Looking partiton information on hard disks

[Paul Clayton]

Can anyone help. I am looking for the command that will get the partition (VTOC) of a hard drive.

On hpux there is not VTOC.

Older systems HPUX 09.xx used disk partitioning, but you cannnot defined it, just use some of defined.

Now HPUX uses Logical Volume Manager (LVM), and there is not VTOC.

Search LVM introduction on http://docs.hp.com

Hi,

in these days, LVM is used instead of partitioning disks. So you don't have a VTOC any more, but a data structure made by LVM. And of course you can display informations about volume groups, physical volumes and logical volumes:

vgdisplay -v /dev/vg00

pvdisplay -v /dev/dsk/c0t5d0

lvdisplay -v /dev/vg00/lvol5

volume group ---> one or more hard disks, which are now one logical disk

physical volume ---> hard disk, handeled by LVM

logical volume ---> the newer version of a "partition"

the option -v (verbose) gives you a more detailed output.

Allways stay on the bright side of life!

Attached is a LVM program that I got from the HP response center that gives even more detail when reading the LVM headers on a drive. I have found it to be really useful.
