Hi,

I am not sure what is your query but if you want to know what is LVM all about then here it is.

http://docs.hp.com/en/B9106-90013/lvm.7.html

The same information is also available on any of your box running HPUx by typing "man lvm".

Feel free to revert if something else is to be clarified.

Hi,

Again it is a little confusing what you are asking. If you mean in which structure it stores data then it consists of following term which are also mentioned in man page.

Physical disk called as physical volume after converting to LVM disk using pvcreate command.

A Volume Group(VG) can be create on this disk using vgcreate command. If your system allready has a VG then you can extend your existing VG to this disk using vgextend command.

A VG has the Logical volumes created in it. There may be as many as 255 Logical volumes in a VG.

These LVOL's are used for creating a file system or used without creating a file system as swap or raw devices for databases.

In the end of link provided in earlier post there are commands which will took you to man page of all those for more clarifications.
