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?
Show us the output of
vgdisplay -v vg00
# vgdisplay -v vg02

Have you read about the vgextend command?
Man Page for vgextend (all Section 1m) - The UNIX and Linux Forums
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
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.
That was not vgdisplay output of vg00...
What does swapinfo -tam give you?
What kind of system is this?
PE Size (Mbytes) 4
Total PE 2287
That makes the size of the disc 4 x 2287 = 9148 Mb (about 9 Gb).
It is possible that you specified a "-s <size>" parameter on "pvcreate" and artificially made the disc smaller.
Perhaps that the disc is a "dd" copy from a 9 Gb disc.
Could even be that the O/S is so old that is does not know how to deal with 36 Gb discs.
Thanks every body for the answers, finally I couldnt find a solution, so I recreate the volume group with the maximun size of the disk and I duplicate de logical groups. Maybe it was not the best solution, but it works, and also I couldnt wait more time
There were no other alternatives...You've learned the hard way what can happen when an installation was done immediately after reception without more brainstorming (accepting defaults...). on a 10.20 this is also true for the size / , swap (vg00/lvol2), /stand...
It showed you what being proactive means (likely the disk size (PV) tend to grow, how much should I enter for its max size knowing the value cannot be changed after...)
