How to resize a partition on centOS 6.3 (VMware VM on ESX)?

I need to expand the partition (main) on a centOS 6.3 VM, it is also a virtual machine running on ESX 5.1. I have increased the file storage successfully within VMware ESX, but need the steps to increase the size within the operating system.

Here is the specs:

df -h
vmware view
centOS 6.3
LVL 2

You mostly would do that with:

lvm pvresize --setphysicalvolumesize <size> <physicalvolume>

and then

lvm lvresize --size + <size> <logicalvolume>

1. Check the disk in OS with fdisk -l
2. Create a physical partition of required size and change the type to "Linux LVM"
3. Create the PV of newly created FS #pvcreate /dev/sdxx
4. Extend the vg by PV size so the space can be used in LV resize #vgextend <vg> <pv>
5. Resize the LV #lvextend -L+<size>G <lv>
6. perform online resizing #resize2fs <lv>
7. Verify with #lvs and #df -h

What do you mean with 'pre-environment'? If you mean, booting with a Live system like Part Image: yes, i'd do it that way.
