Creating a logical volume file

jamie2teach · February 23, 2012, 6:51am

Hi to all,

I am brand new to HP-UX but am quite familiar with Linux systems (Red Hat, Ubuntu etc..)

I've just taken over a new HP-UX box and trying to work out how to create a logical volume.

As well as creating the volume, which I am sure is very easy I need to create a special character file for an Oracle database datafile.

Some details:

# vgdisplay -v vg02
--- Volume groups ---

What I am trying to do is create a special file like the "r_css_pagf9"

Unfortunately the person that usually deals with this is no longer available and I am having to do his job for him and hence the assistance.

Any questions? Please ask.

Thanks to all that reply.

Could you say more about your system (model, OS version...) for I am a bit surprised by what I see...
I would like to see vg00 display and more the output of bdf command to understand a bit...
By the look at things, you never had disk issues... (your display is a bit scary for someone used to solve sever issues...) or did the guy in charge realized and ran away before?( with such implemetation you need really good backups AND documentation on all config stuff...)

First of all, please do use code tags around while posting outputs/commands for readability.

Creating volume groups in HP-UX is a lot similar to doing that in RHEL or Linux. Use lvcreate command to create a new logical volume.

lvcreate -L size_in_MB /dev/vg00

Download this document from HP for more info on LVM:

Hi,

Sorry about that. I am not actually putting the code tags in. All I am doing is copying and pasting to and from and it seems to add it as a code tag.

I've actually been able to work out how to create the logical volume now. I am now just having a problem with creating a raw datafile for an Oracle database but this is another problem.

Thanks for all the assistance.

Why is it we see no vg02 lvols mounted? where is vg00/lvol10?
Have you noticed the difference between vg00 and vg02 (lvol names...)?

I suggest you use SAM (System Administration Manager, sam command) to go through the creation of such devices, for sam will check before execution (e.g. size...). Later, use command line, its faster...
I have no IA64 so menu may differ...
choose "Disk and File Systems", "Logical Volums" (Little delay: the system scans its HW...)
On the menu bar, choose "Create" then choose the VG, validate, then go to next option:
"Define new Logical Volume", a new widow will open:
choose lvol name
Give size...

It will create automatically the JFS Filesystem in it...

All the best

In the same Last window there is a menu box: choose ( I think - I have no oracle raw FS...) "raw" instead of Filesystem, I you choose swap it will create a syste swap device (no good...)
