Getting below error while doing vgextend. I am having HPUX 11.31; want to increase either max_pe_per_pv or PE size paratmeter online, is it possible?
vgextend: Warning: Max_PE_per_PV for the volume group (2303) too small for this PV (2457).
Using only 2303 PEs from this physical volume.

You can try using the 'vgmodify' command. See 'man vgmodify' for details.
To increase the max_pe_per_pv values you can try something like:
vgmodify -e 4000 -n /dev/vg02
to increase the max pe per pv to 4000.
There are other useful examples in the man page as well.

In order to use vgmodify you need to have LVM version 2. With the command lvmadm -l you can see the version of all your VG. If you have VG in version 1.x, you need to migrate (you need 20Mb aprox in each PV)
vgchange -a n <vg>
vgversion -v -V 2.2 <vg>
vgchange -a y <vg>
And then ypu can use the command vgmodify -e

It works with version 1 too.
Hope this helps!
