/cfgefscsi -l fscsi3 ):
        0514-061 Cannot find a child device.

2、# chdev -l hdisk19 -a pv=yes
hdisk19 changed

4、# extendvg datavg hdisk19

二、Aix系统smitty扩lv空间

1. Telnet 192.168.10.200 (小机ip地址)，df -g查看文件系统空间使用情况，lsvg datavg1查看指定vg现况，下图看到还有203个PPs，即203*1024MB=203GB的空间空闲，可以扩到lv上。

2. smitty  jfs2，进入扩空间状态。本文要扩datavg1下的oradata_lv1，其格式为jfs2
 
# lsvg -l datavg1
datavg1:
LV NAME             TYPE       LPs     PPs     PVs  LV STATE      MOUNT POINT
oracle_lv1          jfs2       20      20      1    open/syncd    /oracle
oradata_lv1         jfs2       7190    7190    15   open/syncd    /oradata
install_lv1         jfs2       20      20      1    closed/syncd  /install
loglv01             jfs2log    1       1       1    open/syncd    N/A
 
3. 选择 Change / Show Charac.......，然后选择要扩的lv名，这里是/oradata，回车。
 
 
4. 选中Unit Size....一行，按ESC+4键，改变512bytes改为Gigabytes。然后鼠标移到Number of units一行，在括号里输入7190，即此lv空间从7000扩到7190个PPs空间大小，回车执行扩展。
 
 
5. lv扩容，查看情况。
