Posting the exact error instead of "I'm getting an error that none of the volumes have increased in size." may also help us to help you...

oslevel and hacmp info wouldn't hurt either...

When I execute "chvg -g <vg name>" the error is:

0516-1382 chvg: Volume group is not changed. None of the disks in the
volume group have grown in size.
0516-732 chvg: Unable to change volume group vg name.

OS Level: 5.3.0.0

The boot info shows the old disk size. Not seeing the new size of 300GB.

# bootinfo -s hdisk3

What type of storage system are you presenting this LUN from?

Normally, when I want to grow an AIX VG. I add a new LUN to it instead of growing the LUN. This is what I would suggest, unless you have some sort of storage vendor software on the AIX server, such as SnapDrive for Unix from NetApp.

It's a Lefthand SAN. I thought about doing that but wondered if there was a way like in Windows.
