最近一直都没有写什么东西，今天就把一个实际工作中的针对LVM的TROUBLESHOOTING过程贴出来吧。
事情的起因是这样：一台机器升级到了AIX5.2，而且原先的FAStT不用了，直接用光纤卡接EXP；由于原先EXP上的6块硬盘两两作了RAID1，这样就造成6块硬盘只有3个PVID；一同事新建了一个VG后造成这个VG不仅无法VARYON，而且也删不掉了。
我下面的过程就是手工改变重复的PVID，并通过ODM将错误VG删掉。

至此，重复PVID的问题解决了，其中用到的脚本来自AIX Logical Volume Manager from A to Z Troubleshooting and Commands（sg245433）中的chpvid。下面解决的是，错误的datavg无法删除的问题。
