Single command to Partition and label as LVM whole disk

Hello,

someone please suggest me how write a script or command to create partition and label whole disk as LVM . I have multiple servers that I to label as LVM using fdisk, that will very hard process.

This is what I currently doing to create to partition and label.
Code:
# fdisk /dev/sdb

The number of cylinders for this disk is set to 5221.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-5221, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-5221, default 5221):
Using default value 5221

Command (m for help): t
Selected partition 1
Hex code (type L to list codes): 8e
8Changed system type of partition 1 to 8e (Linux LVM)

Command (m for help): p

Disk /dev/sdb: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        5221    41937651   8e  Linux LVM

Command (m for help): w
