you get a warning about it changing your bootimage....but you don't have to
vary it off...you also can't import it into a pre 4.3.0 system if you do
that...i just did it this morning, and it didn't erase anything...and that
vg had data on it, but this wasn't a production server.

Subject: Adding a bigger disk to a volume group

Hi,

Server M80 running AIX 4.3.3

I tried to add a bigger disk(36.4 GBs) to a volume
group of which the PP size currently is 32 MGs.
Because it exceeded the limitation number of 1016 PP,
it failed. In the error message, it advised me to run
'chvg -t' to enlarge the PP size of the volume group.

My question is: Would this 'chvg -t' command destroy
my volume group information, making my volume group
useless? Anyone can help me out? Does the volume
group have to be varyoff beforehand?

Thank you in advance.
