HP-UX

Dear All,

We have HP Unix 11.31.

We have two VG, VG01 and VG02.

In VG01 there are three mount point each of 100gb size. There is no data on below mount point

Code:

/soft/01
/soft/02
/soft/03

Is it possible to resize each of these mount point to 50 GB. So 150 GB will free and release from VG01. I need 150 GB free space to create new VG, VG03.

I am new to HP Unix.

Request you to please suggest steps to do above activity.

Thanks,

Nirav

You should look at the actual disk layout under the mentioned volume group.

Code:

vgdisplay -v /dev/vg01

Check out for free PE's on specifed disk.
If the entire disk is free, you can use vgreduce on that volume group and reuse that disk.

Else, you will need to remove the vg01 volume group completly and reuse the disks as you see fit.

Hope that helps

Further to @Peasant and to stress the point.

This assumes that you do not have a modern SAN where the "discs" are resizeable.

A Volume Group is made up of a Group of Physical Discs (aka. Volumes). Any individual Physical Disc cannot be in more than one Volume Group. If you can release at least one whole disc from VG01, you can create a VG03 from the now-spare disc(s).
The only real reason to do this is if you are about to exceed the maximum number of Logical Volumes allowed in a Volume Group.
