增加某个文件系统的空间
1. df -g | grep /home 查看/home所属的逻辑卷，假设是hd1
2. lslv -l hd1 查看hd1所属的物理卷，假设是hdisk0
3. lspv -p hdisk0 查看物理卷的可用空间
4. smitty chfs 或者 chfs -a size=+10G /home
5. 如果执行上述命令时出现问题:Maximum allocation for logical volume hd1，运行命令
chlv -x 800 hd1 或 smitty chlv 或 smitty lv

6. extendlv与chfs是很接近的，但增加文件空间需要用chfs，不要用extendlv，因为extendlv会扩大逻辑分区，但不能反映的文件空间上的。
