Re: Vg problem max PV
Sorry, once a volume group is created, you can't modify its 'pv_max', 'max_pe', 'pe_size' nor 'max_lv' without recreating it. Plan ahead is the axiom here.

SolutionGenerally, true; you should pump that parameter up when generating vgs in the first place.
I usually use:
vgcreate -l 255 -p 64 -s 8 -e 10000 ${vg} ${pvs[*]}
That, so far, has given some good flexibility.
All that being said, I have seen several posts that tell about an unsupported HP script that will allow you to modify preexisting vg parameters. You apparently have to open a tt w/HP to get it and then promise you won't sue them if you use it...

Re: Vg problem max PV
Sorry - it can't be done.
Once it's set at creation, it's set forever.
The only way to change is backup the data, destroy the VG and rebuild a new one specifically setting the value(s) on the vgcreate command line.
Rgds,
Jeff

Re: Vg problem max PV
It's an unsupported Tool. I think it's only
supported if a HP stuff do the action with this tool.
