Increase Size of a Volume Group
Hi I have hp-ux 10.20

I have have my operating system VG of 7 GB in a 36Gb disk. So I have like 29GB of unused disk space. There is any way to increase my VG size, or to add another VG in the same disk so I can use all the disk space?

Another question, what is the maximun size that a VG can be in hp 10.20?

I did it.. but It doesnt really say´s anything clear how to increase or add another colume group. I tried from SAM, but it doesnt let me change, it says that the physical volume already belong to a group

Can you
Code:
vgcreate VG02 /dev/dsk/c0t4d0

(Trying to do this from my memory.) Essentially trying to create a 2nd volume group from what is not yet allocated on that disk drive.

You're on an older version of the OS, but I know in current versions using LVM, you can't create more than one volume group on one disk.
