rootvg修改pp大小的实验。。。
本人手上有台630 平时做个人测试环境用 呵呵 前几天看到有篇讲aix里修改vg的pp size的帖子 反正闲来无聊 准备在家自己实验下 然后把过程结果发到论坛上:lol rootvg的ppsize大小应该是你安装操作系统时硬盘的大小而自动设置的(rootvg属于normal vg 所以最大...显示全部
本人手上有台630 平时做个人测试环境用 呵呵 前几天看到有篇讲aix里修改vg的pp size的帖子 反正闲来无聊 准备在家自己实验下 然后把过程结果发到论坛上:lol
rootvg的ppsize大小应该是你安装操作系统时硬盘的大小而自动设置的(rootvg属于normal vg 所以最大的pv不能超过32 每个pv上面的pp不能超出1016） 一般73.4G的硬盘为128m 146G的为256m 除了rootvg其他的vg在建立的时候是可以自己设置pp大小的
下面看下没修改前得ppsize大小：

显示是128m的 我想把它改成256m的 接下来就可以进行实验了：
1.创建image.data

2.编辑生成的image.data
vi image.data 改变PPSIZE只能改大，系统默认的ppsize是最小的情况，就是1016（每个PV最多1016个PP）的限制。并非一定改大，如果你的很大，可以改小。

3.mksysb
mksysb /dev/rmt0
注意：不能加 -i等参数，不能让mksysb再生成新的image.data
4.restore
重启把backup好的tape放进磁带机，进入维护模式里面有install backup的选项，一步步来就可以了，不过这个磁带恢复要等的时间比较长，需要耐心的 呵呵
5.接下来就是进入系统后所看到修改好的ppsize了
