Re: LVM upgrade

If you run hp-ux 11.31, make a backup and use update-ux to go to the latest release.

Hope this helps!

Re: LVM upgrade

Torsten means you'll need a March 2009 release of HP-UX 11.31 (or newer) to have the LVM version upgrade capability.

 

Please see this whitepaper (titled LVM Volume Group Version Migration):

Re: vg upgrade from 1.0 to 2.1

Re: vg upgrade from 1.0 to 2.1

Do you want to extend the VG?

I'm not sure about your problem.

Sounds like "vgmodify" could help you.


>> maybe i need to explain more

Yes, please.

Hope this helps!

Re: vg upgrade from 1.0 to 2.1

I have a vg that is 1.0 i need to extend the vg and the lv, it says that i cant. After doing some research i have read that it needs to be level 2.1 to extend the vg past where i am. Is there a way to make the vg 2.1 with rebuilding it?

Re: vg upgrade from 1.0 to 2.1

I'm not sure if this solves your problem, because i dont know what your problem is ...

 

How about an exact commands and error messages???

 

vgdisplay output etc etc???

 

 

vgversion command can be used to "upgrade" volume groups, btw.


Hope this helps!

Re: vg upgrade from 1.0 to 2.1

yes the vgversion is the command i was looking for but it doesnt appear that it can be done LIVE, it looks like i ahve deactivate the vg to do this.....I was trying to do it without taking down the vg since this is a live system..

Re: vg upgrade from 1.0 to 2.1

VG must be deactivated for migration.

 

 

If you could tell more details about your problem we probably can help you ...


Hope this helps!

Re: LVM upgrade

Assuming you have the software for LVM v2 loaded you can do a online upgrade with vxupgrade command that should be included with LVMv2 with one of the recent OE releases of 11.31.  Volume group must be deactivated and this cannot be done for vg00.

 

It seems to work fine with the systems I have done it to.

 

VG00 can be lvmv2 but only from a install as far as I know... (I could be wrong)

 

Good luck.. try it with a small VG first. it changes the structure of the VG and can be revered if no other changes have been made.
