Can't find LVM after creation?

This is probably a very dumb question, but basically when I installed CentOS 6 on a server with RAID10 set up, I created a LVM partition, but I could not find the LVM in the server now.

Here is my df -h output:

df -h
Filesystem Size Used Avail Use% Mounted on
/dev/cciss/c0d0p2 39G 2.1G 35G 6% /
tmpfs 12G 0 12G 0% /dev/shm
/dev/cciss/c0d0p1 194M 146M 38M 80% /boot`

And fdisk -l

fdisk -l

Disk /dev/cciss/c0d0: 1000.1 GB, 1000148590592 bytes
255 heads, 32 sectors/track, 239389 cylinders
Units = cylinders of 8160 * 512 = 4177920 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00048f66

      Device Boot      Start         End      Blocks   Id  System

/dev/cciss/c0d0p1 * 1 51 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/cciss/c0d0p2 51 10090 40960000 83 Linux
Partition 2 does not end on cylinder boundary.
/dev/cciss/c0d0p3 10090 11094 4096000 82 Linux swap / Solaris
Partition 3 does not end on cylinder boundary.

Output of pvscan:

No matching physical volumes found

No volume groups found

So my question is:

  1. Is the LVM actually installed?

and 2. If it is not, is there anyway I could get it up and running without reinstalling the server? The server has a hardware RAID10 set up with 4x1TB disks.
