AIX首次使用困难
今天第一次使用AIX，碰到了不少问题啊
1.第一个就是xmanager连不上，这个是自己的粗心，忘记吧本地的防火墙关闭了，造成就是不出界面
2.发现空间不足，通过命令首先查询硬盘的大小
# df -k

/dev/hd4?????????? 131072???? 25660?? 81%???? 2425??? 29% /

发现/usr下空间只有10G空闲，需要安装的东西光安装介质就6G了，所以空间不够。

发现有大约55G的空闲空间，将他非配给/usr就可以了
#chfs -a size=+60000000 /usr
(60000000*512/1024/1024/1024 .= 30G)
将大约30G的空间分配给/usr
