So I have some space left due to "thin" provision for my VMware guest. I created the physical drive(/dev/sdb3) by fdisk and then added to the existing LVM as follow:
[root@php-bob ~]# pvcreate /dev/sda3
Physical volume "/dev/sda3" successfully created
[root@php-bob ~]# vgextend VolGroup00 /dev/sda3
Volume group "VolGroup00" successfully extended
[root@php-bob ~]# lvextend -L+25G /dev/VolGroup00/LogVol00
Extending logical volume LogVol00 to 43.88 GB
Logical volume LogVol00 successfully resized
[root@php-bob ~]# resize2fs /dev/VolGroup00/LogVol00
resize2fs 1.39 (29-May-2006)
Filesystem at /dev/VolGroup00/LogVol00 is mounted on /; on-line resizing required
Performing an on-line resize of /dev/VolGroup00/LogVol00 to 11501568 (4k) blocks.
The filesystem on /dev/VolGroup00/LogVol00 is now 11501568 blocks long.
