双VIOS，多个VIOC，VIOC的rootvg采用VSCSI,datavg采用NPIV
多路径采用EMC的powerpath

VIOS2的root用户做cfgmgr -v,命令一直执行不完成，VIOS上面hdiskpower5对应的VIOC有宕机，重新启动了.
ps -ef可以查到下面信息
root 12255474 18939924 120 10:57:54 pts/2 0:44 /etc/methods/cfgpowerdisk -l hdiskpower5
root 18939924 18219256 0 10:57:54 pts/2 0:00 cfgmgr -l powerpath0
root 18219256 22413536 0 10:57:53 pts/2 0:00 /usr/sbin/powermt config
root 22413536 24379538 0 10:57:51 pts/2 0:00 cfgmgr -v

进程12255474没有办法kill掉,上面进程的其它进程可以kill掉,由子进程12255474开始kill，最后kill -9 22413536

所有的VIOC，除hdiskpower5对应的VIOC异常宕机重启了，VIOC的errpt只有启动记录。其它VIOC正常。
宕机的VIOC启动完成后，对VIOS2重启了，重启过程中，所有的VIOC全正常。

没有在padmin下操作cfgdev扫硬件，是因为powermt命令在root下执行方便。
