to identify failed pv

Hi friends,....
am sindhiya,
i have joined as AIX level 1 support.
help me to identify the failed pv in vg which has some 4 physical volumes?

Start with a look into the errpt, use the -a option to get a detailed view. If a disk broke down completely lsvg -l <yourvg> my be worth a try too.
And if you want to make a living from being an AIX administrator start both reading (red)books and get some professional training in the beginning.

thank u ....so much...
