In short, the steps are:
Reboot or rescan the scsi bus:
echo '1' > /sys/class/scsi_disk/0\:0\:0\:0/device/rescan
Identify the correct disk:
This will be something like /dev/sda or /dev/vda.
Create a new partition with fdisk and label it as LVM (replace sdx with the correct disk):
Press p to print the partition table to identify the number of partitions.
Press n to create a new primary partition.
Press p for primary.
Press a number for the partition number, depending on the output of the partition table print.
Press Enter two times.
Press t to change the system's partition ID.
Press the number of the just created partition.
Type 8e to change the Hex Code of the partition for Linux LVM.
Press w to write the changes to the partition table.
Create a new PV (replace sdx and 0 with the correct disk and partition):
Extend the VG with the new PV:
vgextend vg_cpanel02 /dev/[sdx]
Extend the correct LV with all the available size (make sure this is the correct LV!):
lvextend -l +100%FREE /dev/vg_cpanel02/LogVol00
Now, the LV will be resized, the only thing left is to resize the filesystem.
You can use xfs_grow or resize2fs for this operation, depending on your used filesystem.
Expanding disks is shortly explained in the VMWare documentation:

Please, be careful. Reread your commands before pressing enter and test in a test environment if you are not sure you are doing the right thing!
