问题：
现在两个节点hdisk40 PVID不同，创建卷组时的PVID都原始PVID是现在节点1上hdisk40的PVID 00cd1e155b966d41 ，节点2上的hdisk40本来也是 00cd1e155b966d41 ，后来经过chdev -l hdisk40 -a pv=clear ,chdev -l hdisk40 -a pv=yes之后，PVID已发生改变。现在在节点2上激活卷组yhvg是会报错且不能包括hdisk40，

尝试的操作：
1、
fbdb12:[/]#synclvodm -P -v yhvg 失败

0516-548 synclvodm: Partially successful with updating volume

2.、
fbdb12:[/]#redefinevg -d hdisk40 yhvg
0516-1939 : PV identifier not found in VGDA.
fbdb12:[/]#
希望高人指点下，这是测试环境，可以随便折腾。因为生产环境存在类似的问题，所以急需找到相应都解决方案。谢谢。
