both copies reported by the command lslv are on the physical volume of rootvg: hdisk0 and hdisk1.
Both copies will not affect the datavg vg.
In fact I try to delete, without impacting applications, the problem of name conflict logical volume on this server. There are two times the logical volume lvnode01 : once in the volume group rootvg (mounted and active) and a second time in another volume group datavg (unmounted, not in the ODM but present in VGDA off physical volume related volume group datavg).
After some research I think the command synclvodm could solve the problem of name conflict by renaming the logical volume automatically by default.

Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.
If I extend LogVol01 further by 10GB, then it keeps the extended copy after logical volume 2. I want to know where it keeps this information
