VGMODIFY - HPUX 11iv2 system

I want to re-confirm some steps to increase the max PVS for a volume group. heres what I know.


1. can run 'vgmodify -tv volgroup' to see table of values.
2. The volgroup is cluster owned/aware so I need to halt the package.
3. After package is halted, make the cluster unaware with 'vgchange -c n /dev/volgroup'
4. deactive it with 'vgchange -a n /dev/volgroup' (is this step needed????)
4. apply the change with 'vgmodify -p xx volgroup' xx is my new max numbers of pVs
5. reactive it with 'vgchange -a y /dev/volgroup'
6. run 'vgdisplay /dev/volgroup' to confirm the changes.
7. deactive the volgroup again. (-a n)
8. make the volgroup cluster aware (-c y)
8. start my package

Thanks Rita.
I had documented these tasks a short time back but left out a step or two. Was re-confirming!

Re: VGMODIFY - HPUX 11iv2 system

Forgot to answer #4:

Per the manpage on 11.23 for vgmodify:

"... The volume group can be active when reporting the configuration (-r) or displaying a table of available settings (-t). The volume group must be de-activated before vgmodify can perform any configuration
changes (see vgchange(1M))."
