thanks for the reply , but wouldn't that merge LV's from two different volume groups and for some weird requirement I wanted to merge LV's from the same VG , say
merge /dev/vg0/data and /dev/vg0/data1 into a merged volume without any data loss .

and the PE size must be the same in both VGs.
Basically this would be:
lvchange -a n /dev/vg02/lv01
lvchange -a n /dev/vg02/lv02
lvchange -a n /dev/vg02/lv03
...
vgmerge vg01 vg02
vgchange -ay
this would put all the LVs from vg02 into the vg01 VG.
