volume group cannot be extended

The following is the error message I'm getting when I try to extend vg02. Can this limitation be modified?

========================================
Volume group "vg02" currently contains 16 physical volumes, which is the maximum number of physical volumes it was configured to contain. This volume group cannot be extended.

Re: volume group cannot be extended

If you are running hp-ux 11.23 or 11.31, this could be your solution:

Usage: vgmodify
[-e MaxPhysicalExtents]
[-p MaxPhysicalVolumes]
[-l MaxLogicalVolumes]
[-v]
[-n]
[-r]
[-B bootable]
VolumeGroupName {[pv_path] [pv_path] ....}

or vgmodify -o [-v] [-r] [-B bootable] VolumeGroupName {[pv_path] ....}

or vgmodify -t [-v] [-n] [-B bootable] VolumeGroupName {[pv_path] ....}


Hope this helps!
Regards
Torsten.

Re: volume group cannot be extended

Jacques,
It´s a default configuration, can´t be modified. In new creations, the default configuration can be modified:
vgcrete -p 255 (the maximum) vg_name.

Re: volume group cannot be extended

If you are using 11iv3, you can use the vgmodify command to modify the the max_pv attribute.
Dying is the last thing that I will do.

Re: volume group cannot be extended

Hi Jacques:

If you are running 11.31 you can use 'vgmodify' to alter the maximum number of physical volumes in the volume group. If you are running 11.23, and you have patches PHCO_36744, PHKL_36745 and PHKL_36746, then you can use 'vgmodify', too.

If you are running 11.11 or earlier, you must totally recreate the volume group from scratch, this time specifying '-p max_pv' when you execute 'vgcreate'.

For 'vgmodify', see:

http://docs.hp.com/en/B2355-60130/vgmodify.1M.html

Regards!

Unfortunately, this server is at 11.11 and cannot be modified.

Re: volume group cannot be extended

IIRC, Robert-Jan attached an *unsupported* version for 11.11 recently.
With some luck you can find it ...

Hope this helps!
