I doubt you can change it.

Bill/Basim,
If I remember, I never got a situation to chose -t option to fit more
PP in PVs. Is these any chance to force itself to fit more PPs in PV
when you chose small PP size while creating big volume group?I think I
did a mistake while choosing PP size, 32mb for 550GB volume group
what chances I have to make this volume group big? Is it possible with
chvg -B option if I umount and close all LVs in that VG. I want this
volume group to mirror and then break to move all data to new shark
storage.
Thank You.

you have changed the limit of the number of physical partition per
physical
volume using 'chvg -t 4' in order to larger disk size to smaller PP
size
volume group. This will reduce the max number of PVs per VG

Thanks Bill,
I have a volume group with MAX PVs 8 and MAX PPs per PV is 4064. In
this circumstances, can I change MAX PVs to 32 by using chvg -B
option.
For some reason I was unable to change MAX PVs number since I want to
add new disks(we re doing shark migration).
How can volume group get MAX PVs to 8 when default is 32.
thanks once again.

By default it is 32. There is no need to make it smaller. -B means
'make
it a Big' volume group. -G means 'Gigantic'.

Hi Guys,
How to change volumegroup to set MAX PVs to 20. When I tried chvg with
-B option it goes 128 PVs.
Is these any other way to set MAX PVs other than using chvg -B
<volumegroup>.
thanks
muthyam
