# vgexport -m /tmp/vg03.map /dev/vg03
# rm /dev/vg03/group
# mknod /dev/vg03/group c 64 0x030000

Hi Shri and Robert,

Many thanks to you guys... Unfortunately, in my box, the patches for Vgmodify was not installed. So, I had to delete LV, VG and recreated it.

The document, which Robert given was very good. I had tested it on my test server (version 11iv3) and successfully worked.

Sajjad,

You may go through the querry, you can understand, what I really needed.

Guys, thanks for the help and sorry for the delayed response and closure.

I went thorough
u understand one thing, if u are going to change u minro number, in order that u exporting u volume group also
that means u removing u volume and creating new one i mean wiht new name which i meant.
