how do i ando a vgmodify -u

Hi Andre,

There is no vgmodify command. Would you be referring to vgchange? But even that doesn't have a -u parameter.
What are you trying to do?

Hi,

What you are refering to is probably some third party tool which comes in discussions some times in the forum. But no forumer will be aware of it as it is not supported by HP.

HTH,

Hi

Like others who have mentioned here ,there is a vgchange command which is for the volume group availability.

from the document "When Good Disks Go Bad" located at http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad.pdf

bottom of page 31, you can see this innocent comment.

The volume groupâ s extent size and number of physical extents per disk are not dynamic. The only way to use all of the disk is to recreate the volume group with new values for the â s and â e options. Alternatively, you may be able to use the vgmodify command, available from your HP support representative, to adjust the volume groupâ s characteristics.

I think the user is referring to this command. Alas I do not have it, hence no man pages here.

What are you trying to do with the '-u' switch?

I got a copy of vgmodify at one point, I believe from a Forums post, and the is no '-u' option.

The following options are available in the version of vgmodify I have:

# ./vgmodify -?
Usage: vgmodify
[-e MaxPhysicalExtents | -d DiskSize]
[-p MaxPhysicalVolumes]
[-l MaxLogicalVolumes]
[-r]
VolumeGroupName [pv_path] [pv_path] ......

I urge you to use caution with this program. I might work and it might not. It is also possible that it my corrupt your VG, in which case you might have to restore all of your data.

I tried using this program once or twice in a test environment and it did not work for me either time.

To obtain vgmodify you must contact the Response Center.

It's a highly dangerous tool, provided as-is. Use it at your own risk.
